摘要

F-0700-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 multiconduit riser section (21) ascending from the marine floor base to a submerged buoy section (26) and a plurality of flexible flowlines (22, 70) operatively connected between the surface facility and the buoy section, and also includes a yoke beam (82, 83) which retains the flexible flowlines in a spaced linear array adjacent the buoy section; a pair of spaced arms (34) extending outwardly from the buoy section and upon which the yoke beam is mounted; a pair of retractable pins (87c) one interposed between the yoke beam and each arm spanning a slot (34a) in the arm and supporting a member (87a) projecting from the yoke beam; and means (87b) for retracting the pins to enable the projecting members to pass through the slots and permit the yoke beam to fall freely from the buoy section.
