FIELD OF THE INVENTION
[0001] This present disclosure relates to an apparatus and method to attach a control line
to a tubular member. More specifically, the present disclosure relates to an apparatus
having a control line arm having a control line guide.
BACKGROUND OF THE DISCLOSURE
Description of the Related Art
[0002] A pipe string is generally installed in a drilled borehole by lowering a distal end
of a pipe segment or a pipe string into the borehole, supporting the pipe segment
or the pipe string from its proximal end using a pipe engaging apparatus, threadably
coupling a pipe segment to the proximal end of the pipe string above the rig floor,
and again lowering the lengthened pipe string into the borehole. This process is repeated
until the pipe string achieves the desired length, after which it may be positioned
within a targeted interval of the drilled borehole and cemented into the borehole.
[0003] The pipe string is generally supported within the borehole from its proximal end
using a stationary spider or a collar load support (CLS) landing spear at or adjacent
to the rig floor so that an additional pipe segment may be coupled to the proximal
end of the pipe string to lengthen the pipe string. A vertically movable elevator
assembly, such as a string elevator or casing running tool (CRT), may be movably suspended
above the spider or CLS landing spear to engage and support the pipe string from its
new proximal end (at the proximal end of the newly added pipe segment) to unload the
spider or CLS landing spear. After the spider or CLS landing spear is disengaged from
the pipe string, the pipe string may be lowered into the borehole by lowering the
elevator assembly, and the spider or CLS landing spear may be reengaged just under
the new proximal end of the pipe string.
[0004] The spider or CLS landing spear is supported by a rig in a manner that distributes
the load of the pipe string to structural components in or under the rig floor. Alternately,
when the load of the pipe string is supported by the elevator assembly, the load of
the pipe string is distributed to structural components of the rig through a block,
a draw works and a derrick to unload the spider or CLS landing spear so that it can
be disengaged and opened to permit enlarged portions of the pipe string, such as pipe
joints, to pass through the spider or CLS landing spear into the borehole. Specifically,
to transfer the load of the pipe string from the elevator assembly back to the spider,
the slips of the spider must engage and grip the exterior surface of the pipe string
so that the pipe string can be supported by the spider and then released by the elevator
assembly. Similarly, to transfer the load of the pipe string from the elevator assembly
to a CLS landing spear, the halves of the CLS landing spear must close on and surround
the exterior surface of the pipe string just below a pipe joint so that the pipe string
can be supported by the CLS landing spear and then released by the elevator assembly.
[0005] Oil and/or gas wells may be equipped with control lines for electrically, fluidically
or optically linking various downhole devices to the surface. For example, control
lines may be used to receive data from downhole instruments and to selectively operate,
from the surface, downhole devices such as valves, switches, sensors, relays or other
devices. One use of control lines may be to open, close or adjust downhole valves
in order to selectively produce or isolate formations penetrated by the borehole.
A control line may also transmit data gathered downhole to the surface, and control
lines may transmit commands from the surface to downhole devices.
[0006] Control lines may comprise conductive wires or cables for electrically controlling
downhole devices, fibers for optically controlling downhole devices, or small-diameter
tubing for fluidically (e. g., hydraulically or pneumatically) controlling downhole
devices. Control lines are generally of a small diameter compared to the diameter
of the pipe string to which they may be secured, and are generally between 0.5 and
6 cm. in diameter. Control lines may be generally aligned along the length of a portion
of the outer surface of a pipe string, generally parallel to the center axis of the
bore of the pipe string, and secured to the pipe string using clamps, ties, straps,
etc. Although pipe strings generally comprise a plurality of pipe segments coupled
together at pipe joints, a control line is generally continuous or has few joints
along its length in order to eliminate or minimize couplings along the control line.
Control lines may be stored on a reel that may be brought to the rig and unreeled
as the control line is secured to the pipe string and installed in the borehole.
[0007] A pipe string is generally made-up and run into the borehole using a spider supported
in or on a rig floor. The spider may comprise a tapered bowl that movably receives
pipe slips that converge to engage and grip the pipe string, and retract to release
the pipe string. Alternately, a collar load support (CLS) landing spear may comprise
a pair of halves that can be closed around the pipe string to support a load transfer
sleeve that engages an upper collar of the pipe string, as disclosed in
U.S. 6,651,737, a patent that is assigned to and owned by the owner of the patent rights related
to this disclosure. An elevator assembly, such as a string elevator or a casing running
tool (CRT), is generally vertically movable above the spider or the CLS landing spear,
and may be used to engage and movably support the pipe string so that the pipe string
can be released at the spider or CLS landing spear, and so that the lengthened pipe
string can be lowered further into the borehole. Whether a spider or a CLS landing
spear is used to support the pipe string, during this critical "hand-off' step, the
one or more control lines must be positioned and protected so that they will not become
damaged. A control line secured to a pipe string is subject to being damaged and rendered
useless if it is pinched or crushed between the tapered bowl and the slips of a spider,
two adjacent slips of a spider, the halves of a CLS landing spear, or the pipe string
and another structure. For example, but not by way of limitation, a control line may
be damaged if it is pinched between the pipe string and the pipe slips that may be
movably received within the tapered bowl of a spider to engage and grip the pipe string.
Similarly, a control line may be damaged if it is crushed between the pipe string
and the wall of the borehole as the pipe string is lowered into the borehole. If a
control line is pinched or crushed, it may be necessary to remove the entire pipe
string from the borehole in order to remove and replace the damaged control line,
thereby resulting in a substantial loss of valuable rig time.
[0008] The control line may be secured to the pipe string using a clamp, tie, strap, band
or other device. For example, but not by way of limitation, a protective clamp may
be applied to secure the control line to the pipe string and also to protect the control
line at critical positions along the pipe string, such as at pipe joints. Some control
line clamps comprise an elongate guard member, shaped to cover and shield a portion
of the control line adjacent to a pipe joint, and end portions that may couple to
the guard member to secure the guard member to the pipe string and to secure the control
line to the pipe string.
[0009] When running one or more control lines into a borehole along with the pipe string,
it is important that the pipe slips of the spider engage and grip the pipe string
in a manner that prevents crushing or damaging the control line while making up the
pipe string. It is advantageous if the control lines can be positioned out of the
zone of operation of the spider, or the CLS landing spear, when the spider is engaged
to grip, or the CLS landing spear is closed to support, the pipe string. A control
line positioning apparatus, such as a pivotable arm, may be used to position a portion
of one or more control lines to prevent exposure of the control lines to crushing
or pinching by the spider or by the CLS landing spear. Optionally, a rig floor, a
shock table, the tapered bowl of a spider, or some other structure to support the
spider or the CLS landing spear may comprise a groove, bay or recess into which the
control lines can be positioned using the control line positioning arm to protect
the control lines during operation of the spider or the CLS landing spear. After the
load of the pipe string is transferred to the elevator assembly to unload the spider
or the CLS landing spear, the control line positioning arm may then be actuated to
reposition the portion of the control lines from the groove, bay or recess to a raised
position proximal the pipe string but above the disengaged spider or the opened CLS
landing spear so that a portion of the length of the control lines lie along the exterior
surface of the pipe string to facilitate application of a clamp.
[0010] One or more reels on which control lines are stored may be disposed on or near the
rig floor, and unreeled to supply control lines to the control line positioning apparatus
that is on the rig floor proximate the pipe string. In order to prevent a hazard to
personnel and equipment on the rig floor, the control lines may be directed overhead
to one or more guide members, such as a sheave or roller, supported above the rig
floor. For example, control lines may be fed from a reel, and one or more guide members
supported from the derrick and redirected toward the control line positioning apparatus
on the rig floor. Alternately, the control lines may be routed through a radially
more direct path to the control line positioning apparatus and to the pipe string
along a path that is substantially radial to the axis of the pipe string and spaced-apart
from the rig floor, but this arrangement is more likely to interfere with rig floor
activities and equipment.
[0011] What is needed is a method of safely securing control lines to a pipe string as the
pipe string is being made up and run into a well. What is needed is a method and an
apparatus that shelters control lines and prevents damage to control lines being secured
to a pipe string and installed in a borehole with the pipe string. What is needed
is a method and apparatus to reliably position control lines and to provide a reliable
control line feed to a control line positioning device, and to prevent the control
lines from entering the operating zone of a spider or a CLS landing spear unless the
spider or CLS spider is disabled from closing around a pipe string. What is needed
is a method and an apparatus to deliver a control line feed to a control line positioning
device that routes the control lines along a path that will not interfere with personnel
or equipment on the rig floor.
SUMMARY OF THE CLAIMED SUBJECT MATTER
[0012] The present disclosure satisfies one or more of the above needs by providing a control
line positioning method and an apparatus to use on a rig to position and protect one
or more control lines, and to facilitate clamping of control lines to a pipe string
using, for example, clamps, ties, straps, bands, etc. (hereinafter these are collectively
referred to herein as "clamps"). Clamps may be installed at spaced intervals along
the length of a pipe string as the pipe string is made-up and run into a borehole.
In one embodiment, the present disclosure provides a control line positioning method
and apparatus to protect control lines by positioning and restraining control lines
from entering the operating zone of a spider or a CLS landing spear, and to prevent
control lines from being pinched, crushed or otherwise damaged by such operation,
which includes the movement of components of a spider or the closure of the halves
of a CLS landing spear.
[0013] In another embodiment, the present disclosure provides a control line positioning
method and an apparatus to position control lines to be clamped to a pipe string while
the pipe string is received through a pipe engagement apparatus and supported by an
elevator assembly above the pipe engagement apparatus. The apparatus may comprise
a control line retainer arm that is movable between a removed position, with the control
lines restrained from entering the operating zone of the pipe engagement apparatus,
and a raised position to position the control lines along the pipe string above the
pipe engagement apparatus. In one embodiment, the control line retainer arm may comprise
a receiving member to be removably received within a receiving assembly adjacent to
the pipe engaging apparatus when the control line retainer arm is moved to a removed
position to restrain the control lines from entering the operating zone of the pipe
engaging apparatus. In another embodiment, the control line retainer arm may comprise
a docking member to be releasably coupled to a docking assembly adjacent to the pipe
engaging apparatus when the control line retainer assembly is moved to its removed
position to restrain the control lines from entering the operating zone of the pipe
engaging apparatus, and the control line retainer arm may be released from the docking
assembly and moved, using a drive member, to position the control lines along a portion
of the pipe string, and generally along a side of the portion of the pipe string that
is radially disposed toward the control line retainer arm. The control lines may be
held in that position as they are clamped to the pipe string.
[0014] Some embodiments of the control line positioning apparatus may be used with a safety
interlock system to prevent damage to control lines. For example, but not by way of
limitation, a docking assembly may be positioned adjacent to the pipe engagement apparatus
and used to releasably couple to the control line retainer arm and to secure the retainer
arm in its removed position during engagement of the pipe engaging apparatus with
the pipe string. In one embodiment, the docking assembly may be mechanically, fluidically
or electrically coupled to the pipe engaging apparatus to provide a safety interlock
system preventing release of the control line retainer arm from the docking assembly
until the pipe engaging apparatus is in a disengaged or open condition. In one embodiment,
when the pipe engaging apparatus is in the disengaged or open condition and the control
line retainer arm is released from the docking assembly, the docking assembly may
deploy, or cause to be deployed, one or more blocking members to prevent reengagement
of the pipe engagement apparatus until the control line retainer arm is again releasably
coupled to the docking assembly. In one embodiment, when the control line retainer
arm couples to the docking assembly, the docking assembly may automatically disable
or retract the one or more blocking members to again permit the pipe engagement apparatus
to engage and support the pipe string.
[0015] In one embodiment, the movement of the control line retainer arm of the control line
positioning apparatus may be by rotation and/or translation, and the control line
retainer arm may be movable between the removed position, to restrain the control
lines from entering the operating zone of the pipe engagement apparatus, and a raised
position to position the control lines along a portion of the pipe string to facilitate
the application of a clamp. In one embodiment, the movement of the control line retainer
arm may, for example, be generated by simultaneous translation and rotation of the
control line retainer arm within a common plane as the control retainer arm is raised
from the removed position to the raised position, or as the retainer arm is lowered
from the raised position to the removed position. The translation and/or rotation
of the retainer arm may be driven by a drive member, for example, a cylinder, coupled
to the control line retainer arm.
[0016] In one embodiment, the control line positioning apparatus may comprise a positionable
control line retainer arm supporting a control line retainer assembly. The control
line retainer assembly may comprise a control line retainer that may slidably or rollably
engage one or more control lines so that the control lines can be positioned proximal
to the pipe string by raising the control line retainer arm from the removed position
to the raised position. The one or more control lines may be fed to the control line
retainer assembly coupled to the control line retainer arm from a control line reel
that is positioned remote to the control line positioning apparatus. In one embodiment,
a control line reel may be disposed above, on or adjacent to the rig floor and generally
lateral to the pipe string. In another embodiment, a control line reel may be disposed
underneath the rig floor within a sub-space. Optionally, the control line retainer
comprises rolling members, such as rollers or sheaves, and the control lines may be
routed or threaded over the rollers or sheaves to rotatably couple the control lines
to the control line retainer arm, and to feed the control lines to the control line
retainer that is positionable by movement of the control line retainer arm.
[0017] Once positioned along the pipe string by the control line positioning apparatus,
the control lines may be secured to the pipe string using fasteners, such as clamps,
sleeves, bands, clips, ties or other fasteners, and these fasteners may be applied
or installed by rig personnel or by an automatic fastener installing machine. In one
embodiment, a fastener installing machine may be coupled to and supported by the control
line positioning apparatus and automatically deployed to install a fastener to clamp
control lines to the pipe string when the control line retainer arm is in the raised
position.
[0018] In one embodiment of the control line positioning method and the apparatus, for example,
when the slips of a spider engage and grip a pipe string, or when the halves of the
CLS landing spear close to surround and support the pipe string, the control line
retainer arm of the control line positioning apparatus is in the removed position
to position and restrain the control lines from entering the operating zone of the
pipe slips of the spider, or from entering the operating zone of the halves of the
CLS landing spear, to protect the control lines from being pinched, crushed or otherwise
damaged. In one embodiment, the control line positioning apparatus may be automatically
disabled. For example, the control line positioning apparatus may be disabled during
engagement of the pipe engaging apparatus by releasably coupling the control line
retainer arm to a docking assembly adjacent to the pipe engaging apparatus to prevent
inadvertent movement of the control line retainer arm to the raised position and to
prevent the resulting movement of the control lines from entering the operating zone
of the pipe engaging apparatus. In an alternate embodiment, the pipe engaging apparatus
may be disabled from engaging the pipe string when the control line retainer arm is
not in the removed position. For example, the slips of a spider may be disabled from
engaging the pipe string, or the halves of the CLS landing spear may be disabled from
closing to surround the pipe string, when the control line retainer arm of the control
line positioning apparatus is not in the removed position. These safeguards prevent
damage to control lines by engagement of the slips of the spider or by closure of
the halves of the CLS landing spear.
[0019] In one embodiment of the control line positioning apparatus for use with a spider,
the retainer arm of the control line positioning apparatus positions the control lines
along a portion of the pipe string and at a radial position that is generally opposite
the center slip of a three-unit slip assembly. In a three-unit slip assembly, a center
slip, a right slip and a left slip each comprise a gripping face having a generally
arcuate gripping surface that generally conforms to the curvature of the exterior
of the pipe string. The right slip and the left slip may be hingedly coupled to the
right side and the left side, respectively, of the center slip so as to form a generally
annular slip assembly when the right and left slips are rotated to surround the pipe
string. When the spider is disengaged, the load of the pipe string is transferred
to the elevator assembly, and the center slip is manipulated up from its gripping
position within the tapered bowl of the spider, and simultaneously pulled radially
away from the pipe string. As the right slip and left slip follow the center slip,
each of the right slip and the left slip hinge and rotate away from the annular position
relative to the center slip, and toward a lateral, open and disengaged position relative
to the center slip. It should be understood that the number of slips in the slip assembly
may be varied without a substantial change in the manner of use or mode of operation
of the slip assembly within the context of the use and operation of the control line
positioning apparatus.
[0020] In one embodiment, the movement of the control line retainer arm of the control line
positioning apparatus between the removed position and the raised position is provided
by operation of a mechanical linkage comprising the control line retainer arm having
a first end and a second end, a track that engages a follower that is coupled to the
retainer arm intermediate the first end and the second end, a stabilizer coupled to
the control line retainer arm and a drive member to drive the follower along the path
of the track. The path of the track may be generally adapted to produce, at the control
line retainer assembly that is coupled to the second end of the control line retainer
arm, a resulting path terminating at a removed position proximate the pipe engaging
apparatus at or near a lower end of the track, and terminating at a raised position
that is proximate the pipe string and generally above the pipe engaging apparatus
at or near an upper end of the track.
[0021] In another aspect, the present disclosure comprises a rig floor-mounted pathway comprising
a protectable control line feed channel. In one embodiment, the rig floor-mounted
pathway comprises a channel cover, a first cover support and a generally parallel
second cover support. The cover and the first and second cover supports may each be
generally elongate, each having a first end disposed proximate a control line positioning
apparatus and a second end distal the control line positioning apparatus. In one embodiment,
the channel cover may be hingedly coupled to one of the first cover support or the
second cover support, and the channel cover may be pivotable between an open position
to provide access to the control line feed channel, and a closed position to close
and protect the control line feed channel.
[0022] In one embodiment, the first and/or the second cover supports each may comprise a
generally triangular cross-section and positioned one relative to the other to dispose
an acutely angled portion of the cover support outboard to the channel, and to disposed
a substantially right-angled or a substantially angled portion of the cover support
adjacent to the channel defined between the first and the second cover supports. This
arrangement of the cover supports and the triangular cross-sections thereof provides
a ramp-like structure on both sides of the rig floor-mounted pathway, each generally
parallel to the channel, to facilitate unimpaired movement of equipment or personnel
over the pathway. The cover supports may comprise highly visible colors and/or treaded
surfaces to provide favorable traction for personnel that may walk on the pathway.
[0023] In one embodiment, the rig floor-mounted pathway may comprise a bend portion to receive
a control line feed and redirect one or more control lines received at an inlet to
the bend portion to assume a new direction upon exiting the bend portion through an
outlet. The bend portion may comprise a plurality of rolling members, such as rollers,
arranged in one or more arcuate patterns to prevent exceeding a desired minimum bend
radius as the control lines are redirected by the bend portion. In one embodiment,
the bend portion may be coupled to a scale, a strain gauge, a load cell or other force
measuring device to measure the force applied to the bend portion, or to a component
of the bend portion, and the measured force may be used to determine the tension in
one or more of the control lines redirected by the bend portion. In one embodiment,
the force may be measured and the tension in one or more control lines may be determined
using an algorithm that calculates the tension, and the tension in the one or more
control lines may be compared to one or more maximum recommended tension values to
generate a warning, alarm, or to interrupt operation of the control line positioning
apparatus fed by the pathway until the cause of the excessive control line tension
can be investigated and remedied.
[0024] In one embodiment, a control line positioning apparatus may provide a base, a control
line retainer arm having a first end and a second end, a drive member to move the
control line retainer arm between a removed position and a raised position, and an
ascending control line pathway cooperating with the control line retainer arm and
having an inlet to the ascending pathway proximate the base and an outlet spaced-apart
from the inlet and generally above or proximate to the retainer arm. The ascending
pathway may further comprise one or more rolling members to engage and redirect one
or more control lines fed into the inlet, for example, from a rig floor-mounted pathway
or from an aperture through the rig floor providing access to a sub-space beneath
the rig floor. The rolling members of the ascending pathway are spaced apart one from
the others to redirect the one or more control lines along the rolling members without
exceeding the minimum bend radius of the one or more control lines, and the rolling
members are positioned to feed the one or more control lines from the outlet of the
ascending pathway and to the control line retainer assembly coupled to the second
end of the control line retainer arm when in the control line retainer arm is in the
removed position, the raised position, and all positions therebetween.
[0025] In one embodiment, an apparatus to cut a control line may include a movable cutting
apparatus having a cutting member attached thereto, in which the movable cutting apparatus
is configured to move the cutting member between a retracted position and a deployed
position. The cutting member of the movable cutting apparatus is configured to engage
and cut the control line in the deployed position of the cutting member.
[0026] In one embodiment, a method to cut a control line may include providing a movable
cutting apparatus having a cutting member attached thereto and disposed adjacent to

BRIEF DESCRIPTION OF DRAWINGS
[0055] Features of the present disclosure will become more apparent from the following description
in conjunction with the accompanying drawings.
Fig. 1 is an elevation view of one embodiment of the control line positioning apparatus
having a control line retainer assembly coupled to the second end of a rotational
and translational control line retainer arm, the control line retainer assembly positioned
adjacent to, and slightly elevated from, a spider.
Fig. 2 is the control line positioning apparatus of Fig. 1 after the control line
retainer arm and the control line retainer assembly thereon are moved, using a drive
member, to a position proximate the pipe string and further above the spider by rotation
and translation of the control line retainer arm.
Fig. 3 is the control line positioning apparatus of Fig. 2 after the control line
retainer arm and the control line retainer assembly are moved, using the drive member,
to a position proximate the pipe string and still further above the spider by further
rotation and translation of the retainer arm.
Fig. 4 is the control line positioning apparatus of Fig. 3 after the control line
retainer arm and the control line retainer assembly thereon are moved, using the drive
member, to a raised position proximate the pipe string and still further above the
spider by further rotation and translation of the control line retainer arm, and after
an optional auxiliary pusher arm movably coupled to the control line retainer arm
is deployed to position the control lines along a portion of the pipe string to facilitate
clamping of the control line to the portion of the pipe string above the spider.
Fig. 5 is a perspective view of the control line positioning apparatus of Fig. 4 after
a clamp is installed to secure the control line to the portion of the pipe string
above the spider. Also shown in Fig. 5, but not present in Figs. 1 to 4, is one embodiment
of a docking assembly to secure the control line retainer arm in a removed position.
Fig. 6A is a perspective view of one embodiment of a control line retainer assembly
coupled to the second end of the control line retainer arm of a control line positioning
apparatus. The control line retainer assembly of Fig. 6A comprises a docking member
positioned adjacent to one embodiment of a docking assembly that may be disposed adjacent
a pipe engagement apparatus and releasably coupled to the control line retainer arm.
Fig. 6B is a perspective view of the control line retainer arm of Fig. 6A after the
control line retainer arm and the docking member thereon are lowered to engage the
docking assembly and releasably couple to the docking assembly, and the docking member
of the control line retainer assembly is releasably captured within a pivotable docking
wheel of the docking assembly. Fig. 6B shows the docking wheel coupled to the docking
member and blocked from rotation back to its open position to immobilize the control
line retainer arm.
Fig. 7A is an elevational cross-section view of one embodiment of a spider that may
be used to engage and grip a pipe string, and to cooperate with a position sensor
that senses the movement of the control line retainer arm to a removed position to
restrain the control lines coupled to the control line retainer arm from entering
the zone of operation of the spider. The position sensor may be used to prevent the
slips of the spider from engaging a pipe string (not shown in Fig. 7A) until the control
line retainer arm of the control line positioning apparatus is in the removed position.
Fig. 7B is the elevational cross-section view of Fig. 7A after the control line retainer
arm has been moved to the removed position to activate the position sensor, and after
the spider is enabled to engage and support the pipe string (not shown in Fig. 7A).
The activation of the position sensor may automatically enable engagement of the spider
by, for example, opening a valve to supply pressurized fluid to disable a blocking
member, such as a cylinder.

spear around the pipe string until the position sensor detects the movement of the
control line retainer arm to the removed position.
Fig. 8B is the perspective view of Fig. 8A after the control line retainer arm is
moved to the removed position and releasably coupled to the docking assembly. The
movement of the control line retainer arm to the removed position to restrain the
control lines from entering the operating zone of the CLS landing spear, and the releasable
coupling of the control line retainer arm with the docking assembly, automatically
withdraws the blocking member to a retracted position to permit pivotal closure of
the halves of the CLS landing spear around the pipe string.
Fig. 9A is a perspective view of one embodiment of an automatic safety latch to allow

DETAILED DESCRIPTION
[0056] Specific embodiments of the present disclosure will now be described in detail with
reference to the accompanying figures. Like elements in the various figures may be
denoted by like reference numerals for consistency. Further, in the following detailed
description of embodiments of the present disclosure, numerous specific details are
set forth in order to provide a more thorough understanding of the present disclosure.
However, it will be apparent to one of ordinary skill in the art that the embodiments
disclosed herein may be practiced without these specific details. In other instances,
well-known features have not been described in detail to avoid unnecessarily complicating
the description.
[0057] Furthermore, those having ordinary skill in the art will appreciate that when describing
connecting or coupling a first element to a second element, it is understood that
connecting and coupling may be either directly connecting or coupling the first element
to the second element, or indirectly connecting or coupling the first element to the
second element. For example, a first element may be directly connected to a second
element, such as by having the first element and the second element in direct contact
with each other, or a first element may be indirectly connected to a second element,
such as by having a third element, and/or additional elements, connected between the
first and second elements.
[0058] In one embodiment, the present disclosure provides a control line positioning method
and apparatus to position one or more generally continuous control lines along a portion
of a pipe string to facilitate securing the control lines to the pipe string as it
is made-up and run into a borehole from a rig. The method may comprise the steps of
coupling one or more control lines to a control line retainer arm that is movable
by a drive member between a raised position and a removed position that restrains
the control lines from entering the operating zone of a pipe engaging apparatus. The
method may additionally comprise the step of releasably coupling the control line
retainer arm in the removed position to prevent the retainer arm from being moved
to the raised position until the pipe engaging apparatus is in the open and disengaged
condition. The method may further comprise the steps of releasing the control line
retainer arm from the coupled position, raising the control line retainer arm to position
the control lines along a portion of the pipe string above the pipe engagement apparatus,
and clamping the control lines to the pipe string. The method may further comprise
the steps of lowering the pipe string and the control lines into the borehole, returning
the control line retainer arm to the removed position, and closing the pipe engaging
apparatus to engage and support the pipe string in the borehole.
[0059] In another embodiment, the present disclosure provides a control line positioning
method and apparatus to position one or more control lines along a portion of a pipe
string above a pipe engaging apparatus to be clamped to the pipe string as the pipe
string is made-up and run into a borehole, and to protect the control lines from being
pinched or crushed by closure of the pipe engaging apparatus used to engage and support
the pipe string within the borehole. The apparatus may comprise a base, a control
line retainer arm movable between a raised position and a removed position to restrain
the control lines from entering the operating zone of the pipe engaging apparatus,
and a control line retainer assembly having a control line retainer coupled to and
movable by the control line retainer arm. In one embodiment, the apparatus may further
comprise a docking member to releasably couple to a docking assembly disposed adjacent
to the pipe engaging apparatus. In another embodiment, the apparatus may further comprise
a receiving member to be removably received in a receiving assembly disposed adjacent
to the pipe engaging apparatus. The drive member of the apparatus may be used to drive
the control line retainer arm to the raised position to position control lines along
a portion of the pipe string above the pipe engaging apparatus to be clamped to the
pipe string. After a clamp is applied to secure the control lines to the pipe string,
the pipe string and the control lines may be lowered into the borehole to position
the clamp below the pipe engaging apparatus, the control line retainer arm may be
moved to the removed position, and the load of the pipe string may then be transferred
back from the elevator assembly to the pipe engaging apparatus. The method and the
apparatus will protect the control lines from damage that may result from pinching
or crushing between pipe slips of a spider, or between a pipe slip and the exterior
surface of the pipe string, or between the halves of a CLS landing spear in a CLS
pipe engaging apparatus.
[0060] In one embodiment, a control line positioning apparatus comprises a control line
retainer arm, positionable between a raised position and a removed position, and movably
supporting a control line retainer assembly thereon. The control line retainer assembly
may comprise a control line retainer that slidably or rollably engages one or more
control lines fed to the pipe string through or over the control line retainer assembly.
In one embodiment, the control line retainer assembly may further comprise a docking
member that can be releasably coupled in a docking assembly disposed adjacent to the
pipe engaging apparatus when the control line retainer apparatus is in the removed
position.
[0061] In one embodiment, the control line positioning apparatus may be automatically disabled
from moving the control line retainer arm to the raised position, and from thereby
positioning the control lines along a portion of the pipe string above the pipe engaging
apparatus, when the pipe engaging apparatus is engaged and supporting the pipe string
within the borehole, thereby requiring that the pipe string be supported from an elevator
assembly movably disposed above the rig floor and above the pipe engaging apparatus.
For example, the control line positioning apparatus may be disabled when the slips
of a spider are engaged to support the pipe string in the borehole. In an alternate
embodiment, the pipe engaging apparatus may be disabled from engaging and supporting
the pipe string when the control line positioning apparatus is not in a removed position
restraining the control lines from entering the operating zone of the pipe engaging
apparatus. For example, the slips of a pipe engaging apparatus supported on or in
a rig floor may be disabled from engaging and supporting a pipe string in a borehole
when the control line retainer arm of the control line positioning apparatus is raised
to position control lines along a portion of the pipe string above the pipe engaging
apparatus.
[0062] In one embodiment of the control line positioning apparatus that is adapted to cooperate
with a spider, the control line retainer arm may be movable to position one or more
control lines along a portion of the pipe string above the pipe engaging apparatus
and at a position generally radially opposite the center slip of a three-unit slip
assembly. In a three-unit slip assembly, a center slip, a right slip and a left slip
each define, along each gripping face, an arcuate gripping surface that generally
conforms to the exterior contour of the pipe string. The right slip and the left slip
are hingedly coupled to the right side and the left side, respectively, of the center
slip so as to form a generally annular slip assembly when the right and left slips
are rotated to the gripping positions relative to the center slip. When the spider
is to be disengaged, the load of the pipe string may be transferred to an elevator
assembly movably disposed above the spider, and the center slip may be manipulated
up from its gripping position within the tapered bowl of the spider and radially away
from the pipe string. As the right and left slips follow, each hinges away from its
annular position relative to the center slip and toward a open and disengaged position.
It should be understood that the number of slips in the slip assembly may be varied
without substantial change in the manner of use or operation of the slip assembly
within the context of the use and operation of the control line positioning apparatus.
[0063] In one embodiment, the positioning of the control line retainer arm of the control
line positioning apparatus between the removed position and the raised position is
provided by rotation of the control line retainer arm. In another embodiment, the
positioning of the control line retainer arm of the control line positioning apparatus
between the raised position and the removed position is provided by translation of
the control line retainer arm, either vertical, horizontal or both. A control line
retainer assembly may be coupled to the control line retainer arm to slidably or rollably
couple one or more control lines to the control line retainer arm so that the control
lines can be fed into the borehole along with the pipe string, and the control lines
may also be positioned between the raised position and the removed position by rotational
or translational movement of the arm. It should be understood that a rotationally
movable control line retainer arm and/or a translatably movable control line retainer
arm may also extend, for example, by use of an extendable cylinder or a telescoping
cylinder, to vary its length in order to position the control line retainer arm in
the removed position to restrain the control lines slidably or rollably coupled thereto
from entering the operating zone of a pipe engaging apparatus.
[0064] In one embodiment, the positioning of the control line retainer arm of the control
line positioning apparatus between the removed position and the raised position is
provided by simultaneous rotation and translation of the control line retainer arm.
In this embodiment, the control line positioning apparatus may comprise a base, a
track supported on the base to engage a follower driven by a drive member along a
path of the track, a stabilizer coupled to the base at a first end and coupled to
a retainer arm at a second end, the control line retainer arm coupled to the follower
and positionable by the drive member, as restrained by the track and follower, and
the stabilizer, between a removed position and a raised position. The follower may
be moved along the path of the track by, for example, a cylinder or other source of
mechanical, hydraulic or pneumatic power.
[0065] In one embodiment, a control line retainer assembly may be coupled to the control
line retainer arm and may comprise a control line retainer to slidably or rollably
couple one or more control lines to the control line retainer arm so that the control
lines may be positioned by movement of the control line retainer arm. In embodiments
of the control line positioning apparatus that cooperate with a docking assembly or
a control line retainer arm position sensor to implement a safety interlock to prevent
damage to the control lines from closure of the pipe engaging apparatus, the control
line retainer assembly may comprise a docking member that can be releasably captured
by a docking assembly, or it may comprise a position sensor that can detect movement
of the control line retainer assembly to its removed position.
[0066] Fig. 1 is an elevation view of one embodiment of the control line positioning apparatus
10 having a control line retainer assembly 50 coupled to the second end 30B of a rotatable
and translatable control line retainer arm 30, the control line retainer assembly
50 positioned adjacent to a pipe string 80 and proximate a pipe engaging apparatus
70. The pipe engaging apparatus 70 shown in Fig. 1 is a spider that is supported by
the rig floor 8 generally over an aperture 75 in the rig floor 8, and an elevator
assembly 82 can be engaged to support the pipe string 80 so that the pipe engaging
apparatus 70 may be disengaged. The control line retainer assembly 50 of Fig. 1 may
comprise a plurality of rolling members to rollably engage a control line 90 as it
is moved by the control line retainer arm to position the control line 90. It should
be understood that a single control line 90 is illustrated in many of the appended
drawings, but a plurality of control lines can be positioned in a generally parallel
relationship by the control line positioning apparatus 10.
[0067] In the embodiment of the control line retainer assembly 50 shown in Fig. 1, a primary
roller 51 rotatable on a first axle 51a engages the control line 90. Optionally, a
generally "L"-shaped protective shield 53 may be rotatably coupled to the first axle
51a to support a secondary roller 52 rotatable on a second axle 52a and spaced apart
from the primary roller 51 to accommodate one or more control lines 90 there between.
It should be understood that the primary roller 51 and, optionally, the secondary
roller 52 may each comprise one or more grooves, ridges, shoulders or rims to position
and retain control lines in a generally predetermined position along the roller and/or
in a parallel relationship with other control lines as the control lines are fed through
the control line retainer assembly 50 during movement of the control line retainer
arm 30 relative to the control line 90.
[0068] Optionally, control line retainer assembly 50 may be hinged to open so that control
lines can be introduced and retained within or removed from the control line retainer
assembly 50. In one embodiment to be discussed later in connection with Figs. 5-6B,
8A-8B and 10, the control line retainer 50 may further comprise a receiving member
or a docking member that may be removably received or releasably coupled, respectively,
to a receiving assembly or a docking assembly, respectively. While no receiving assembly
or docking assembly is shown in Figs. 1 to 4, it should be noted that, in one embodiment
of a receiving member and/or a docking member, a protruding locking pin 55 may protrude
outwardly from the control line retainer assembly 50 to serve this purpose.
[0069] The pipe engaging apparatus, which in Fig. 1 is a spider 70, comprises a tapered
bowl 71 movably receiving a set of pipe slips 72 that can be engaged with the exterior
surface of the pipe string 80 to support the pipe string 80 within the borehole 5
below the spider 70.
[0070] The embodiment of the control line positioning apparatus 10 shown in Fig. 1 comprises
a base 12 pivotally coupled to the first end 24A of a stabilizer 24 to provide rotation
of the stabilizer 24 within an angular range and within a generally vertical plane
within the plane of elevation view of Fig. 1. The base 12 also supports a frame 62
having a track 69 with a lower end 69A and an upper end 69B. The path of the track
69 shown in Fig. 1 may be generally characterized as upwardly sloped at every position
along the path of the track 69 between the lower end 69A and upper end 69B or, alternately,
the track 69 may be characterized as downwardly sloped at every position along the
path of the track 69 between the upper end 69B and lower end 69A. The track 69 shown
in Fig. 1 is adapted to slidably or rollably engage a follower 39 coupled through
truss members 36, 37 to the control line retainer arm 30 and imposing on the follower
39 a pattern of movement influenced or determined by the path of the track 69. The
frame 62 and the track 69 in Fig. 1 are supported in a generally fixed position relative
to the base 12 by a support 61 extending upwardly from the base 12.
[0071] The second end 24B (not shown in Fig. 1 - see Fig. 2) of the stabilizer 24 shown
in Fig. 1 is pivotally coupled to a first end 30A (not shown in Fig. 1 - see Fig.
2) of a control line retainer arm 30, and the retainer arm assembly 50 is coupled
to the second end 30B of the retainer arm 30, with the control line retainer arm 30
coupled to the follower 39 through truss members 36, 37 at a position intermediate
the first end 30A and the second end 30B. It should be understood that the retainer
arm 30 of the control line positioning apparatus 10 in Fig. 1, like the stabilizer
arm 24, may rotate within the plane of the drawing, but unlike the stabilizer arm
24, the retainer arm 30 shown in Fig. 1 may also translate within the same plane during
operation of the control line positioning apparatus 10 as disclosed in connection
with Figs. 1 to 4.
[0072] Also shown in Fig. 1 is an auxiliary arm 40 that may deploy, as shown in Figs. 4
and 5, to position the control line 90 along a portion of the pipe string 80 to facilitate
clamping (not shown in Fig. 1 - see Fig. 5) to secure the control line 90 to the pipe
string 80. The auxiliary arm 40 in Fig. 1 is pivotally coupled to the retainer arm
30 by auxiliary pusher arm stabilizers 47, 48 and the auxiliary arm 40 may be retracted
(as shown in Fig. 1) or extended (as shown in Fig. 4) by auxiliary pusher arm cylinder
46.
[0073] The control line positioning apparatus 10 of Fig. 1 further comprises a drive member
13 having a feed line of pressurized fluid 18 to move the control line retainer arm
30 between a removed position and a raised position, as will be discussed in relation
to Figs. 2-4. The traveling end 17 of the rod 14 is pivotally coupled to the follower
39 of the retainer arm 30 to guide the follower 39 along the path of the track 69
upon extension and retraction of rod 14 from and within cylinder 13. The cylinder
13 in Fig. 1 is pivotally coupled to base 12 at cylinder pivot 15 to permit the cylinder
13 to pivot within a limited angular range in the plane of the drawing of Fig. 1.
[0074] Fig. 2 is the control line positioning apparatus 10 of Fig. 1 after the retainer
arm 30 and the control line retainer assembly 50 are raised, by extension of drive
member 13, to position the retainer assembly 50 adjacent to the pipe string 80 and
generally further above the pipe engaging apparatus 70 as compared to the position
shown in Fig. 1. The movement of the control line retainer assembly 50 to the position
shown in Fig. 2, as compared to the position in Fig. 1, results from simultaneous
rotation (in a counterclockwise direction) and translation (to the left in Fig. 1)
of the control line retainer arm 30. Fig. 2 shows the cylinder rod 14 extended further
from the cylinder 13 due to force applied to the rod 14 by pressurized fluid supplied
to the cylinder 13 through fluid conduit 18, and also pivotal rotation of the cylinder
13 about pivot 15 (in a counterclockwise direction) as the cylinder rod 14 extends
to drive the traveling end 17 and the follower 39 upwardly along the path of track
69. The stabilizer 24 has also pivoted (in a counterclockwise direction) from its
position in Fig. 1.
[0075] Fig. 3 is the elevation view of Fig. 2 after the control line retainer assembly 50
is moved further by extension of drive member 13 to a position generally adjacent
the pipe string 80 and still further above the pipe engaging apparatus 70. The cylinder
13 moves the travelling end 17 and the follower 39 further along the path of the track
69 towards the upper end 69B. It should be noted that the stabilizer 24, which initially
rotated counterclockwise (from the position in Fig. 1 to the position in Fig. 2) has
reversed its direction of rotation due to the change in horizontal component of the
direction of the track 69, and that the extreme counterclockwise position of the stabilizer
24 occurred at a point intermediate the positions shown in Figs. 2 and 3.
[0076] Fig. 4 is the elevation view of the control line positioning apparatus 10 of Fig.
3 after the control line retainer assembly 50 is moved further by extension of drive
member 13 to a raised position generally adjacent to and proximate the pipe string
80, and further above the pipe engaging apparatus 70 as compared to Fig. 3, and after
an optional auxiliary pusher arm 40 is deployed by extension of auxiliary pusher arm
cylinder 46 to position the control line 90 along a portion of the pipe string 80
above the pipe engaging apparatus 70 to facilitate clamping to secure the control
line 90 to the pipe string 80. The follower 39 is shown to be moved, as compared to
the position in Fig. 3, further along the path of the track 69 by further extension
of the rod 14 from the cylinder 13. It should be understood that the curvilinear path
of the track 69 enables the control line positioning apparatus 10 of Fig. 4 to be
used to position control lines against or proximate to a pipe string with a range
of distances separating the base 12 of the apparatus 10 from the pipe engaging apparatus
70 since the follower 39 can be, if necessary to achieve proper control line positioning,
positioned further along the path of the track 69 towards the upper end 69B. It should
also be understood that this flexibility enables the control line positioning apparatus
10 to be used to position control lines against or proximate to a range of diameters
of pipe string given a constant distance separating the base 12 from the pipe engaging
apparatus 70. With the distance between the base 12 of the control line positioning
apparatus 10 and the pipe engaging apparatus 70 and the diameter of the pipe string
80 shown in Figs. 1 to 4, the position of the control line positioning apparatus 10
shown in Fig. 4 represents the fully-deployed configuration of the control line positioning
apparatus 10 for this specific configuration, but the raised position of a given control
line positioning apparatus 10 may vary according to these parameters. It should be
further understood that the shapes and configurations of the various components of
the control line positioning apparatus 10, such as, for example, the length and pivot
location of the stabilizer 24, the angle, length and position of the follower 39 of
the control line retainer arm 30, the position of the follower 39 on the retainer
arm 30, the length and pivot position of the cylinder 13, and the shape and location
of the track 69 within frame 62, to name a few, as well as the relative spatial relationships
of these components, one relative to the others, will influence the raised position
and the removed position shown in Figs. 4 and 1, respectively, as well as all intermediate
positions, such as those shown in Figs. 2 and 3.
[0077] It should be noted that the pipe string 80 shown in Figs. 1 to 4 is supported by
an elevator assembly 82 coupled to the pipe string 80 and, in turn, supported from
above the view of these figures by bails 83, a block and draw works (not shown in
Figs. 1 to 4), as is well known in the art. The pipe string 80 must remain supported
from the string elevator above at all times until the slips 72 of the spider 70 are
released to seat in the tapered bowl 71 and to engage and support the pipe string
80 within the borehole.
[0078] Fig. 5 is a perspective view of the embodiment of the control line positioning apparatus
10 shown in Fig. 4 after a clamp 88 is installed to secure the control line 90 to
the pipe string 80. Fig. 5 reveals a generally bipartite structure of the embodiment
of the control line retainer arm 30, frame support 61, frame 62, track 69 and follower
39 shown in Fig. 5, and a generally unitary and centered stabilizer 24, cylinder 13,
and auxiliary pusher arm cylinder 46, all generally intermediate the bipartite members.
It should be understood that a wide variety of each of these components can be designed
without departing from the scope of the present disclosure, and that the illustrations
in Figs. 1-5 are of but one embodiment of the control line positioning apparatus 10.
[0079] In one embodiment of the control line positioning apparatus 10, the control line
retainer arm can be moved to its removed position and releasably coupled to a docking
assembly adjacent the pipe engaging apparatus that cooperates with the pipe engaging
apparatus to prevent inadvertent closure of the pipe engaging apparatus if the control
line retainer assembly is not coupled to the docking assembly, to prevent inadvertent
moving of the control line retainer arm away from the removed position while the pipe
engaging apparatus is in the closed position, or both. It should be understood that
a docking assembly that cooperates with the pipe engaging apparatus to prevent one
or both of these actions may be used along with a control line positioning apparatus
of the present disclosure. Similarly, in one embodiment of the control line positioning
apparatus 10, the control line retainer arm can be moved to its removed position and
removably received in or at a receiving assembly adjacent the pipe engaging apparatus
that cooperates with the pipe engaging apparatus to prevent inadvertent closure of
the pipe engaging apparatus if the control line retainer assembly is not received
in or at the receiving assembly, to prevent inadvertent moving of the control line
retainer arm away from the removed position while the pipe engaging apparatus is in
the closed position, or both. It should be understood that a docking assembly or a
receiving assembly that cooperates with the pipe engaging apparatus to prevent one
or both of these actions may be used along with a control line positioning apparatus
of the present disclosure.
[0080] Fig. 5 illustrates the use of one embodiment of a docking assembly 150 with the control
line positioning apparatus 10 illustrated in Figs. 1 to 4, the docking assembly 150
comprising a rotating wheel or a Geneva wheel 155 pivotally coupled to rotate between
an open position (as shown in Fig. 6A) to receive a docking member 55 protruding from
the control line retainer assembly 50 on the control line retainer arm 30, and a closed
position (as shown in Fig. 6B) to secure the docking member 55 within the docking
assembly 150 and thereby couple the control line retainer arm 30 in the removed position.
The rotating wheel or Geneva wheel 155 shown in Fig. 6A pivots about a wheel pivot
156 adjacent to a stationary receiving slot 166 of the docking assembly 150 and may
be spring biased (spring not shown in Fig. 6A) towards its open position shown in
Fig. 6A. The position of the control line retainer arm 30 shown in Fig. 6A is slightly
elevated above the docking assembly. The docking member 55 of the control line retainer
assembly 50 is generally vertically aligned with the stationary receiving slot 166
of the docking assembly 150 so that, as the control line retainer arm 30 is lowered
by gravity or by operation of the cylinder 13 (not shown in Fig. 6A - see Figs. 1
to 4) from the position in Fig. 6A, the docking member 55 is received generally simultaneously
into the receiving slot 166 and also into the slot 159 of the rotating wheel or Geneva
wheel 155 to rotate the wheel 155 clockwise about its pivot 156 as the docking member
55 is moved towards the bottom of the stationary receiving slot 166.
[0081] It should be understood that, as the control line retainer arm 30 is moved from the
position shown in Fig. 6A to the coupled position shown in Fig. 6B, the protective
shield 53 control line retainer assembly 50 may be received into a space intermediate
the pipe string 80 (not shown in Fig. 6A - see Figs. 1 to 4) and the docking assembly
150 to shield the portion of the control line 90 generally below the primary roller
51 from the moving components in the operating zone of the pipe engaging apparatus
70 (not shown in Fig. 6A - see Figs. 1 to 4).
[0082] The movement of the rotating wheel or Geneva wheel 155 from its open position shown
in Fig. 6A to its coupled and closed position shown in Fig. 6B may, in one embodiment,
be sensed by a toggle sensor 165 pivotally coupled and positioned adjacent to the
rotating wheel or Geneva wheel 155 so that rotation of the wheel 155 to its closed
position (as shown in Fig. 6B) toggles the toggle sensor 165 to, for example, open
a valve to actuate a wheel blocker cylinder 158 to reposition wheel blocker 157 into
the path of the rotating wheel or Geneva wheel 155 to prevent the wheel 155 from returning
to its open position and from releasing the control line retainer arm 30 from the
removed position corresponding to the coupling with the docking assembly 150.
[0083] Fig. 6B is the perspective view of Fig. 6B after the docking member 55 is received
into the stationary receiving slot 166 to rotate the rotating wheel or Geneva wheel
155 from the open position to its closed position, and after the wheel blocking cylinder
158 is actuated by depression of the toggle sensor 165 to reposition the wheel blocker
157 to secure the wheel 155 in the closed position. In one embodiment, the wheel blocking
cylinder 158 may be spring-biased to the position shown in Fig. 6B to require positive
fluid pressure to remove the wheel blocker 157 from the path of the wheel 155 to release
the retainer arm 30 from the docking assembly 150.
[0084] In one embodiment, the movement of the wheel blocker 157 into the path of the rotating
wheel or Geneva wheel 155 may correspond to the release of a blocking member in the
pipe engaging apparatus 70 to enable the pipe engaging apparatus to move from an open
position to a closed position to engage and support the pipe string 80. For example,
Fig. 7A is an elevation cross-section view of one embodiment of a spider 70 to releasably
engage and grip a pipe string 80 (not shown in Fig. 7A), and to cooperate with the
position sensor 174 to prevent the slips 73 of the spider 70 from engaging a pipe
string until, for example, a position sensor 174 detects that the control line positioning
arm 30 is in the removed position. Fig. 7A shows a slip positioning linkage 170 to
position a set of slips 73 within the tapered bowl 71 of a spider 70. The slip linkage
170 may be powered by a cylinder (not shown) to retract the slips 73 from the tapered
bowl 71 to the removed position of Fig. 7A, where the slips 73 are captured by a blocking
member, such as a slip retainer hook 172, to prevent inadvertent engagement of the
slips 73 with the pipe string 80 when the control line retainer arm 30 (see Figs.
6A and 6B) is not in the removed position. Once the slips 73 are captured in the removed
position by the slip retainer hook 172, as shown in Fig. 7A, the slip retainer hook
172 may be held in the removed position by hook release cylinder 165 and, in one embodiment,
may not release slips 73 to engage pipe string 80 until position sensor 174 is depressed
by the control line retainer arm 30 (not shown in Fig. 7A - see Fig. 7B) to unlock
the slip retainer hook 172.
[0085] As shown in Fig. 7A, a spring-biased slip release cylinder 165 may be coupled to
a spring-biased slip retainer hook 172 to retain the slips 73 of spider 70 in the
open and disengaged position until fluid pressure is provided to slip release cylinder
165 to override the spring-bias, pivot the slip retainer hook 172 and to thereby release
the slips 73 of the spider 70 to engage and close on the portion of the pipe string
within the tapered bowl of the spider 70.
[0086] Fig. 7B is the elevation cross-section view of Fig. 7A after control line retainer
arm 30 engages the position sensor 174. The activation of the position sensor 174
may automatically enable the spider 70 by, for example, opening a valve to supply
pressurized fluid to the hook release cylinder 173 to override the spring bias and
to release the slip retainer hook 172 and to release the slips 73 to enter the tapered
bowl 71. It should be understood that other effective position sensors may be used
to prevent engagement of the pipe engaging apparatus until the control line retainer
arm is detected in its removed position to restrain the control lines from entering
the operating zone of the pipe engaging apparatus.
[0087] Fig. 8A is a perspective view of one embodiment of a control line retainer assembly
50 coupled to the second end 30B of control line retainer arm 30 of a control line
positioning apparatus (not shown in its entirety). The control line retainer assembly
50 of Fig. 8A is docked with an alternate embodiment of a docking assembly 150 adjacent
to a CLS landing spear 100 in an open position. The docking assembly 150 shown in
Fig. 8A deploys a rotatable blocking member 120 to protect the control line 90 by
obstructing pivotal closure of the halves 102 of the CLS landing spear 100 about hinges
108 to surround pipe string.
[0088] Fig. 8B is the perspective view of Fig. 8A after the docking assembly 150 is releasably
coupled to the control line retainer arm 30 of the control line positioning apparatus.
In the embodiment of Fig. 8B, the coupling of the control line retainer arm 30 with
the docking assembly 150 urges docking member 55 to reposition link 124 to rotate
blocking member 120 to the retracted position shown in Fig. 8B and to thereby permit
pivotal closure of the halves 102 of the CLS landing spear 100 to surround the pipe
string (not shown). The docking of the control line retainer arm 30 adjacent to the
CLS landing spear 100 removes the control lines 90 from the operating zone of the
CLS landing spear 100. It should be understood that the embodiment of the docking
member and blocking member disclosed in connection with Figs. 8A and 8B does not include
any non-mechanical devices, such as cylinders, to implement the safety interlock system.
[0089] Fig. 9A is a perspective view of one embodiment of an automatic safety latch 61 to
allow the control line retainer arm (not shown) to be raised by the drive member (not
shown) to a raised position, but to prevent inadvertent lowering of the control line
retainer arm until the safety latch 61 is disabled by rig personnel. Fig. 9A is a
perspective view of one embodiment of a retainer arm safety latch 61 to selectively
permit raising of the control line retainer arm to the raised position (see retainer
arm 30 in Fig. 4), but to block the control line retainer arm from being returned
to the removed position until an operator overrides the safety latch 61. The safety
latch of Fig. 9A comprises a pivotal track blocker 68 with a pivot 68A and a spring-biased
cylinder 67. The cylinder 67 may be spring biased to pivot the track blocker 68 against
the stop 65 and into the safety position shown in Fig. 9A. The cylinder 67 may be
energized by a supply of pressurized fluid through conduit 67E to extend the cylinder
67 and override the springs 67D and auxiliary spring 66 and to pivot the track blocker
68 out of the safety position. The cylinder 67 may also be extended by movement of
the follower 39 through the portion of the track 69 adjacent to the track blocker
68 in the direction of the arrow 64A and toward the upper end 69B of the track 69.
[0090] Fig. 9B is the perspective view of Fig. 9A after the follower 39 on the retainer
arm has moved through a portion of the track 69 adjacent to the safety latch 61 to
enter the portion 69B of the track 69 corresponding to the raised position of the
retainer arm. The track blocker 68 pivots out of the blocking position shown in Fig.
9A due to the camming action of the follower 39 along the ramped surface 69C of the
track blocker 68 as it is driven along the path of the track 69 in the direction of
arrow 64A (See Fig. 9A). It should be understood that in the event that the retainer
arm and the follower 39 are driven along the track 69 in the reverse direction and
against the blocking surface 68B of the track blocker 68, the track blocker 68 will
be pivotally urged against the stop 65, and that the control line retainer arm 30
(not shown in Fig. 9B) will be blocked from being returned to the removed position
with the follower 39 nearer the lower end of the track 69 unless the track blocker
68 is pivoted out of the safety position. The track blocker is shown in the safety
position in Figs. 9A and 9B.
[0091] Fig. 9C is the perspective view of Fig. 9B with the safety latch disabled to permit
lowering of the retainer arm back toward the removed position. The safety latch shown
in Figs. 9A-9C is one example of a fail-safe safety latch. Fig. 9C shows the safety
latch 61 disabled by a supply of pressurized fluid to cylinder 67 to override the
spring bias and to permit passage of the follower 39 in the direction of arrow 64B
and the corresponding lowering of the control line retainer arm back toward the removed
position. The safety latch 61 may be disabled, for example, by a rig personnel depressing
a button (not shown) to open a valve (not shown) feeding pressurized fluid through
fluid conduit 67E and to the cylinder 67 to override the bias of the springs 66 and
67D to pivot the track blocker 68 out of the safety position (as shown in Fig. 9C),
and by clearing the track 69 to permit the follower 39 to move along the track 69
in the direction of arrow 64B.
[0092] Fig. 10 is a perspective view of an alternative control line retainer 50 coupled
to the second end 30B of the control line retainer arm 30 of a control line positioning
apparatus. The alternative retainer assembly 50 comprises a generally hollow sleeve
49 to surround and position the control line 90. The interior of the sleeve 49 may
comprise a material having favorable lubricity for sliding engagement with the control
line, and may be lubricated, to produce favorable low-friction sliding of the control
line 90. It should be understood that, although the alternative retainer assembly
50 of Fig. 10 is shown engaging a docking assembly to secure the retainer arm in the
removed position, the alternative retainer assembly may be used without a docking
assembly.
[0093] Fig. 11 is a perspective view of an alternate embodiment of a control line positioning
apparatus 210 comprising a rotatable and translatable control line retainer arm 130
positionable by a drive member 113 between a removed position shown in Fig. 11 and
a raised position shown in Fig. 12. The embodiment of the control line retainer arm
130 of Fig. 11 is coupled to a docking assembly 150 that cooperates with a CLS landing
spear 100 when the control line retainer arm 130 is in the removed position shown
in Fig 11 to restrain the control line 90 from entering the operating zone of the
CLS landing spear 100. The alternate embodiment of the control line positioning apparatus
210 of Fig. 11 also comprises an ascending control line feed pathway 112 having an
inlet 116 proximate the base 12 to receive a control line feed and an outlet 118 generally
above or proximate to the control line retainer arm 130 to direct the control line
feed to a control line retainer assembly 115 coupled to the second end 130B of the
retainer arm.
[0094] Fig. 12 is the perspective view of the control line positioning apparatus 210 of
Fig. 11 after the halves 102 of the CLS landing spear 100 are unloaded and pivoted
to the open position, and after the control line retainer arm 130 is moved by the
drive member 113 from the removed position shown in Fig. 11 to the raised position
shown in Fig. 12. The drive member 113 is shown in an extended condition after it
has moved the follower 139 on the control line retainer arm 130 along the path of
the track 169.
[0095] Fig. 13 is a perspective view of control line storage reels stored in a rig sub-space
beneath a rig floor supporting a control line positioning apparatus (not shown in
Fig. 13). The sub-space may be used to store and supply control line 90 to a control
line positioning apparatus through an aperture 116A in the rig floor that may, in
one embodiment, be aligned with the inlet 116 to an ascending pathway 112 on a control
line positioning apparatus (see, for example, the control line positioning apparatus
210 in Figs. 11 and 12). A sheave 176 may be used to redirect the control line feed
from the reel 174 into the aperture 116A.
[0096] Fig. 14 is an elevation cross-section view of an alternate embodiment of a control
line positioning apparatus 210 revealing the path of the ascending control line feed
pathway 112 comprising rolling members (not shown, but positions indicated by rolling
member axles 119) supported by one or more frames 111 connected to the track 169 that
engages and guides the follower 139 of the control line retainer arm 130. Rolling
member axles 119 may support rolling members that are strategically positioned to
define the ascending control line feed pathway 112 and to prevent bending any portion
of the control line feed beyond the minimum bend radius. In one embodiment, the control
line feed pathway may be adjustable. The inlet 116B of the embodiment of the ascending
control line feed pathway 112 of Fig. 14 is aligned with the outlet of a rig floor-mounted
control line feed pathway, as will be described below in connection with Figs. 15
and 16.
[0097] It should be understood that the ascending control line pathway 112 may be adapted
to receive a control line feed through an aperture 116 in the rig floor, as shown
in Figs. 11 and 12, from an outlet 218 of a rig floor-mounted control line pathway
220, as shown in Fig. 14, or from a control line feed in other locations.
[0098] Fig. 15 is a perspective view of one embodiment of a rig floor-mounted control line
pathway 220 having an inlet 216 to receive a control line feed, an outlet 218 to discharge
the control line feed to an inlet 116B to an ascending control line feed pathway of
a control line positioning apparatus (not shown in Fig. 15), and a bend portion 250
intermediate two generally straight control line channels 220. The embodiment of the
rig floor-mounted pathway of Fig. 15 provides a protected channel through which one
or more control line feeds may be delivered to a control line positioning apparatus.
The rig floor-mounted pathway 220 of Fig. 15 may comprise an elongate cover support
230 in a spaced-apart relationship from an adjacent cover support 230 to define a
channel therebetween. In one embodiment, the cover supports 230 may each comprise
a triangular cross-section to provide a ramp over which personnel and equipment may
pass. A channel cover 234 may be hingedly coupled to one of the cover supports 230
and pivotable between a closed position to protect the control line feed channel there
beneath, as in Fig. 15, and an open position to provide access to the control line
feed channel, as shown in Fig. 16. Windows 232 in the channel cover 234 may provide
rig personnel with visual access to at least a portion of the control line feed channel
with the covers 234 in the closed position.
[0099] Fig. 16 is the perspective view of Fig. 15 after hinged channel cover 234 on the
straight portions of the rig floor-mounted pathway are pivoted to an open position
to provide access to the control line feed channel and to the control lines 90 therein.
A cover on the bend portion 250 is also removed to reveal an array of rolling members
256a-256c for maintaining a spaced-apart relationship between the control lines 90
as the control lines are redirected in the bend portion into a subsequent channel
portion.
[0100] It should be noted that the rig floor-mounted control line pathway may be secured
to the rig floor 8 using fasteners that, when the cover supports 230 are slid and
secured in place, are hidden from view and access in order to prevent tripping or
snagging hazards, as illustrated on the straight portions of the pathway 220 in Figs.
15 and 16. Alternately, portions of the rig floor-mounted control line pathway may
be secured to the rig floor using visible, external fasteners 252, as shown for the
bend portion 250 of the pathway in Figs. 15 and 16.
[0101] Fig. 17 is a top plan view of the array of rolling members 256a-256c within the bend
portion 250 of the floor-mounted control line pathway 220 of Figs. 15 and 16 showing
one possible arrangement of an array of rollers within the bend portion 250, and also
showing one embodiment of a load cell 262 coupled to the rig floor 8 and to the bend
portion 250 to facilitate measurement of the tension of the control lines 90. The
bend portion 250 may be movably secured to the rig floor using fasteners 257 slidably
received within slots 259 to permit limited movement of the bend portion, as restrained
by a spring 261 biasing the bend portion 250 in a direction opposite to the movement
urged by tension in the control lines 90 that traverse the array of rolling members
256a-256c. It should be understood that a spring scale, fluid cylinder, strain gauge,
or other load measuring device may be used to measure the force imparted to the bend
portion 250 as a result of the tension in the control lines 90. It should further
be understood that these devices may be used, along with commonly used instruments
and devices, to generate a signal 260 corresponding to the measured force imparted
by the bend portion 250, and to initiate an alert, display, or automatic emergency
shut-down of the control line feed operation as necessary to maintain and protect
the control line feed operation, the control line and the related equipment.
[0102] Fig. 18A is an elevation view of one embodiment of a rectilinear control line positioning
apparatus 300 comprising a control line retainer assembly 50 positionable, in part,
by a horizontal cross-slide 309 that is vertically positionable on vertical brace
301 by a vertical lift cylinder 302. The lift cylinder 302 on the brace 301 may retract
to lift and extend to lower the horizontal cross-slide 309. The horizontal cross-slide
309 may be positioned vertically by extending and retracting cylinder 302 by controlling
a feed of pressurized fluid to the cylinder through conduits (not shown). The horizontal
cross-slide 309 is comprises a vertically reciprocating base 311 that is slidably
coupled to the brace 301 by the vertical cylinder 302 and by a "T"-shaped rail 310
received into a corresponding "T"-shaped groove (not shown) in reciprocating base
311. The horizontal slide member 309 is horizontally extendable by operation of cylinder
312 to extend and retract the control line retainer assembly 50.
[0103] Fig. 18A shows the control line positioning apparatus 300 with the control line retainer
assembly 50 in the removed position to restrain the control lines 90 from entering
the operating zone of the spider 70.
[0104] Fig. 18B shows the control line positioning apparatus of Fig. 18A after the vertical
lift cylinder 302 is retracted to lift horizontal cross-slide 309 and the extension
cylinder 312 is used to extend the control line retainer assembly 50 to a raised position
proximate the pipe string 80 and to position the control line 90 along a portion of
the pipe string 80 above the spider 70 to facilitate clamping of the control line
90 to the pipe string 80.
[0105] FIG. 19 is a side view of the frame 62 supporting one or more rolling members 114
rotatable about rolling member axles 119, thereby defining at least a portion of the
ascending pathway 112. A load transfer member, or subassembly 180, may include one
or more members 256, such as rolling members, in which the rolling members may be
rotatable about rolling member axles 188. The subassembly 180 may be used to position
the rolling members 256 to cooperate with the rollers 114 to define at least a portion
the ascending pathway 112. Further, the subassembly 180 may be movably secured to
the frame 62 to permit limited movement of the subassembly 180 in a direction of a
mounting bracket 192. A biasing member, such as a spring (not shown), may be used
to bias the subassembly 180, such as bias the subassembly 180 in a direction opposite
to the movement urged by tension in the control line 90 traversing the plurality of
rolling members 256. A scale, strain gauge, load cell, and/or any other load measuring
device 194 may be used to measure the force imparted to the subassembly 180 as a result
of the tension in the control lines 90. It should be understood that the load measuring
device 194 may be used, along with commonly used instruments and devices, to generate
a signal corresponding to the measured force imparted on the subassembly 180. For
example, the load measuring device 194 may include and/or have coupled thereto one
or more guides and/or a sensor, in which the sensor may be able to measure a force
imparted thereto, such as the shear force imparted thereto. The sensor may then be
able to measure a load applied to the subassembly 180 though the control line 90.
In one embodiment, the sensor may be disposed within the mounting bracket 192, in
which a bearing, such as a spherical bearing, may be disposed within the mounting
bracket 192 with the sensor. In such an embodiment, the bearing may be used to prevent
twisting and/or any other movement and/or warping of the guides, sensor, and/or the
subassembly 180. As such, this may increase the accuracy of the measurements for the
load measuring device 194. Further, the load measuring device, or an instrument coupled
thereto, such as a controller, may be used to initiate an alert, display, or automatic
emergency shut-down of the control line feed operation as necessary to maintain and
protect the control line feed operation, the control line and the related equipment.
[0106] Another embodiment of the apparatus and the method of the present disclosure may
provide safeguards against tensile or other failure or rupture of the control line,
such as when the control line is being connected to the pipe string and as the pipe
string is made-up and run into the borehole. Figs. 20 and 21 show an embodiment of
a deployable control line cutter 201 in accordance with the present disclosure that
may be actuated to engage and cut or sever a control line 90 at a controlled location
along the control line. As such, the control line cutter 201 may be used to prevent
parting of the control line at a location that may be difficult, if not impossible,
to retrieve, repair, and/or otherwise remediate the control line failure without great
expense and rig downtime. For example, it may be desirable to prevent the control
line from severing within the borehole because this may require removal of at least
a portion of pipe string from the borehole to reconnect and repair the control line.
[0107] Fig. 20 is a perspective view of an embodiment of a control line cutter in the retracted
or ready position in accordance with the present disclosure. The embodiment of the
control line cutter 201 may include a cutting member 203 that may be pivotable between
a retracted position, such as shown in Fig. 20, and a deployed position, such as shown
in Fig. 21. In one or more embodiment, the control line cutter 201 may be used to
engage and/or guide the control line 90 without having the cutting member 203 engage
the control line 90. For example, the control line cutter 201 may rotate when engaged
with the control line 90, such as shown in Fig. 20, but the cutting member 203 may
independently rotate with respect to the control line cutter 201 such that the cutting
member 203 does not rotate and engage the control line 90. In one embodiment, the
control line cutter 201 may be biased towards the deployed position, such as to engage
and cut the control line 90 at a location adjacent to the pivotable cutting member
203. The control line cutter 201 may be biased to pivot from the retracted position
to the deployed position using, for example, a biasing member, such as a coil spring
207, a torsion spring, or any other biasing member known in the art. The coil spring
207 may be coupled intermediate the control line cutter 201 and a cutter support that
may be supported, such as rotationally supported, from the frame 62. The control line
cutter 201 may be secured in the retracted position, in opposition to the biasing
coil spring 207, such as by one or more retainers 204 that may be coupled to an actuator.
For example, the retainers 204 may be secured to a rod of a cylinder 202. The cylinder
202 may be hydraulically operated and coupled to a hydraulic fluid line (not shown)
that selectively depressurizes the cylinder 202 to deploy the control line cutter
201 in response to an emergency condition, such as may be detected by excessive tension
in the control line 90. Further, an optional cutter sensor 209 may be used to generate
a signal in response to sensing deployment of the cutting member, such as a pressure
sensor in communication with the fluid in or to the cylinders 202.
[0108] The system preferably includes first and second retainers operated by first and second
actuators. In such an embodiment, both retainers may be required to disengage from
the cutting member before the cutting member is allowed to rotate to cut the control
line. The use of redundant actuators and respective retainers may decrease the likelihood
that the cutting member is accidentally deployed.
[0109] In one embodiment, the control line cutter system may include a back-up member 210.
The back-up member 210 may be disposed adjacent the control line cutter 201 with the
pathway 112 of the control line 90 disposed intermediate the pivotable control line
cutter 201 and the back-up member 210. The back-up member 210 may be stationary or
movable. For example, in one embodiment, the back-up member 210 may be pivotable about
an axle 213 such that the back-up member 210 may rotate with the control line under
normal feeding and/or as the control line cutter 201 pivots to engage and cut the
control line. Specifically, depressurizing the cylinders 202 may allow the retainers
204 to disengage from the control line cutter 201 such that the spring 207 causes
the control line cutter 201 to rotate counterclockwise (as seen in Fig. 20). After
slight rotation, the pivotable cutting member 203 may then engage and cut the control
line 90.
[0110] It should be understood that the control line cutter 201 may be used to prevent parting
of the control line due to excessive loading of the control line. A control line cutter
may be included with and/or within a control line pathway, a spider (e. g., a control
line pathway extending through the bore of the spider), a CLS pipe engaging apparatus,
and/or a control line manipulator (e. g., as shown in Fig. 20). Excessive loading
may be caused, for example, by lowering of the pipe string, to which the control line
is coupled, into the borehole with some impediment or excessive resistance to continuous
feeding of the control line to the borehole through the ascending pathway.
[0111] In one embodiment, an actuator, e. g., electrically or fluidically powered (hydraulic
or pneumatic) motor, 206 may be provided in communication with (e. g., fluidic or
electrical communication) a source of energy (e. g., controlling lines 205A and 205B)
to cause rotation of and/or drive a drive member, such as a drive roller 208 or a
conveyor belt, in which the drive roller 208 may engage the control line 90. A drive
member may include an outer surface including a resilient material, such as an elastomeric
material. Further, in one or more embodiments, a motor may be used to drive a drive
member using, for example, a keyed shaft coupled between the motor 206 and the roller
208, in which torque and/or rotation may be transmitted from the motor 206 to the
drive roller 208. Alternatively, a spur gear, a splined shaft, and/or any other mechanism
known in the art, such as a one-way rotational mechanism, may be used to enable the
motor to drive the drive roller. A back-up member may also be used, such as with the
drive member. For example, the back-up member may include an adjustable rolling member
212, which may be disposed adjacent to the drive roller 208 with the control line
90 passing therebetween. Additionally or alternatively, the back-up member may include
a conveyor belt, a support member (e. g., a plate or a non-rotatable support), a low
friction control line contacting surface, and/or any other member or device known
in the art that may be used with the drive member, such as to support a control line.
Further, a passive rolling member, such as a passive roller, may be used within a
control line system in accordance with the present disclosure. The passive rolling
member may include a one-way rotational mechanism, in which the one-way rotational
mechanism may enable the passive rolling member to selectively rotate in one direction
or in two directions. As such, when a one-way rotational mechanism is engaged, the
passive rolling member may only rotate in one direction, as compared to when the one-way
rotational mechanism is not engaged, in which the passive rolling member may rotate
in two directions.
[0112] Further, (for example through, one or more adjustment handles 211) the rolling member
212, such as each end of the rolling member 212, may extend toward or retract away
from the control line 90, e. g., via an actuator coupled thereto and/or any other
means known in the art. The rolling member 212 and the drive roller 208 may be used
to create friction against the control line 90 passing therebetween with the drive
roller 208 such that the drive roller 208 may be able to drive, feed, and/or otherwise
control force and/or movement of the control line 90 being engaged by the drive roller
208. Adjusting the position of the rolling member 212 may press the control line 90
against the drive roller 208 such that the motor 206 can push, pull, and/or otherwise
provide a force to the control line 90. A drive member may be controlled to feed,
e. g., move axially, a control line at a desired rate, such as a rate equal to the
rate that the pipe string is advanced into the borehole, or to maintain a desired
amount of tension in the control line.
[0113] In one or more embodiments, the drive member, e. g., roller 208, in addition to other
components and/or equipment, may be used to provide a force to a control line 90,
such as to pull the control line 90 through a control line pathway of a control line
positioning apparatus. For example, by pulling, or feeding, the control line 90 with
the driver roller 208, the control line 90 may have sufficient enough slack developed
therein such that the control line 90 may be manipulated as desired, such as handled
by one or more persons or by control line handling equipment, such as to clamp the
control line to a pipe string. In such an embodiment, after the drive roller 208 has
driven the control line 90, at least partially, within and/or through the control
line pathway, the control line 90 may be cut, such as using the control line cutter
201, in which the drive roller 208 may maintain engagement with the control line 90.
[0114] In one or more embodiments, the drive member, e. g., drive roller 208, may rotate
and/or be driven in one direction and/or in two directions. For example, the drive
member may be used to drive and feed the control line 90 into a borehole and/or out
from a borehole. However, in such embodiments, the drive member may be prevented from
rotating in both directions, such as after the control line cutter 201 has been activated
to cut the control line 90. In such an embodiment, the drive member may be used to
feed the control line 90 in a direction further downhole into a borehole, but may
be prevented from rotating such that the control line 90 may not recoil back and have
the drive member lose engagement with the control line 90. As such, in one embodiment,
a check valve, such as a pneumatic pilot valve, and/or any other appropriate sensor
or mechanism may be activated when desired to have the drive member drive a control
line in one direction and/or in two directions. For example, the check valve may be
opened and closed in response to the movement of the control line cutter 201. The
check valve may then prevent the movement of the motor 206 and/or the drive member,
at least movement in one direction, after the control line 90 has been cut. In such
an example, the drive member may be able to maintain engagement with the control line
90 to prevent movement of the control line 90, such as by preventing the control line
90 recoil and be released from engagement with the drive member.
[0115] Furthermore, in one or more embodiments, the motor 206 and/or the drive member, e.
g., drive roller 208, may be used when handling and/or otherwise managing one or more
of the control lines 90 in use with a drilling rig. For example, when handling a control
line, such as when lifting and/or pulling a control line, a tether (e. g., a rope
or cable) may be connected and attached to the control line. The tether may be driven,
at least partially, by the motor 206, e. g., a moving portion of the motor 206, and/or
the drive member, such as by having the tether disposed about the motor 206 and/or
the drive member. Accordingly, the motor 206 and/or the drive member may be used as
a winch, such as a capstan winch, in which the motor 206 and/or the drive member may
be used to assist in handling the control line. For example, the tether may be disposed
about and fed around the motor 206, in which the motor 206 may be rotated and driven
to operate as a winch, thereby enabling the motor 206 to lift, pull, and/or otherwise
handle the control line as desired. Those having ordinary skill in the art will also
appreciate that the present disclosure contemplates multiple other methods and uses
in accordance with one or more embodiments disclosed herein.
[0116] Fig. 21 is a perspective view of the control line cutter 201 in accordance with the
present disclosure. In Fig. 21, the cylinder 202 may be depressurized and the retainers
204 may be released from the control line cutter 201 to enable the control line cutter
201 to pivot under the bias of the spring 207. The pivotable cutting member 203 may
include a contacting surface, such as teeth 203B, that initially engage the side or
outer casing of the control line 90. As the control line 90 continues to advance along
the pathway, the control line 90 pulls on the teeth 203B to cause and/or assist further
pivoting of the cutting member 203 until the cutting blade 203A slices into and through
the control line 90. The portion of the control line 90 that is downstream from the
cut may then be free to advance and relieve tension in the control line 90 such that
the control line does not become damaged in an undesirable location and/or cause damage
to other equipment. The portion of the control line 90 that is upstream and/or proximal
of the cutting blade 203A may be secured between the drive roller 208 and the adjustable
roller 212. Optionally, a complete loss of tension in the control line 90 may be detected
and cause the hydraulic motor 206 to lock the drive roller 208 against rotation. When
a control line 90 has been cut, as described, the control line cutter 201 may be reset
before reconnecting the control line 90 and running the control line 90 into the borehole
along with the pipe string. Those having ordinary skill in the art will appreciate
that the system of Figs. 20 and 21 may be operated in many different ways to prevent
harm to personnel and equipment, as well as to safeguard the control line that has
already been run into the borehole. In one embodiment, the actuator may release the
retainer upon loss of fluid pressure to the actuator. For example, the actuator may
release the retainer upon receiving a signal generated by a control line tension sensor.
In accordance with Figs. 15-17 and 19, a control line tension sensor may detect whether
a force imparted by the control line to a load transfer member exceeds a predetermined
setpoint force. The signal received by the actuator may be in the form of an electronic
signal or a fluid pressure signal.
[0117] In one embodiment, the system may include a controller that controls operation of
the actuators 202, in addition to multiple other components of the system. The controller
may be designed or programmed to control the actuator based upon one or more signals
received from one or more sensors. For example, one or more sensors may be selected
from a control line tension sensor, a dropped pipe string sensor, and an emergency
shut-down sensor. A suitable control line tension sensor may be disposed to measure
forces in a bend of a control line pathway, such a rig floor mounted pathway or an
ascending pathway of a control line positioning apparatus. In a further embodiment,
the controller operates the actuator to allow rotation of the cutting member in response
to receiving a signal from the control line tension sensor that indicates the tension
is greater than a setpoint tension. Optionally, the setpoint tension may be selected
to prevent an excessive load on the control line that could cause unwanted parting
of control line and whipping. Additionally or alternatively, a system may include
a control line speed, velocity, acceleration, rotation, etc. sensor, such as a sensor
to provide a speed signal to the controller. In one embodiment, a sensor may be coupled
to one or more rollers (e. g., passive roller), one or more drive members, and/or
any other component(s) of a control line system, e. g., a component that engages and/or
moves with the control line, in which the sensor may be able to detect and measure
one or more parameters, as desired. For example, a controller may compare the speed
of the control line to the maximum desired descent speed (e. g., indicating a drop
string) of the pipe string and operates the actuator to cut the control line in response
to the control line speed exceeding the maximum descent speed of the pipe string.
Other variations and combinations of control schemes for controlling the cutting member,
and/or any other member or component within a control line system, are considered
to be within the scope of the present disclosure.
[0118] Fig. 22 is a perspective exploded view of an alternate embodiment of a control line
cutter 201 in accordance with the present disclosure. The control line cutter 201
may be primed using an accessible sprag clutch 215 and a cooperating spring 207A that
may be used to prevent the need for inserting a hand into the interior of a control
line manipulating machine or other enclosure. Fig. 22 illustrates a pivotable cutting
member 203 that may include a cutting blade 203A and/or a contacting surface thereon.
For example, the contacting surface may include teeth 203B, as shown, may include
a control line engaging surface to frictionally engage a control line, and/or may
include any other surface, material, or device that may be used to engage and contact
a surface of a control line. The pivotable cutting member 203 of Fig. 22 further may
include an axle 203C having a slot 203D therein to receive an interior anchor leg
207B of spring 207A upon assembly of the control line cutter 201. Further, one or
more spacers 225 and 227 may be provided for ease of assembly and to ensure alignment
and proper engagement of the components of the control line cutter 201.
[0119] A clutch, such as a sprag clutch 215, may include a unidirectional member, such as
a ratcheting member, that permits rotation of the (as shown in Fig. 22) sprag clutch
in a first (e. g., clockwise) direction to "prime" (e. g., to store energy with) the
spring 207A component of the control line cutter 201. The exterior anchor leg 207C
of the spring 207A, which may be received in a gap 215A of the sprag clutch 215, may
thus be pivoted relative to the interior anchor leg 207B of the spring 207A. Further,
the spring 207B may be received in the slot 203D of the axle 203C to store energy
in the spring 207A and to bias the pivotable cutting member 203 from the retracted
position illustrated in Fig. 23 and towards the engaged position with the control
line (not shown in Fig. 22 - see, e. g., Fig. 21). The control line cutter may be
secured in the assembled condition using a cotter pin 215B disposed within a groove
(not shown) on the axle 203C and within the sprag clutch 215.
[0120] Fig. 23 is an elevation view of a portion of a control line manipulator (e. g., the
control line manipulator illustrated in Fig. 14) equipped with the alternative embodiment
of the control line cutter 201 of Fig. 22 in accordance with the present disclosure.
The cylinder 202 and the retainer 204 may be supported by the control line manipulator
immediately adjacent to and in engagement with the pivotable cutting member 203 of
the control line cutter 201. The cylinder 202 may be pressurized to extend the retainer
204 to engage and retain the pivotable cutting member 203 in the retracted configuration.
Further, the sprag clutch 215 may be accessible from outside the control line manipulator
for manual rotation to prime the spring (not shown in Fig. 23 - see Fig. 22). The
cylinder 202 may be spring-biased to retract and withdraw the retainer 204 from engagement
with the pivotable cutting member 203 upon depressurizing of the cylinder 202. Once
disengaged by the retainer 204, the pivotable cutting member 203 may pivot about an
axle (not shown in Fig. 23 - see element 203C in Fig. 22) as biased by the spring
207A in the counterclockwise direction (as seen in Fig. 23) to engage and cut the
control line 90.
[0121] Fig. 24 illustrates an alternative embodiment of a control line cutting member in
accordance with the present disclosure. The control line cutting member may employ
a non-pivoting cutting member that is self-energized upon engagement with a moving
control line. As shown in Fig. 24, a cutting member 240 may be movably coupled to
a cutting member pathway 241, and adjacent to a control line 90. Further, the cutting
member 240 may be retained in the retracted position by a retainer 204 coupled to
a spring-biased cylinder 202. The retainer 204 may obstruct the movement of the cutting
member 240 along the cutting member pathway 241, such as until the retainer 204 may
be withdrawn from the position illustrated in Fig. 24 by depressurization of the cylinder
202, which results in the cutting member 240 moving downwardly (in Fig. 24) along
at least a portion of the cutting member pathway 241 to engage and cut the control
line 90 that is moving in the direction of the arrow 90A. As can be seen from Fig.
24, the cutting member 240 and the cutting member pathway 241 may be arranged, relative
to the pathway and direction of movement of the control line 90, to facilitate engagement
of the cutting member 240 with the control line 90 in a self-energizing mode. That
is, the tension in the control line 90 may draw the cutting member 240 further along
the cutting member pathway 241 to cause the cutting member 240 to be forced further
into cutting engagement with the control line 90.
[0122] Fig. 24A is a section view of one embodiment of the cutting member pathway 241 in
accordance with the present disclosure. The cutting member pathway 241 may be used
to facilitate movement of the cutting member 240 upon retraction of the retainer 204.
In one embodiment, the force used to move the cutting member 240 upon release from
the retracted position illustrated in Fig. 24 to the engaged position (not shown)
with the control line 90 may be, for example, gravity, a spring or other biasing member,
or a combination of both.
[0123] Fig. 25 is an alternate embodiment of the control line cutting member of Fig. 24
in accordance with the present disclosure. As shown, this embodiment may include two
cutting members 240 movably coupled to two opposed cutting member pathways 241 and
restrained in the retracted positions using retainers 204 coupled to pressurized cylinders
202.
[0124] It should be understood that, in the above embodiments, such as with respect to Figs.
19-25, a control line positioning apparatus is shown to be included and in use with
a movable cutting apparatus, in which the cutting apparatus may be used to cut a control
line. Further, a control line positioning apparatus is shown to be included and in
use with a load transfer member, a load measuring device, and a drive member, in which
each of these pieces of equipment may be used with a control line. However, those
having ordinary skill in the art will appreciate that the present disclosure is not
so limited, as a cutting apparatus, a load transfer member, a load measuring device,
and/or a drive member in accordance with the present disclosure may be used, e. g.,
separately or in combination, with any equipment and/or method for running a control
line. For example, in one embodiment, a pipe engaging apparatus, such as a spider
or a CLS pipe engaging apparatus, which may be used to engage and/or support one or
more tubular members, may incorporate the use of a cutting apparatus in accordance
with the present disclosure. The cutting apparatus may be disposed within the pipe
engaging apparatus such that the cutting apparatus may engage and cut a control line
that passes through and/or adjacent to the pipe engaging apparatus. In another embodiment,
a pipe engaging apparatus may additionally or alternatively may incorporate the use
of a load transfer member, a load measuring device, and/or a drive member in accordance
with the present disclosure. Accordingly, the present disclosure contemplates multiple
other embodiments and is not limited only to the embodiments shown and discussed above,
as one or more of the apparatuses and methods disclosed herein may be used with running
a control line and/or handling a control line, such as running a control line on a
rig.
[0125] In yet another embodiment of a method of cutting a control line, other preventive
or remedial steps may be taken. For example, the control line tension sensor may generate
a signal that may be communicated to a pipe string elevator to slow the descent of
the pipe string. Furthermore, the control line tension sensor may generate a signal
that is communicated to a control line feed drive motor, optionally increasing the
speed of the drive motor in response to a signal indicating high tension in the control
line.
[0126] In accordance with the present disclosure, a control line inhibiting apparatus may
be included within one or more embodiments disclosed herein such that the control
line inhibiting device may be able to inhibit and prevent a control line from being
further fed into a control line positioning apparatus, a pipe engaging apparatus,
and/or any other apparatus or device used to receive a control line. For example,
the control line inhibiting apparatus may include a brake and/or a shear mechanism
configured to engage the control line such that the control line inhibiting apparatus
inhibits and prevents movement of the control line (e. g., feeding of the control
line), or such that the control line inhibiting apparatus at least reduces the rate
of movement of the control line (e. g., reduces the feeding rate of the control line).
Those having ordinary skill in the art will also appreciate that other control line
inhibiting apparatuses may be used in accordance with one or more embodiments disclosed
herein.
[0127] It should be understood that an "elevator assembly," as used herein, means a vertically
movable spider, a casing running tool (CRT) or any other pipe gripping assembly that
can be manipulated to raise or lower a pipe string that is supported within the elevator
assembly. It should be further understood that "pipe gripping apparatus," as used
herein, means an apparatus that can support a pipe string, and specifically includes
an elevator assembly and also includes a spider.
[0128] In one aspect, embodiments disclosed herein generally relate to an apparatus, method,
and/or system that may be used to attach a control line to a tubular member. The apparatus
includes a control line arm having a first control line guide coupled thereto, a base
having a second control line guide coupled thereto, with the control line arm coupled
to the base and movable with respect to the base. The control line arm is movable
between a raised position and a collapsed position with respect to the base, such
as by having the control line arm slidably coupled and/or rotatably coupled to the
base.
[0129] The control line arm may include a first end and a second end, in which the first
control line guide may be disposed adjacent the first end of the control line arm
with the second end of the control line arm movably coupled to the base. As such,
the control line arm and/or the base may include a sliding element, such as a track,
to slidably couple the control line arm to the base. Further, the control line arm
may include a first control line arm and a second control line arm. The first control
line arm and the second control line arm may be coupled to the base and movable with
respect to the base, in which the first control line guide may be disposed between
the first control line arm and the second control line arm. Furthermore, the first
control line guide and/or the second control line guide may include one or more rollers.
[0130] The apparatus may include one or more support members to help support, guide, and
facilitate movement of the control line arm, the first control line guide, and/or
the second control line guide. For example, a first support member may be rotatably
coupled to the control line arm and rotatably coupled to the base to provide support
thereto. Further, a second support member and a third support member may be included,
in which the second support member may be rotatably coupled to the base and to the
third support member, with the third support member coupled to the control line arm
adjacent the first control line guide.
[0131] Referring now to Figs. 26A-26C, multiple perspective views of an apparatus 2600 to
attach a control line 2602 to a tubular member 2604 in accordance with one or more
embodiments of the present disclosure are shown. Specifically, Fig. 26A provides a
side perspective view of the apparatus 2600, Fig. 26B provides an above front perspective
view of the apparatus 2600, and Fig. 26C provides an above back perspective view of
the apparatus 2600.
[0132] The apparatus 2600 includes a base 2610 and one or more control line arms 2620. As
shown in Figs. 26A-26C, the apparatus 2600 includes two control line arms 2620A and
2620B, but those having ordinary skill in the art will appreciate that one or more
embodiments in accordance with the present disclosure may include only one control
line arm, or may include more than two control line arms, each without departing from
the scope of the present disclosure. Accordingly, the first control line arm 2620A
and/or the second control line arm 2620B may be coupled to the base 2610 such that
the first control line arm 2620A and the second control line arm 2620B are movable
with respect to the base 2610. For example, the first control line arm 2620A and the
second control line arm 2620B may movable between a raised position (as shown in Figs.
26A-26C) and a collapsed position with respect to the base 2610.
[0133] In one or more embodiments, the first control line arm 2620A and the second control
line arm 2620B may be slidably coupled and/or rotatably coupled to the base 2610.
As such, the first control line arm 2620A, the second control line arm 2620B, and/or
the base 2610 may include a sliding element to slidably couple the first control line
arm 2620A and the second control line arm 2620B to the base 2610. One having ordinary
skill in the art will appreciate that any sliding element known in the art may be
used to facilitate slidably coupling a control line arm to a base, such as a track,
a rail, a pathway, a roller, wheel or similar rolling element, a low-friction sliding
element, and/or any other sliding element known in the art. For example, as shown
in Figs. 26A-26C, the base 2610 may include one or more tracks 2612 formed therein
and/or attached thereto. As such, an end of the first control line arm 2620A may be
received within a first track 2612A such that the end of the first control line arm
2620A may be rotatably coupled and/or slidably coupled to the first track 2612A. Similarly,
an end of the second control line arm 2620B may be received within a second track
2612B such that the end of the second control line arm 2620B may be rotatably coupled
and/or slidably coupled to the second track 2612B. By having this engagement between
the first control line arm 2620A and/or the second control line arm 2620B with the
base, the apparatus 2600 may be movable between a raised position and a collapsed
position.
[0134] The apparatus 2600 may include one or more control line guides included therein and/or
coupled thereto. As shown in Figs. 26A-26C, the first control line arm 2620A and/or
the second control line arm 2620B may have a first control line guide 2640A coupled
thereto, and the base 2610 may have a second control line guide 2640B coupled thereto.
A control line guide in accordance with the present disclosure may be any device or
apparatus configured to guide a control line. Accordingly, a control line guide in
accordance with the present disclosure may include one or more rollers, sheaves, or
any other device known in the art to guide a control line. As shown in Figs. 26A-26C,
the first control line guide 2640A may include a plurality of rollers 2642, and similarly
the second control line guide 2640B may a plurality of rollers 2642.
[0135] The first control line arm 2620A and the second control line arm 2620B may have one
end coupled to the base 2610 of the apparatus 2600. As such, another end of the first
control line arm 2620A and the second control line arm 2620B may have the first control
line guide 2640A coupled thereto and/or disposed adjacent thereto. For example, as
shown in Figs. 26B and 26C in particular, in an embodiment having two control line
arms, the first control line arm 2620A and the second control line arm 2620B, the
first control line guide 2640A may be disposed between and coupled to the first control
line arm 2620A and the second control line arm 2620B using a link 2646. The link 2646
may be connected to the ends of the first control line arm 2620A and the second control
line arm 2620B, with the first control line guide 2640A then connected to the link
2646. In an embodiment in which the first control line guide 2640A includes the rollers
2642, the control line 2602 may be reeved over the rollers 2642 of the first control
line guide 2640A and under the link 2646.
[0136] Further, the second control line guide 2640B may be coupled to the base 2610. As
such, and as shown in Figs. 26A-26C, the second control line guide 2640B may be disposed
adjacent to the first control line arm 2620A and/or the second control line arm 2620B.
For example, the second control line guide 2640B may be disposed between the first
control line arm 2620A and the second control line arm 2620B at the end of the first
control line arm 2620A and the second control line arm 2620B coupled to the base 2610
of the apparatus 2600. This arrangement may facilitate reeving the control line 2602
along a floor, and then reeving the control line 2602 up the second control line guide
2640B towards the first control line guide 2640A.
[0137] In addition to the apparatus 2600 having the first control line arm 2620A and/or
the second control line arm 2620B, the apparatus 2600 may include one or more support
members to help support, guide, and facilitate movement of the components of the apparatus
2600. For example, with respect to Fig. 26A, the apparatus 2600 may include a first
support member 2630A, a second support member 2632A, and/or a third support member
2634A. The first support member 2630A may be coupled between the first control line
arm 2620A and the base 2610, such as by having the first support member 2630A rotatably
coupled to the first control line arm 2620A and rotatably coupled to the base 2610.
[0138] Further, one or more of the support members may be disposed in parallel with respect
to each other and/or with respect to the control line arms of the apparatus. For example,
as shown particularly in Fig. 26A, the second support member 2632A may be disposed
in parallel with respect to the first support member 2630A, and the third support
member 2634A may be disposed in parallel with respect to the first control line arm
2620A. The second support member 2632A may be coupled between the base 2610 and the
third support member 2634A, such as by having the second support member 2632A rotatably
coupled to the base 2610 and rotatably coupled to the third support member 2634A.
The third support member 2634A may be coupled between the second support member 2632A
and the first control line arm 2620A, such as by having the third support member 2634A
coupled to the first control line arm 2620A adjacent the end thereof and/or adjacent
the first control line guide 2640A.
[0139] As discussed above, the apparatus 2600 may include one or more control line arms.
As such, in an embodiment in which the apparatus 2600 includes the first control line
arm 2620A and the second control line arm 2620B, the second control line arm 2620B
may include one or more support members coupled thereto for support. For example,
similar to the support members shown coupled to the first control line arm 2620A,
the apparatus 2600 may include a fourth support member 2630B, a fifth support member
2632B, and/or a sixth support member 2634B. The fourth support member 2630B may be
coupled between the second control line arm 2620B and the base 2610, such as by having
the fourth support member 2630B rotatably coupled to the second control line arm 2620B
and rotatably coupled to the base 2610.
[0140] Furthermore, the fifth support member 2632B may be disposed in parallel with respect
to the fourth support member 2630B, and the sixth support member 2634B may be disposed
in parallel with respect to the second control line arm 2620B. The fifth support member
2632B may be coupled between the base 2610 and the sixth support member 2634B, such
as by having the fifth support member 2632B rotatably coupled to the base 2610 and
rotatably coupled to the sixth support member 2634B. The sixth support member 2634B
may be coupled between the fifth support member 2632B and the second control line
arm 2620B, such as by having the sixth support member 2634B coupled to the second
control line arm 2620B adjacent the end thereof and/or adjacent the first control
line guide 2640A.
[0141] In addition to having one or more support members to help support, guide, and facilitate
movement of the components of the apparatus 2600, the apparatus 2600 may also include
one or more links included therein to help support and couple the components of the
apparatus 2600. As discussed above, the link 2646 may be disposed between the first
control line arm 2620A and the second control line arm 2620B. Further, as shown in
Fig. 26A, the apparatus 2600 may include a first link 2636A and/or a second link 2638A.
The first link 2636A may be disposed between the end of the first support member 2630A
and the end of the second support member 2632A and/or the end of the third support
member 2634A, thereby coupling the first support member 2630A with the second support
member 2632A and/or the third support member 2634A. Further, the second link 2638A
may be disposed between the end of the first control line arm 2620A and the end of
the third support member 2634A, thereby coupling the first control line arm 2620A
to the third support member 2634A.
[0142] Similarly, in an embodiment having a second control line arm 2620B, as shown in Figs.
26B and 26C, the apparatus 2600 may include a third link 2636B and/or a fourth link
2638B. The third link 2636B may be disposed between the end of the fourth support
member 2630B and the end of the fifth support member 2632B and/or the end of the sixth
support member 2634B, thereby coupling the fourth support member 2630B with the fifth
support member 2632B and/or the sixth support member 2634B. Further, the fourth link
2638B may be disposed between the end of the second control line arm 2620B and the
end of the sixth support member 2634B, thereby coupling the second control line arm
2620B to the sixth support member 2634B.
[0143] As shown and discussed above, multiple elements within the present disclosure may
be rotatably coupled to each other and/or rotatable with respect to each other. As
such, an apparatus in accordance with the present disclosure may include one or more
hinges, pins, and/or any other rotatable device known in the art to rotatably couple
components to each other. For example, as shown in Fig. 26A, one or more pins 2648
may be disposed through and/or between various components and elements of the apparatus
2600 to rotatably couple the components or elements to each other.
[0144] Referring now to Figs. 27A-27F, multiple perspective views of the apparatus 2600
and a method to attach a control line to the tubular member 2604 in accordance with
one or more embodiments of the present disclosure are shown. Fig. 27A shows the apparatus
2600 in the raised position, in which the first control line guide 2640A coupled to
the first control line arm 2620A and/or the second control line arm 26020B may be
disposed adjacent to the tubular member 2604. This raised position may facilitate
attaching a control line that is guided with the first control line guide 2640A to
the tubular member 2604.
[0145] Fig. 27B shows the apparatus 2600 in an intermediate position between the raised
position and the collapsed position, thereby lowering the first control line arm 2620A
and/or the second control line arm 26020B with the first control line guide 2640A
with respect to the tubular member 2604. Fig. 27C then shows the apparatus 2600 in
the collapsed position, in which the apparatus 2600 has been lowered adjacent to the
floor to facilitate access to the tubular member 2604. In Fig. 27C, and also shown
in Fig. 27D, the apparatus 2600 has moved into the collapsed position, in which the
first control line guide 2640A is disposed adjacent to a tubular gripping and/or support
apparatus 2660. The tubular gripping and/or support apparatus 2660 may be any device
or apparatus capable of gripping and/or supporting a tubular member and/or a string
of tubular members. Such a device or apparatus may include a spider, a collar load
support system, and/or any other device or apparatus known in the art. As such, in
Figs. 27C and 27D, the first control line guide 2640A may be disposed adjacent the
tubular gripping and/or support apparatus 2660 to have a control line run from the
first control line guide 2640A into and through the tubular gripping and/or support
apparatus 2660.
[0146] Referring now to Figs. 27E and 27F, multiple perspective views of the apparatus 2600
in the collapsed position are shown. The apparatus 2600 may be movable to the collapsed
position to facilitate access to the tubular member 2604. As such, when in the collapsed
position, a tool or apparatus, such as power tongs 2662, may be disposed adjacent
to the tubular member 2604. The power tongs 2662 may be used to couple or de-couple
the tubular member 2604 with an additional tubular member 2606, such as by rotating
the tubular members 2604 and 2606 with respect to each other. As such, the power tongs
2662 may be used to make-up and/or break-out threaded connections of tubular members
2604 and 2606 with respect to each other. As shown, the power tongs 2662 may be disposed
on one or more rails 2664 to facilitate movement of the power tongs 2662 with respect
to the tubular members 2604 and 2606 and/or the tubular gripping and/or support apparatus
2660.
[0147] Referring now to Figs. 28A-28C, multiple perspective views of the apparatus 2600
and a system to attach a control line to the tubular member 2604 in accordance with
one or more embodiments of the present disclosure are shown. As shown in Fig. 28A,
the apparatus 2600 is shown in the collapsed position, and the power tongs 2662 are
disposed adjacent to the apparatus 2600 at an end of the rails 2664 at a distance
from the tubular gripping and/or support apparatus 2660. The rails 2664 may then be
removably disposed on the floor 2670, depending on the configuration and sizing requirements
to support and handle the tubular member 2604.
[0148] As such, the rails 2664 may be removed, along with the power tongs 2662, such that
an additional tool or apparatus may be disposed adjacent to the tubular member 2604.
Accordingly, as shown in Figs. 28B and 28C, the rails 2664 may be removed to enable
access to one or more tracks 2666. The tracks 2666 may be used to dispose an additional
tool or apparatus adjacent to the tubular member 2604. For example, additional power
tongs 2668, which may be sized to couple or de-couple tubular members of different
sizes as compared to power tongs 2662, may use the tracks 2666. The additional power
tongs 2668 may be disposed on one or more tracks 2666 to facilitate movement of the
additional power tongs 2668 with respect to the tubular member 2604 and/or the tubular
gripping and/or support apparatus 2660.
[0149] As shown and discussed above, an apparatus in accordance with one or more embodiments
of the present disclosure may include a base, such as the base 2610 having tracks
2612 formed thereon and/or attached thereto. However, those having ordinary skill
in the art will appreciate that a base in accordance with the present disclosure may
include only the tracks 2612 and/or similar structure to have the one or more control
line arms rotatably coupled thereto, with the tracks 2612 then connected to a floor.
For example, tracks 2612 may be directly connected to a floor of a drilling rig, as
compared to connecting the tracks 2612 to the base 2610, and then disposing the base
2610 on the floor. Similarly, the one or more support members of the present disclosure
need not be connected directly to a base, and instead may be coupled to the floor
when supporting the apparatus of the present disclosure.
[0150] Further, the present disclosure contemplates having one or more actuators coupled
to one or more components of the apparatus 2600 to impart movement thereto, as desired.
For example, an actuator may be coupled between one or more of the control line arms
and the base to impart movement to the control line arms with respect to the base.
This arrangement may enable the apparatus 2600 to be movable between the raised position
and the collapsed position. As such, an actuator used in accordance with one or more
embodiments disclosed herein may be a hydraulic, pneumatic, electric, and/or any other
actuator known in the art. An actuator may be remotely controlled. Further, those
having ordinary skill in the art will appreciate that other arrangements for an actuator
to move one or more components of an apparatus in accordance with embodiments disclosed
herein may be used without departing from the scope of the present disclosure.
[0151] Referring now to Figs. 29A-29C, multiple perspective views of the tubular gripping
and/or support apparatus 2660 in accordance with one or more embodiments of the present
disclosure are shown. Fig. 29A shows a top down view of the tubular gripping and/or
support apparatus 2660, which may be a spider, as shown, having slips that are disposed
downward within a bowl and in a closed position. As shown, the tubular gripping and/or
support apparatus 2660 may have one or more openings 2672 formed therethrough, such
as a "keyhole" formed therethrough from a top side to a bottom side of the tubular
gripping and/or support apparatus 2660. Fig. 29B then shows a side perspective view
of the slips of the tubular gripping and/or support apparatus 2660 disposed upward
within the bowl and in an open position, and Fig. 29C shows a side perspective view
of the slips of the tubular gripping and/or support apparatus 2660 disposed downward
within the bowl and in the closed position. As such, the control line 2602 may be
disposed within an opening 2672 of the tubular gripping and/or support apparatus 2660
such that the control line 2602 may pass through the tubular gripping and/or support
apparatus 2660 without damage.
[0152] As such, referring now to Figs. 30A-30C, and also as shown in Figs. 26A-26C and Figs.
27A-D, the apparatus 2600 may include a docking chute 2650 to facilitate passing one
or more control lines from the apparatus 2600 and into and through the tubular gripping
and/or support apparatus 2660. As shown in the figures, the docking chute 2650 may
be a tube or cylinder, or any other framework that may at least partially enclose
a control line, and may be disposed adjacent an end of the control line arms 2620
of the apparatus 2600. In particular, as shown in Figs. 26A-26C and Figs. 27A-D, the
docking chute 2650 may be coupled, such as rotationally coupled, to an end of the
first control line guide 2640A having the plurality of rollers 2642 (shown in Figs.
30A-30C). In one or more embodiments, a side edge, such as a backside edge, of the
docking chute 2650 may be disposed in a tangential alignment with the roller 2642
of the first control line guide 2640A disposed closest and adjacent to the docking
chute 2650. Further, in one or more embodiment, the docking chute 2650 may additionally,
or alternatively, include one or more rollers to facilitate movement and passing of
the control line 2602 therethrough.
[0153] As the control line arms 2620 move within the apparatus 2600, such as when the apparatus
2600 moves between the raised position and the collapsed position, the docking chute
2650 may be able to rotate and articulate with respect to the control line arms 2620
and/or the first control line guide 2640A. Thus, independent of the movement of the
control line arms 2620 and the apparatus 2600 altogether, the docking chute 2650 may
maintain a downward alignment to facilitate handling of the control line 2602. Further,
one or more actuators may be coupled to the docking chute 2650, such as coupled between
the docking chute 2650 and one or more components of the apparatus 2600
(e. g., control line arms 2620, first control line guide 2640A), to control movement of the
docking chute 2650 with respect to the apparatus 2600, as desired.
[0154] In Figs. 30A-30C, and also in Figs. 27A-27D, the docking chute 2650 is shown moving
into and docking within the tubular gripping and/or support apparatus 2660, such as
within the opening 2672 of the tubular gripping and/or support apparatus 2660, as
the apparatus 2600 and control line arms 2620 move from the raised position to the
collapsed position. Once the docking chute 2650 has been disposed within the opening
2672 of the tubular gripping and/or support apparatus 2660, the slips of the tubular
gripping and/or support apparatus 2660 may be moved from an upward position to a downward
position to externally grip the tubular member 2604. As the control line 2602 is disposed
within and at least partially enclosed within the docking chute 2650, the control
line 2602 may be protected from any damage that may be imparted thereto from the movement
of the internal components of the tubular gripping and/or support apparatus 2660 when
gripping the tubular member 2604. As such, Fig. 30A shows the docking chute 2650 entering
into the opening 2672 of the tubular gripping and/or support apparatus 2660, Fig.
30B shows the docking chute 2650 disposed within the opening 2672 of the tubular gripping
and/or support apparatus 2660 with the slips still in an upward position, and Fig.
30C shows the docking chute 2650 disposed within the opening 2672 of the tubular gripping
and/or support apparatus 2660 with the slips in downward position to grip and/or support
the tubular member 2604.
[0155] Referring now to Fig. 31, a side perspective view of an apparatus 3100 having a control
line arm 3120 moving between a raised position and a collapsed position in accordance
with one or more embodiments of the present disclosure is shown. The control line
arm 3120 may include a control line guide 3140 disposed and/or coupled to an end thereof,
such as by having the control line guide 3140 rotationally and/or pivotally coupled
to the end of the control line arm 3120. Further, the control line guide 3140 may
include a plurality of rollers 3142 included therein to facilitate handling and movement
of a control line 3102 therethrough. As the control line arm 3120 and the apparatus
3100 moves between the raised position and the collapsed position, the control line
guide 3140 may be able to rotate and articulate with respect to the control line arm
3120. Thus, independent of the movement of the control line arm 3120 and the apparatus
3100 altogether, the control line guide 3140 may maintain a downward alignment to
facilitate handling of the control line 3102.
[0156] Referring now to Fig. 32, a side view of a control line guide 3240 in accordance
with one or more embodiments of the present disclosure is shown. The control line
guide 3240 may be used to articulate with a control line 3202, such as when the control
line 3202 is moved within the apparatus 2600 between the raised position and the collapsed
position. As shown, the control line guide 3240, which may be used as the second control
line guide 2640B in Figs. 26A-26C, may include a plurality of rollers 3242 to facilitate
movement of the control line 3202 through the control line guide 3240. Further, the
control line guide 3240 may include one or more movable segments 3244, such as movably
and/or rotatably coupled to a body of the control line guide 3240 and/or coupled to
each other.
[0157] For example, as shown in Fig. 32, one or more of the segments 3244 may be rotatably
and/or pivotally coupled to an end of the body of the control line guide 3240, in
which subsequent additional segments 3244 may then be rotatably and/or pivotally coupled
to each other such that the control line guide 3240 may be able to articulate with
the movement of the control line 3202. As such, when the apparatus 2600 is in the
raised position, the control line guide 3240 may be in a upward position when guiding
the control line 3202 therethrough, and when the apparatus 2600 is in the collapsed
position, the control line guide 3240 may be in a downward position when guiding the
control line 3202 therethrough. Further, one or more of the segments 3244 may include
a hard stop 3246, such as disposed on a top side thereof, as shown, may be used to
prevent or limit movement of the segments 3244 with respect to each other. This may
enable the hard stops 3246 to engage adjacent surfaces of the segments 3244 and the
control line guide 3240 to prevent any damage to the control line 3202 by maintaining
an appropriate bend radius for the control line 3202 when disposed within the control
line guide 3240.
[0158] It should be understood that a "control line," as used herein, may refer to any type
of line, cord, umbilical, cable, tube, hose, wire, flat pack, and/or any other similar
structure or device that may be attached to a tubular member and used to transmit
electrical power and/or signals along the tubular member downhole. For example, a
control line, which may be known as having an outer diameter between about 0.25 inches
to about 0.75 inches (about 0.64 cm to about 1.9 cm), may not be so limited. For example,
a control line, as used herein, may also be known in the present disclosure to encompass
flat packs, which may include two to three lines therein, and/or may also be known
in the present disclosure to encompass umbilicals, which may include multiple lines
therein and may have an outer diameter between about 1.5 inches to about 4 inches
(about 3.8 cm to about 10 cm).
[0159] An example of the respective control lines is shown in Fig. 33, thereby showing the
different configurations and sizes of control lines that may be used in accordance
with the present disclosure. As such, the present disclosure not only contemplates
being able to be used in conjunction with each of these different types of control
lines, but in fact may be used to control multiple control lines having the same or
varied sizes or configurations. Further, it should be understood that the different
types of control lines used herein may have different bend radiuses. For example,
in one or more embodiments, the bend radiuses may vary be between about 12 inches
(about 30.5 cm), and up to about 34 feet (about 10.4 m), at least. Accordingly, the
present disclosure contemplates being able to use and guide control lines having all
types of shapes, sizes, and configurations, in addition to controlling one or more
of these varied types of control lines.
[0160] Referring now to Figs. 34A-34D, multiple views of a control line guide 3400 in accordance
with one or more embodiments of the present disclosure are shown. Fig. 34A shows a
top down view of the control line guide 3400, Fig. 34B shows a top down view of a
second outer wing control line guide 3432, Fig. 34C shows a side view of the control
line guide 3400, and Fig. 34D shows a cross-sectional view across the second outer
wing control line guide 3432. As discussed above, more than one control line, and
more than one size/configuration of control line, may be used in accordance with one
or more embodiments of the present disclosure. As such, when attaching multiple control
lines to a tubular member, a control line guide, such as that shown in Figs. 34A-34D,
may be used in accordance with one or more embodiments disclosed herein.
[0161] The control line guide 3400 may include a body 3410 with a first arm 3420 coupled
to and/or extending from one side of the body 3410 and a second arm 3430 coupled to
and/or extending from another/opposite side of the body 3410. The body 3410 may include
one or more rollers 3412, such as by including a first roller 3412A and a second roller
3412B, in which at least one of the rollers 3412, such as the first roller 3412A,
may include one or more grooves formed therein to facilitate handling and guiding
of the control lines therethrough. Further, the first arm 3420 may have a first outer
wing control line guide 3422 rotationally and/or pivotally coupled thereto, and the
second arm 3430 may have a second outer wing control line guide 3432 rotationally
and/or pivotally coupled thereto.
[0162] The first outer wing control line guide 3422 may include one or more rollers 3424,
such as by including a first roller 3424A and a second roller 3424B, in which at least
one of the rollers 3424, such as the first roller 3424A as shown, may include one
or more grooves formed therein to facilitate handling and guiding of the control lines
therethrough. Similarly, the second outer wing control line guide 3432 may include
one or more rollers 3434, such as by including a first roller 3434A and a second roller
3434B, in which at least one of the rollers 3434, such as the first roller 3434A as
shown, may include one or more grooves formed therein to facilitate handling and guiding
of the control lines therethrough.
[0163] As shown, the control line guide 3400 may be used to handle and guide control lines
of multiple sizes and configurations. For example, as shown in Fig. 34A, in particular,
the body 3410 may be used to handle and guide control lines having larger sizes, as
compared to that of the first outer wing control line guide 3422 and/or the second
outer wing control line guide 3432. Further, the body 3410, the first outer wing control
line guide 3422, and/or the second outer wing control line guide 3432 may be used
to handle and guide control lines having different configurations. As shown in Fig.
34A, the first outer wing control line guide 3422, and/or the second outer wing control
line guide 3432 may be able to handle and guide control lines having circular cross-sections,
as well as rectangular cross-sections. As such, the grooves in one or more of the
rollers of the control line guide may be formed and sized to particularly accommodate
one or more control lines having particular shapes or sizes, and/or any other configurations.
[0164] As the control line guide 3400 includes the first outer wing control line guide 3422
and/or the second outer wing control line guide 3432 rotationally and/or pivotally
coupled thereto, the first outer wing control line guide 3422 and/or the second outer
wing control line guide 3432 may be movable between an open position and a closed
position. In the closed position, as shown particularly in Fig. 34A, the first outer
wing control line guide 3422 and the second outer wing control line guide 3432 may
be folded and disposed inwards with respect to the body 3410. The first outer wing
control line guide 3422 and the second outer wing control line guide 3432 may be disposed
in the closed position when the control line guide 3400 is disposed away from a tubular
member, such as when not being used to currently attach one or more control lines
to a tubular member.
[0165] Then, when desired to attach one or more control lines to a tubular member, the first
outer wing control line guide 3422 and the second outer wing control line guide 3432
may rotate from the closed position to the open position, in which the first outer
wing control line guide 3422 and the second outer wing control line guide 3432 may
rotate by about 90 degrees with respect to the body 3410. In the open position, the
first outer wing control line guide 3422 and the second outer wing control line guide
3432 may be extended and disposed outwards with respect to the body 3410. The first
outer wing control line guide 3422 and the second outer wing control line guide 3432
may be disposed in the open position when the control line guide 3400 is disposed
adjacent to a tubular member.
[0166] The first arm 3420 and the second arm 3430 may or may not be symmetric with respect
to each other. For example, as shown in Figs. 34A-34D, the first arm 3420 and the
second arm 3430 may not be symmetric with each other, in which the first arm 3420
may be longer than the second arm 3430. Further, the first arm 3420 may be disposed
at a different height with respect to the second arm 3430 on the body 3410. For example,
as shown in Figs. 34A-34D, the first arm 3420 may be disposed higher and above the
second arm 3430, thereby enabling the first outer wing control line guide 3422 and
the second outer wing control line guide 3432 to rotate and move along different planes
with respect to each other. These arrangements of the first arm 3420 and the second
arm 3430 may enable control lines to be fed and guided through each of the first outer
wing control line guide 3422 and the second outer wing control line guide 3432, respectively,
without either of the outer wing control line guides interfering with and/or contacting
the control lines when being grasped and controlled by the respective outer wing control
line guide.
[0167] Referring now to Fig. 34D, a cross-sectional view across the second outer wing control
line guide 3432 is shown, in which the second outer wing control line guide 3432 is
disposed in the open position guiding a control line 3402 adjacent a tubular member
3404. The control line 3402 may be guided between the first roller 3434A and the second
roller 3434B of the second outer wing control line guide 3432. Further, the control
line guide 3400 may include one or more auxiliary arms 3440 having one or more rollers
3442 coupled thereto. As shown in Fig. 34D, an auxiliary arm 3440 may be disposed
on a bottom side and below the second outer wing control line guide 3432, in which
the roller 3442 rotatably coupled to an end of the auxiliary arm 3440 may be used
to guide and push the control line 3402 radially and adjacent the tubular member 3404.
As shown, the auxiliary arm 3440 may be rotatably coupled to the control line guide
3400, such as rotatably coupled to the second outer wing control line guide 3432.
One or more auxiliary arms with rollers coupled thereto may also be similarly used
with the first outer wing control line guide 3422 and/or the body 3410.
[0168] As the outer wing control line guides and the auxiliary arms used in conjunction
with the control line guide may be movable and rotatable within the control line guide,
one or more actuators may be included within the control line guide to facilitate
movement of the outer wing control line guides and the auxiliary arms. For example,
as shown in Fig. 34A, an actuator 3450 may be coupled between the first outer wing
control line guide 3422 and the first arm 3420 or the body 3410 such that the actuator
may provide movement to the first outer wing control line guide 3422 with respect
to the first arm 3420. One or more actuators may also be similarly used with the second
outer wing control line guide 3432. Further, as shown in Fig. 34D, an actuator 3450
may be coupled between the second outer wing control line guide 3432 and the auxiliary
arm 3440 such that the actuator may provide movement to the auxiliary arm 3440 with
respect to the second outer wing control line guide 3432. One or more actuators may
also be similarly used with other auxiliary arms.
[0169] Depending on the size, shape, number, and configuration of the control lines used
with the control line guide, the control line guide may have one or more components
that are removable and/or replaceable. For example, in an embodiment in which smaller
control lines may be used, outer wing control line guides and/or only the rollers
of the outer wing control line guides having smaller grooves to correspond with the
smaller control lines may be used and/or replaced within the control line guide. As
such, the present disclosure contemplates multiple embodiments for a control line
guide to accommodate, handle, and guide different sizes, shapes, numbers, and configurations
of control lines.
[0170] Referring now to Fig. 35, a system 3500 to handle, guide, and attach one or more
control lines 3502 to a tubular member 3504 in accordance with one or more embodiments
of the present disclosure is shown. In Fig. 35, multiple levels A-H are shown when
using the system 3500 to guide and attach the control lines 3502 to the tubular member
3504. At level H, a control line guide 3510, such as similar to the control line guide
3400 shown in Figs. 34A-34D or other control line guide discussed above, may be used
to guide the control lines 3502. The control line guide 3510 may be moved from a removed
position, such as away from the tubular member 3504, to adjacent the tubular member
3504 to facilitate attaching the control lines 3502 to the tubular member 3504. As
the control line guide 3510 is moved adjacent the tubular member 3504, the outer wing
control line guides may move from the closed position to the open position, if so
equipped, to move and guide the control lines into the desired arrangement and placement
about the tubular member 3504.
[0171] A control line guide 3520 may be used at level E, such as above a tubular gripping
and/or support apparatus 3530, and additionally and/or alternatively may be used below
the tubular gripping and/or support apparatus 3530. The control line guide 3520 may
include a body 3522 having one or more fingers 3524 rotatably and/or pivotally coupled
thereto between an open position and a closed position. In the open position, the
fingers 3524 may form an opening to receive the control lines 3502 into the control
line guide 3520. Then, in the closed position, the fingers 3524 may enclose about
the control lines 3502 such that the control lines 3502 are retained within the control
line guide 3520. In the closed position, the control line guide 3520 may be selectively
moved towards and/or away from the tubular member 3504 such that the control lines
3502 pass through the tubular gripping and/or support apparatus 3530 without any damage
when in use. The control line guide 3540 may include one or more actuators to facilitate
movement of the fingers 3524 with respect to the body 3522. Additionally or alternatively
to the control line guide 3520, a control line sleeve may be used, such as disposed
within and/or through the tubular gripping and/or support apparatus 3530, to selectively
move and position the control lines 3502 in the tubular gripping and/or support apparatus
3530.
[0172] Further, at levels G and F, one or more auxiliary arms 3540 having one or more rollers
3542 may be used to facilitate any desired movements of the control lines 3502. As
shown at level G, the auxiliary arm 3540 may be coupled to and/or movable with respect
the control line guide 3510, and as shown at level F, the auxiliary arm 3540 may be
coupled to and/or movable with respect to the control line guide 3540. The auxiliary
arms 3540 may include one or more actuators to enable movement. For example, the auxiliary
arms 3540 may be extendable to selectively push and guide the control lines 3502 toward
and away from the tubular member 3504.
[0173] At levels C, B, and A, the control lines 3502 gradually move closed and into the
desired arrangement about the tubular member 3504. Once the control lines 3502 are
within the desired arrangement and configuration about the tubular member 3504, the
control lines 3502 may be attached to the tubular member 3504 using a clamp 3506,
such as shown at level A. The size and shape of the clamp 3506 may then depend on
the number, size, and configuration of control lines about the tubular member 3504.
[0174] Referring now to Fig. 34D, a cross-sectional view across the second outer wing control
line guide 3432 is shown, in which the second outer wing control line guide 3432 is
disposed in the open position guiding a control line 3402 adjacent a tubular member
3404. The control line 3402 may be guided between the first roller 3434A and the second
roller 3434B of the second outer wing control line guide 3432. Further, the control
line guide 3400 may include one or more auxiliary arms 3440 having one or more rollers
3442 coupled thereto. As shown in Fig. 34D, an auxiliary arm 3440 may be disposed
on a bottom side and below the second outer wing control line guide 3432, in which
the roller 3442 rotatably coupled to an end of the auxiliary arm 3440 may be used
to guide and push the control line 3402 radially and adjacent the tubular member 3404.
As shown, the auxiliary arm 3440 may be rotatably coupled to the control line guide
3400, such as rotatably coupled to the second outer wing control line guide 3432.
One or more auxiliary arms with rollers coupled thereto may also be similarly used
with the first outer wing control line guide 3422 and/or the body 3410.
[0175] An apparatus, a method, and/or a system in accordance with the present disclosure
may be helpful in multiple areas, such as within the oil and gas industry. For example,
an apparatus in accordance with the present disclosure may be used to facilitate attaching
a control line to a tubular member. Further, the present disclosure may be used to
provide selective access to a tubular member when adding and/or removing tubular members
to a tubular string, such as by making-up and/or breaking-out connections between
tubular members within the tubular string. Further, the present disclosure may be
used to selectively distance a control line away from a tubular member, such as disposing
a control line within a control line pathway of a tubular gripping and/or supporting
apparatus, when the tubular gripping and/or support apparatus is in use and is gripping
and/or supporting one or more tubular members therein.
