Abstract
A subsea hanging device comprises a hanging frame 1 adapted to support an assembly (such as a gooseneck 3 and a subsea connector 4 being used to attach a heavy pipe 7 to a pipe hub 11 on the seabed), a hanging eye 8 which slides on said frame when a shaft 10 threaded through it is axially rotated, and a ROV drive bucket 12 attached to one end of the shaft. A guide funnel 13, 16 pivoted to the frame and adapted to fit over a guide post 17 on the seabed actuates a pointer 15 which indicates on a scale 14 whether the hanging angle needs adjustment to enable the connector 4 to be engaged with the hub 11.
