[0001] The present invention is concerned with a water vessel. In particular a water vessel
which is suitable for removing debris, pollution or the like from a body of water,
such as a marina, harbour, canal or the like.
[0002] Waterways such as canals, marinas and harbours are becoming more and more popular
as areas of leisure interest and natural beauty. Cleanliness and environmental management
are critical factors in the standards of services expected from such waterways. However,
a major problem with such waterways is the increasing presence of wind blown debris,
river debris, tidal flotsam, other pollutants (such as oil or the like) and in certain
circumstances, animal carcasses all of which typically float on the surface of the
water. Therefore, the swift removal of debris is essential not only for aesthetic
reasons but also to prevent debris fouling boats and mechanical equipment such as
lock gates.
[0003] In order to remove such debris, personnel have been known to attempt to remove the
debris through the use of nets and/or rakes. Such a method is not only labour intensive
and costly but is also an unpleasant task for the personnel involved.
[0004] Alternatively, the use of a debris collection boat is known. An example of such a
boat is described in GB2287000. The boat described in GB2287000 collects debris in
a front portion and subsequently transfers the collected debris to a holding area
where the debris remains until the boat docks and the debris can be removed. Such
a boat is disadvantageous as complex haulage systems are required.
[0005] It is therefore an aim of the present invention to alleviate at least some of the
disadvantages highlighted above.
[0006] It is a further aim of the present invention to provide apparatus suitable for use
in the removal of debris from a waterway.
[0007] It is yet a further aim of the present invention to provide apparatus suitable for
use in the removal of debris from a waterway which does not include complicated mechanical
or hydraulic systems which may malfunction.
[0008] It is yet a further aim of the present invention to provide a method for the removal
of debris from a waterway.
[0009] It is yet a further aim of the present invention to provide a multi purpose water
vessel arrangement.
[0010] Accordingly, there is provided a modular water vessel arrangement which includes:
a support member, a first module which includes a debris collection means, and a second
module which includes a work station, the support member being arranged to support
the first module which is interchangeable with the second module.
[0011] The use of the term "debris" as used herein refers to any floating debris or pollution,
including windblown debris, river debris, tidal flutsom, animal carcasses, other pollutants
(such as oil), or the like.
[0012] Advantageously, interchanging the first module and the second module change the functionality
of the water vessel arrangement. Advantageously, the arrangement may form a water
vessel which may be used for removal of debris from a waterway when the first module
is supported by the support member. Alternatively, the arrangement may form a water
vessel suitable for use as load carrying boat, as a working or diving platform, for
use when towing, or the like, and also for emergency deployment when the second module
is supported by the support member.
[0013] According to a preferred embodiment of the present invention, the support member
includes buoyancy support means, preferably having a first hull and a second hull,
such as a catamaran type water vessel.
[0014] It is therefore preferred that the first module and/or the second module are shaped
and dimensioned to be positioned substantially between the first hull and the second
hull.
[0015] Typically, the first hull and the second hull are substantially parallel. This feature
has the advantage that the water vessel can be manoeuvred substantially adjacent the
side of a marina, canal, or the like. Furthermore, it is preferred that each hull
has a front portion and a rear portion, the front portion being shaped so as to not
substantially impede movement through a body of water.
[0016] Advantageously, the first module and the second module are removable from the support
member.
[0017] Typically, the first module and/or the second module have lifting attachments attached
thereto so as to assist in removal of each module from the support member. The lifting
attachments are typically hooks and/or loops.
[0018] It is also preferred that each module has at least one connecting portion for releasable
engagement with a corresponding connecting portion arranged on the support member.
It is preferred that each connecting portion on each module is of the same material
as the module. Similarly, it is preferred that each corresponding connecting portion
on the support member is of the same material as the support platform.
[0019] The arrangement may be of aluminium, galvanised steel, plastics or glass reinforced
plastics. However, it is envisaged that the arrangement may be constructed from any
material which provides buoyancy.
[0020] It is particularly preferred that the vessel is constructed from aluminium (such
as marine grade aluminium which is preferred)as this enables the vessel to be lightweight,
have low maintenance costs, and ease of construction. The use of aluminium has the
further advantage that it permits the vessel to be constructed in a number of different
sizes to suit the specific needs of each waterway without the need for expensive moulds.
[0021] The support member, the first module and the second module may be of the same material
(such as aluminium), however, it is envisaged that each component may be of a different
material.
[0022] The arrangement may further include means for moving the support member through a
body of water such as manual means (oars, paddles or the like), by the use of wind
power (for example using sails) or by motor means (which is particularly preferred).
A preferred motor means includes the type known as an outboard motor.
[0023] The debris collection means is preferably arranged to act as a strainer whereby debris
collected in the debris collection means is retained therein whilst permitting liquid
to pass therethrough.
[0024] The first module is preferably in the form of a basket, box or the like. The basket,
box or the like typically includes a base and a plurality of upstanding panels extending
from the base.
[0025] The upstanding panels preferably include three substantially fixed panels. It is
further preferred that the upstanding panels include three substantially fixed panels
and typically one movable panel. The movable panel is preferably movable between a
closed position which substantially inhibits entry of debris into the box and an open
position which substantially permits entry of debris into the box.
[0026] The movement of the movable panel is preferably controlled by control means, such
as a lever (which is typically manually operated).
[0027] It is therefore preferred that the panels are of a mesh-like material, such as aluminium
mesh. It is envisaged that the base may be of a mesh-like material and therefore be
essentially the same as the panels, or the base may be a solid body, such as, for
example an aluminium sheet material.
[0028] It is particularly preferred that the debris collection means is lined with for example,
an oil absorbing material when the debris includes oil. Advantageously, the oil is
retained by the oil absorbing material whilst permitting water to pass through the
debris collection means.
[0029] The second module may be a platform (which may be substantially flat) or may have
an open box configuration, which preferably includes a (preferably solid) base and
four (preferably solid) upstanding walls extending from the base.
[0030] Typically, the base is a controlled closeable base which is movable between a closed
position and an open position which permits contents of the second module to be removed
(typically under gravity) therefrom.
[0031] The second module may be of be of aluminium, galvanised steel, plastics or glass
reinforced plastics. However, it is envisaged that the second module may be constructed
from any material which provides buoyancy.
[0032] It is also envisaged that the work station of the second module has an aperture (which
may have a removable cover) therein which advantageously permits, when in use, access
to a body of water below.
[0033] According to a further aspect of the invention, the second module substantially as
described hereinbefore may be used as a boat when it does not form part of the water
vessel arrangement. Advantageously, a motor, such as an outboard motor, may be attached
to the second module. However, it is also envisaged that the second module may be
powered by the use of wind (for example using a sail) by manual means (for example
using a paddle or an oar).
[0034] In a particularly preferred embodiment of the present invention, the debris collection
means includes a solid plate aluminium base, two side panels (typically of foraminated
aluminium), a front moveable panel of aluminium mesh and a second preferably fixed
rear panel of aluminium mesh.
[0035] It is particularly preferred that the first module further includes a moveable gate
(typically of plate aluminium), arranged to be moveable between an open position to
a closed position which substantially blocks the rear mesh-like panel of the debris
collection means. This feature has the advantage of deflecting propellor wash when
the engine is in reverse gear, so as to prevent debris being washed back out of the
debris collection means.
Preferably, the water vessel arrangement further includes fender means (such as tyres
or the like) arranged about the periphery of the support platform. Advantageously,
the fender means substantially prevents the vessel from being damaged by walls of
a marina, canal or indeed a further vessel in the waterway. A preferred fender means
includes a plurality of wheels.
[0036] Wheels have the added advantage of assisting movement of the vessel when the vessel
is adjacent the walls of the marina, canal or the like.
[0037] According to a further embodiment of the present invention, it is envisaged that
the arrangement includes a plurality of support members, each support member arranged
to support at least one first module and/or at least one second module and the support
members being connected together, preferably in side by side configuration. The support
member, first module and second module are substantially as described hereinbefore.
[0038] According to a further aspect of the present invention, there is provided a water
vessel arrangement which includes a support member, a first module and a second module,
substantially as described hereinbefore, the support member including a receiving
portion arranged to receive the first module and the second module.
[0039] According to yet a further aspect of the present invention, there is provided a water
vessel arrangement comprising a support member, a first module including a debris
collection means, and a second module including a work station, said first and second
modules being arranged for selective attachment to the water vessel so as to configure
the water vessel to perform a respective function.
[0040] According to a further aspect of the present invention, there is provided a water
vessel arranged for the selective attachment thereto of one or more of a plurality
of different modules to configure the water vessel to perform a respective function,
said modules comprising at least a first module including a debris collection means
and a second module including a work station.
[0041] According to yet a further aspect of the present invention, there is provided a method
of removing debris from a waterway, which method includes:
providing a water vessel arrangement substantially as described hereinbefore, the
support member supporting a first module;
manoeuvring the water vessel substantially in the general direction of the debris;
and
trapping the debris in the debris collection means.
[0042] Typically, the method further includes a step whereby the first module including
the debris collection means is removed from the support member, for example by use
of a hoist or crane, or the like. The debris is preferably subsequently removed from
the first module, typically into a debris collection vessel, such as a skip.
[0043] The present invention will now be described by way of example only, with reference
to the accompanying drawings, wherein:
Figure 1 represents buoyancy a support member for use in a water vessel arrangement
according to the present invention;
Figure 2 represents a plan view of the buoyancy support member shown in Figure 1;
Figure 3 represents a first module including debris collection device for use in a
water vessel arrangement according to the present invention;
Figure 4 represents a second module include a work station for use in a vessel according
to the present invention;
Figure 5 represents a side view of the second module shown in Figure 4;
Figure 6 represents an exploded view of a fender for use on the support platform according
to the present invention.
[0044] Referring to Figures 1 and 2, a buoyancy support member is generally identified by
the numeral 1. The support platform 1 comprises a first hull 2 (which is constructed
from marine grade aluminium) which is connected to a second hull 3 (which is also
constructed from marine grade aluminium) by aluminium bridging panels 4, 5 and 6.
[0045] Wheels 7a and 7b, are arranged on first hull 2 and wheels 7c and 7d on the second
hull 3. The wheels 7a, 7b, 7c, and 7d act as fenders for the water vessel.
[0046] Referring to Figure 3, where like numerals have been used to identify like parts
shown in Figures 1 and 2. The debris collection device generally indicated by the
numeral 10, comprises a galvanised steel frame 11, a solid aluminium base 19, two
perforated aluminium side panels 13 and 14, front movable aluminium mesh gate 12 and
rear aluminium mesh panel 13. Movement of the front movable gate 12 is controlled
by lever 5 (which is attached to the frame 11 and gate 12). A hinged flap 16 is arranged
to cover rear panel 13 of the debris collecting basket. Therefore when the vessel
(not shown in Figure 3) is manoeuvred in a backwards direction (indicated by arrow
B) ie reverse thrust on the outboard motor (not shown), flap 16 lies flush against
rear panel 13; the panel has the advantage of preventing the debris collected in the
basket being washed back out of the basket when the vessel is manoeuvred in a backwards
direction (indicated by arrow B) . The frame includes shoulders 17a, 17b, 18a and
18b, which when the debris collection means 10 is in use, rest on hulls 2 and 3 of
the support member(shown in Figures 1 and 2).
[0047] Referring to Figures 4 and 5, where like numerals have been used to identify like
parts shown in Figures 1 to 3. The work station is generally indicated by the numeral
20. The work station 20 includes a hinged aluminium trap door base 21 and four aluminium
wall panels 22, 23, 24 and 25. The work-station further includes shoulders 26a, 26b
and 27b which are arranged to rest on hulls 2 and 3 when the work station forms part
of a water vessel.
[0048] Referring to Figure 6, where like numerals have been used to identify like parts
shown in Figures 1 to 5. The wheel 7a is attached to hull 2 by means of pipe 3 which
is inserted in tube 31. The wheel 7a is secured in place by cap 32.
