摘要： A tendon element (36) is cooperable with other tendon elements to form an abandonment or recovery string. The tendon element (36) is elongate to define opposed ends, and comprises: complementary connector formations (62, 64) at respective ends, each connector formation being cooperable, in use when forming a string, with a complementary connector formation of a neighbouring tendon element (36) in the string; a tensile load-bearing member (66) extending between the connector formations; and at least one sleeve (68) removably mounted around the load-bearing member. The sleeve (68) is arranged to be handled by pipe-joint handling apparatus associated with a J-lay tower.

摘要： A hydraulically-powered subsea tool system has a tool (26) and a tool power unit (12). The tool (26) communicates with a first connector element (30) on a hydraulic drive circuit (82). The tool power unit (12) has a hydraulic supply circuit (88) communicating with a second connector element (20). The connector elements are wet-mated with each other to connect the circuits for powering the tool. The circuits are pressure-compensated by respective compensators (136,90). When the circuits are connected, a valve (140) is operable to transfer pressure compensation of one of the circuits from the compensator (136) of that circuit to the compensator (90) of the other circuit. The valve (140) suitably transfers pressure compensation of the drive circuit from a drive circuit compensator to a supply circuit compensator.

摘要： A method of coating a field joint of a pipeline places at least one body having a thermoplastics material around the field joint. The body is heated in a mould cavity around the field joint to effect thermal expansion of the thermoplastics material. Thermal expansion of the body in the mould cavity is constrained to apply elevated pressure between the body and pipe sections joined at the field joint. The elevated pressure improves bonding and fusing between the body, which forms a field joint coating, and the parent coatings and the exposed pipe sections of the pipe joints. The body need not be fully molten, which reduces the mould residence time including in-mould heating and cooling phases.

摘要： A pipe-bending rig has an anchorage for holding a proximal end of a pipe and a bending former that presents a convex forming surface toward a side of a pipe when the pipe is held by the anchorage to extend distally from the anchorage. A pipe-bending drive exerts lateral force on the pipe to deflect a distal end of the pipe, which effects plastic bending of the pipe along its length against the forming surface. A carriage is movable along a path with respect to the anchorage and the bending former during deflection of the distal end of the pipe. A link carried by the carriage applies distal force to the pipe to impart longitudinal tension to the pipe as the pipe is being bent against the forming surface.

摘要： A subsea-replaceable fuse assembly has at least one fuse and a wet-mateable fuse connector element. The connector element is arranged to connect the fuse assembly to a subsea electrical load requiring protection of the fuse. The fuse connector element has conductor elements that are electrically connected to the fuse. A corresponding method of protecting a subsea electrical load includes connecting a fuse to the load underwater in a wet-mating operation effected between connector elements that are electrically connected, respectively, to the fuse and to the load.

摘要： A method provides power to a subsea equipment electrical system underwater, without a wet-mated electrical connection. The method includes temporarily coupling a rotary coupling element of a power source to the subsea equipment and turning that element to generate electric power on board the equipment. Subsea equipment that implements the method comprises: an on-board electric power generator connected to an electrical load such as a rechargeable battery to charge the battery when the generator is driven; and a rotary coupling element that is turned by an external drive to drive the generator. Alternative subsea equipment to implement the method comprises: a stator, but not a rotor, of an on-board electric power generator, which supplies current to the load when an externally-driven rotor is positioned adjacent to the stator and turned relative to the stator. A power source having a generator rotor is docked with the equipment for this purpose.
