摘要： A riser disconnect and support mechanism for flexible risers and umbilicals on an offshore structure with low under keel clearance. A main body portion includes an inverted and truncated conical or convex section substantially at the center of the main body portion. The main body portion and conical section receive risers therethrough by means of a plurality of conduits through the main body portion and conical section. A plurality of projections extend radially outward from the main body portion. A plurality of arch-shaped riser supports are provided on each projection to support risers and/or umbilical lines and control their bending radii. The projections extend out from the main body portion at a distance that allows the portions of the risers below the main body portion to hang at an angle and bend radius in accordance with the design tolerances of the risers to prevent buckling or damage due to excessive bending while keeping the risers from contacting the sea floor.

摘要： A subsea catenary riser system (40) comprises a conduit (42) extending between a surface vessel (44) and a subsea support (46) in a catenary form. A load arrangement (48) is connected between a subsea anchor (54) and the conduit (42) at a region of connection (50) which is intermediate the vessel (44) and the subsea support (46) to apply a force on the conduit (42). The conduit (42) is configured such that the applied force generates axial tension in the conduit (42) between the region of connection (50) and the vessel (44), and between the region of connection (50) and the subsea support (46).

摘要： A floating vessel configured to support at least one of: drilling of wells, workover of wells, production, and storage of hydrocarbons, and personnel accommodation, having a hull. The hull has a bottom surface, a top deck surface, and at least two connected sections engaging between the bottom surface and the top deck surface. The at least two connected sections are joined in a series and symmetrical about a vertical axis. The connected sections extend downwardly from the top deck surface toward the bottom surface. The connected sections can have an upper cylindrical portion, a neck section, and a lower conical section. At least one fin is secured to the hull and the lower conical section provides added mass improved hydrodynamic performance through linear and quadratic damping to the hull.

摘要： A clamp for a flexible pipe is provided that provide a load bearing flange on the flexible pipe permitting buoyancy jackets to be joined thereto. The clamp has a longitudinal axis arranged to extend along the length of the flexible pipe and a radial axis being perpendicular to the longitudinal axis. The clamp includes: a plurality of separate clamp elements being supported together in a radial array extending at least partially around the longitudinal axis; engagement means located between neighboring clamp elements to movably interconnect the clamp elements; and a strap being adapted to surround the clamp elements, in use for exerting a compressive force thereon. Also provided is a clamp element for use in the aforementioned clamp.

摘要： A subsea riser system with a gas-lift facility has a production riser having a riser conduit and at least one lift gas injection port communicating with the riser conduit. An umbilical is arranged to supply lift gas to the lift gas injection port. A heating unit is positioned to act on a downstream end region of the umbilical adjacent to the lift gas injection port. A method of providing lift gas to a subsea riser system includes the steps of conveying lift gas toward a production riser and, before injecting the lift gas into the production riser, heating the lift gas locally adjacent to the production riser.
