Abstract: A stabilisation system (10) for stabilising a submarine pipeline (11) supported on a seabed (13) below water level. The seabed (13) is inclined in that it incorporates a sloping section (15) extending between an upper section (16) and a lower section (17). The stabilisation system (10) comprises an upper anchoring means (21) for anchoring the pipeline (11) to the upper seabed section (16) adjacent the top end of the sloping section (15) and the other being a lower anchoring means (22) for anchoring the pipeline (11) to the lower seabed section (17) adjacent the bottom end of the sloping seabed section (15). Buoyancy means (23) are provided along the extent of the pipeline section (11a) between the two anchoring means (21, 22). The buoyancy provided by the buoyancy means (23) is sufficient to maintain the pipe section (11a) above and out of contact with the sloping seabed section (15).

Abstract: A stabilization system (10) for a section of submarine pipeline (11) comprising an end restraint (15) at each end of the section of pipeline and intermediate restraints (20) between the two end restraints (15) for limiting lateral movement of the pipeline (11) at the location of the restraints (15, 20). Each end restraint (15) is adapted to be secured to the pipeline (11) to transfer axial tension generated by lateral movement of the pipeline (11) to the seabed or ground on which the end restraint is installed. Each restraint (15, 20) comprises a pair of restraint faces (21) spaced apart to define a gap (23) through which the pipeline (11) can extend. Each restraint face (21) is configured to control curvature of the pipeline (11) during lateral movement thereof. A restraint device and a method of stabilizing a submarine pipeline is also disclosed and claimed.
