针对南海中等水深边际油田开发需求,结合国内外相似工程案例,通过方案比选,确定多边形FPSO浮体形式.以南海海况和边际油田油藏为基础,进行主尺度、舱容、总布置、稳性、运动性能、多点系泊、海管海缆以及2点外输设计.结果表明,多边形FPSO能够适用于南海的海况,满足生产的功能需求和规范要求,是值得深入研究的工程方案.%Considering the similar engineering cases, the floating body of polygonous FPSO was selected for the development of the marginal oil field in medium water depth area in south China sea.Based on the sea state and oil reservoir, design of the FPSO were completed, including main dimension, tank capacity, general arrangement, stability, motion performance, spread mooring system, sea tube, cable and two-point offloading.It was shown that the polygonous FPSO is suitable for the sea state of south China sea.The designed FPSO can meet with functional requirement and rules.
