摘要： The invention relates to a device for landing or retrieving a pipeline end on the seabed, the device comprising an outboard connecting part (2) being adapted to connect with the pipeline end and lowered from the surface towards a landing structure (3) on the seabed or alternatively lifted from the landing structure (3) on the seabed towards the sea surface. The invention is distinctive in that the outboard connecting part (2) comprising a pair of guide funnels (5a, 5b) adapted to engage with a pair of corresponding guideposts (4a, 4b) arranged on the landing structure (3), at least one fin (8) is attached to the outboard connecting part (2) and is adapted to bear against the landing structure (3), said pair of guide funnels (5a, 5b) are adapted to be in contact with the corresponding pair of guideposts (4a, 4b) when the outboard connecting part (2) is resting on the landing structure (3).

摘要： A lifting device for lowering a pipeline end from a water surface to a seabed, alternatively later retrieval of the same from the seabed to the water surface, said pipeline end being provided with an outboard connecting part designed for mating and connection with an inboard connecting part on the seabed. The lifting device includes a hang off clamp adapted for connection with the outboard connecting part, at least one lifting arm pivotably connected to the hang off clamp at a respective first end of said at least one lifting arm and a yoke, said yoke being adapted to be releasable connected to the at least one lifting arm at a respective second end of said lifting arm, said at least one lifting arm having a locking arrangement for securing the at least one lifting arm to the hang off clamp in a non-rotational resting position. A method for lowering of a pipeline end from a water surface and retrieving a pipeline end from a seabed by use of the lifting device is also disclosed.
