Abstract (en)

[origin: WO2014133439A2] The invention relates to a method pertaining to a drilling arrangement (7) comprising a drive member support device (49) for fixing a drive member (13) arranged at the drilling arrangement (7), wherein the drive member (13) operates in a direction (R), the method comprising: - providing a drive head (19) with an axis of rotation (22) adapted for engagement with a drill string means (59), wherein the drive head (19) is arranged to cooperate with a feed member (14; 15) operating in respectively a first (P) and a second (Ρ') direction; - providing the drive head (19) pivotable relative to the drive member support device (49) and the feed member (14; 15) about an axis of rotation (A) extending transverse said direction (R); - pivoting the drive head from a first fixed end position (VI; 26) where the axis of rotation (22) of the drive head is parallel to said direction (R) and the feed member (14; 15) drives the drive head (19) in the first direction (P), to a second fixed end position (V2; 28) where the axis of rotation (22) of the drive head is parallel to said direction (R) and the feed member (14; 15) drives the drive head (19) in the second direction (Ρ'), where the directions (P) and (Ρ') are opposite. The invention also relates to a drilling arrangement and a computer program product comprising program code for an electronic control unit associated with the drilling arrangement for performing the method.
