摘要： Transferring liquid hydrogen between an onshore source and an offshore terminal without a jetty using subsea concentric pipe-in-pipe lines extending between source and terminal. A loading pipe-in-pipe line carries liquid hydrogen, while a return pipe-in-pipe line carries displaced vapour from the terminal back to the source. Compressor located at terminal compresses returned vapour, allowing the loading and return lines form a recirculating loop to maintain a cryogenic temperature of the liquid hydrogen. Annular volumes between the inner and outer pipes of the pipe-in-pipe lines have insulation and a partial vacuum. Outer pipes have three-layer polyethylene anti-corrosion coating, cathodic protection in the form of sacrificial anodes, and a fibre optic leak detection system to identify inner pipe leak locations.

摘要： The pile plug (1) has independent buoyancy, high displacement and a rigid structure of the skeleton (2) and a flexible sheath (3) at least on the side surface of the plug body, while the flexible sheath constitutes an airtight container equipped with pneumatic valves (4). The sheathing material (3) of the plug (1) can be made of a material with a high friction coefficient in relation to the pile material selected from the group: natural rubber, synthetic rubber, polyurethane. Inside the cap (1) there is a pile venting pipe (14) closed with a pile venting valve (15), which connects the space inside the pile with the surroundings. Preferably, the cap (1) has a ballast load (16) internally for positioning the plug with respect to the pile and for balancing the cap horizontally and also preventing unfavourable rotation of the pile.

摘要： A structure such as a pipeline bundle is pulled into or through shallow water, for example when launching the structure, by applying a tensile pulling force to the structure through rigging that extends to the structure from a winch of a first vessel. The pulling force is at least partially reacted through a pennant line that extends from the first vessel to a second vessel and that hangs between the first and second vessels to engage the seabed soil frictionally. The vessels may also self-propel to contribute their thrust to the pulling force. The pennant line includes a clump weight such as a bundle of chains that can be repositioned easily for additional pulls by being lifted between the vessels before being lowered to the seabed at a new location.

摘要： Disclosed is conduit anchor, an offshore system comprising a conduit anchor and a method of deployment. The conduit anchor includes a base section adapted for attachment to a conduit, and a conduit guide extending from the base section. In use a dynamic conduit extends along a dynamic conduit pathway range defined by the anchor, via the conduit guide. The conduit guide comprises a convex bend protecting surface region oriented towards the dynamic conduit pathway range which in use protects against over bending of the dynamic conduit.

摘要： A method of connecting a conduit (10) to a subsea structure (20) is provided. In the disclosed method, a tensioning member (16) is provided on the conduit and attached to the conduit at two locations proximate a first end (14) of the conduit. The tensioning member is used to maintain a curvature formed in the conduit between the two locations e.g. by deflecting a portion of the conduit. A first end of the conduit is engaged with a guide assembly (30) provided adjacent to the subsea structure, and tension in the tensioning member is released to adjust the axial position of the first end of the conduit to enable direct connection between the conduit and the subsea structure. A method of disconnecting a conduit from a subsea structure, and a system for connecting a conduit to a subsea structure are also provided.

摘要： A method of launching an elongate subsea structure such as a pipeline bundle unit into water comprises providing buoyant support to the structure by displacing water with a hollow buoyancy unit that applies buoyant upthrust to the structure. By lowering the buoyancy unit in the water to bring a permanently open aperture of the buoyancy unit beneath a surface level of the water, the buoyancy unit is flooded with water through the or each permanently open aperture to reduce the buoyant upthrust applied to the structure.

摘要： The present disclosure relates to apparatus and methods for introducing residual curvature to sections of pipeline during S-lay, where the residual curvature is introduced on the lay barge (100) before the selected section reaches the stinger (120). By bending a pipeline section before the pipeline section reaches the stinger, the pipeline can be monitored during bending, by the bending apparatus (104) to ensure that the proper curvature is induced. Additionally, introducing the curvature before the stinger allows residual curvature methods to be used on S-lay vessels where the stinger or stinger rollers are not adjustable while the pipeline is in place.
