Abstract:
A submersible tool, adapted for mounting on a ROV, to be used for coupling together subsea pipelines including a first pipeline (2) which initially is located on a sea bottom or in submerged position in the sea, and a second pipeline (12) including a terminator (14) which is preinstalled on a bottom based template or frame (10), which tool (8) is equipped with a gripping device for catching and holding the first pipeline for transport to the second pipeline mounted on the bottom frame,characterized in that the tool (8) is provided with opposed, pivotable clawlike means (40,42) which forcibly may be pivoted between an outer position wherein the claw means can grasp around an intermediately positioned pipeline (2,4) and an inner position wherein the pipeline is seized firmly and directionally stable inside the pivotable claw means,power driven means (56,56) mounted in the tool (8) adjacent the claw means in order to impart in the claw means positioned pipeline (2,4) an axial movement relative to the tool (8),and which tool (8) at the front end is provided with a substantially ringshaped, forcibly pivotable, anchoring head (34) in position concentrially with the axis through the pipeline, which anchoring head (34) is adapted for anchoring in a complementary seat (18) mounted in position in front of said terminator (14) on the second pipeline mounted on the bottom frame (10).
