Abstract
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).
