摘要： A universal catenary riser support that can be designed to accommodate all riser pipe diameters typically considered for production of offshore hydrocarbons and allows the catenary riser to exit from the vessel at any azimuth angle and at a wide range of angles from the vertical. The support structure at the keel of the offshore structure is provided with a receptacle to receive a curved riser segment. The curved riser segment is adapted to be received in the receptacle. The curved riser is also adapted to receive a vertical riser section through the offshore structure. Relative motions between the catenary riser and the offshore structure are accommodated by a tapered section of riser or flexible joint attached to the curved riser section. A removable plug may be provided in the curved riser section to prevent water from entering the catenary riser during installation in the offshore structure.

摘要： The present invention provides a metal lined composite riser section for use in offshore applications featuring a traplock metal-to-composite interface to secure a plurality of structural composite overwrap layers about a metal liner assembly. Each traplock is formed with at least one annular groove or channel which has been made in the exterior surface of the metal liner assembly. The annular trap grooves may be of various geometries and may be arranged adjacent to each other to form a traplock having 2 to 8 or any number of grooves required to ensure proper adhesion between the composite overwrap layers and the metal liner assembly. A number of structural composite overwrap layers are secured about the assembly by building up alternating combinations of helical and hoop fiber windings to form a composite material. The present invention also provides a method of making composite riser sections using either a mandrel or counterweights to facilitate the composite fiber winding process.
