Abstract: A modular anchor comprising: a top cross, wherein the top cross comprises a central tubular pile and one or more arm attachment tubulars and one or more cross arms connected to the one or more arm attachment tubulars and associated methods and systems.

Abstract: A pipe-laying vessel (1) is provided, including a tower (2) extending upwardly from the vessel, a pipe loading arm (9) for raising a length of pipe from the deck to a position aligned with the tower, a travelling clamp assembly (30) mounted for movement along the tower. The pipe-laying vessel may include a fixed clamp assembly (60) located in the region of a lower portion of the tower, wherein the travelling clamp assembly and/or the fixed clamp assembly includes both a friction clamp (34, 63) and a collar clamp (62), each of the friction clamp and the collar clamp being movable between an operative position, in which it is adjustable between a clamping and a released position, and an inoperative position. Alternatively or additionally the travelling clamp assembly (30) includes both a line-up clamp (33) and a pipeline tension bearing clamp (34).

Abstract: A subsea buoy comprising: a frame comprising one or more winches and a subsea equipment attachment point and one or more buoyancy modules attached to the frame and associated systems and methods.

Abstract: A pipe-laying vessel is provided, including a tower extending upwardly from the vessel, a pipe loading arm for raising a length of pipe from the deck to a position aligned with the tower. The pipe-laying vessel may also include a support assembly for supporting a bulky item to be accommodated along the pipeline, the support assembly including a frame pivotable between a first load receiving position and a second tilted position in which it extends approximately parallel to the tower, and drive means for pivoting the tiltable frame between its first and second positions. The pipe-laying vessel may alternatively or additionally include a welding assembly station cabin in the region of a lower portion of the tower, a movable support assembly for supporting a bulky item to be accommodated along the pipeline, the movable support assembly being disposed on top of the cabin.
