八角形浮式生产储油装置关键技术与应用探索

Research on octagon FPSO key technology and its application in shallow waters

针对渤海边际油田开发的需要,提出了八角形浮式生产储油装置(FPSO)的概念,探讨了将八角形FPSO用于浅水海域小型油田或边际油田开发的"蜜蜂式"开发模式,并对八角形FPSO总体布置、与井口平台间的柔性连接、原油外输方式、浅水海域多点系泊系统、环形舭龙骨等关键技术进行了研究。这些初步成果可为今后研究开发各种全新概念的FPSO提供借鉴,也将积极推动我国浅水海域小型油田或边际油田的开发。

For fulfilling the demands of developing marginal fields in Bohai sea, a new Floating Production Storage and Offloading （FPSO） system concept—— octagon FPSO is proposed. In this article, the ＂bee mode＂ development of small or marginal fields in shallow waters using octagon FPSO is discussed; key technologies are researched on the general arrangement of octagon FPSO, the flexible connection technology between octagon FPSO and WHP, oil offloading, multi-points mooring system in shallow waters and the ring bilge keel. The primary research results can provide reference for research and development of new concept FPSO henceforth, and can promote actively the development of small or marginal fields in shallow waters.
