MARINE COMPLIANT RISER SYSTEM

摘要

F-0633-L MARINE COMPLIANT RISER SYSTEM A marine compliant riser system for connecting a marine floor base (24) to a marine surface facility (22a) includes a riser section (21) ascending to a submerged buoy section (26) and a flexible section (22) connecting the buoy section to the surface facility. The flexible section comprises flexible flowlines (70) in a catenary path maintained in a linearly spaced parallel array over most of their length by spreader beams (75) having apertures (77) through which the flowlines are movable longitudinally. The spreader beams are connected in sequence and suspended from the surface facility and buoy section by cables (80). The flexible flowlines are connected to the surface facility in a radially spaced array and depend from the buoy section and surface facility at substantially vertical catenary departure angles.
