摘要： A method of installing a subsea pipeline for tie-in to a subsea structure. The method comprises laying, using a pipe laying vessel, an intermediate section of the pipeline on to a pipe restraint device, wherein the pipe restraint device is at or near the subsea structure, or is at or near a location at which a subsea structure will be installed, and the pipe restraint device restricts transverse movement of the pipeline. The intermediate section of the pipeline is configured to be tapped at or near the pipe restraint device for providing fluid communication between the pipeline and the subsea structure.

摘要： A subsea riser is installed by lowering at least one riser conduit to the seabed when piggybacked to an elongate support that comprises at least one flowline. The elongate support may be a pipeline bundle, which may be attached to one or more towheads in a towable bundle unit. The riser conduit may be in fluid communication with the flowline. At the seabed, a free end portion of the riser conduit is detached from the elongate support by releasing subsea-releasable fastenings. Then, with the elongate support and a root end of the riser remaining at the seabed, the detached free end portion of the riser conduit is lifted away from the elongate support to a riser support, such as a platform, an FPSO or a buoy.

摘要： A method of installing a subsea pipeline comprises supporting at least one elongate pipe stalk at the surface of the sea at a first, relatively shallow-water location by virtue of buoyancy added to the pipe stalk. The pipe stalk is then towed at the surface to a second location that is in deeper water. There, with the pipe stalk supported between leading and trailing towing vessels, at least some of the added buoyancy is removed. This causes the pipe stalk to hang with catenary curvature beneath the surface between the vessels. The catenary-curved pipe stalk hanging between the vessels is then towed to a third location for subsea installation, which may involve upending the pipe stalk before landing a lower end portion of it on the seabed.

摘要： A subsea energy storage installation comprises a pumped-storage system having pumping and hydropower generation components for, selectively, converting electricity into potential energy by expelling water from within a tank into the surrounding sea and for generating electricity from an incoming flow of water re-entering the tank under hydrostatic pressure. The tank comprises at least one elongate rigid pipeline that may be lowered to the seabed as part of a towable unit or laid on the seabed as a pipe string launched from a surface vessel.

摘要： A bending restrictor assembly (20) has a pipeline section (22), a first overlying pipe section (28) having a wall (30) overlying a portion of the pipeline section (22) at one end thereof, a second overlying pipe section (32) having a wall (34) overlying another portion of the pipeline section at an opposite end thereof, and a plurality of cylindrical members (34, 38, 38) overlying the pipeline section (22) between the first and second overlying pipe sections. The first and second overlying pipe sections extend outwardly beyond the respective ends of the pipeline section. The bending restrictor assembly achieves a permanent bend and restricts ovality of a subsea pipe.

摘要： A subsea structure comprises: an elongate articulated buoyancy string comprising a longitudinal series of buoyancy elements; and at least one elongate buoyancy holder that is fixed relative to the structure and is capable of housing the buoyancy string. The buoyancy of the structure may be altered by moving the buoyancy string along a transit path that extends along and within the buoyancy holder and through an end opening of the buoyancy holder. The buoyancy string passes through that end opening on being inserted into or withdrawn from the buoyancy holder.

摘要： A method of installing an electrically-heatable subsea flowline (16) comprises launching the flowline (16) with at least one electric power cable (28, 30) attached in piggybacked relation. After landing the flowline (16) with the piggybacked cable (28, 30) on the seabed, a free end portion of the, or each, cable (28, 30) having a length greater than the water depth is released from the flowline. This allows a free end of the, or each, cable (28,30) to be recovered to the surface to be spliced there to one or more power supply conductors. After lowering the, or each, cable (28, 30) and the, or each, connected conductor beneath the surface, the free end portion of at least one cable is reattached to the flowline (16) on the seabed in piggybacked relation. To perform the method, a subsea flowline assembly comprises subsea-releasable fastenings (66) spaced along the cable (28, 30) and the flowline (16) to attach at least an end portion of the cable (28, 30) releasably to the flowline (16).
