FLYTANDE PRODUKTIONSSYSTEM SAMT KAERL FOER OLJEKAELLA UNDER VATTNET. |
摘要 |
A semi-submersible vessel (24) for a floating oil production system comprises a superstructure (62) supported by legs (60) which are joined by a base (58) at their lower ends to form a rigid structure. The vessel is made from steel boxes welded together and square or rectangular in horizontal cross-section. Oil processing facilities on the vessel are connected by flexible risers (22) to the upper ends of rigid or semirigid risers (12) secured to a buoy (18) held against movement at a depth of some 50 m. The vessel is thus free to move relative to the risers (12) which are held at a level such that they are substantially unaffected by wind, wave and tidal movements. |
