摘　　要：介绍了FPSO性能分析的一般流程和波浪预报方法，并利用SESAM程序分析和预报了渤海某浅水型FPSO运动固有周期和遭遇百年一遇海况的最大剪力、最大弯矩的分布情况，该计算结果可作为FPSO船体型线优化、船体强度校核和系泊系统设计分析的参考。FPSO is a floating system fixed at certain sea area by mooring lines during its operational period. Because of its excellent motion performance, earnings ratio and easy transport, more and more FPSOs have been built in China in recent years. Hydrodynamic performance and motion analysis,as well as basic methods for waves prediction are introduced in this paper. Then natural periods are given with different motion freedom. Also maximum shear and moment distribution along the length are predicted at the return period of 100 years. These results can be used for hull molded lines optimization, global strength check and mooring coupled analysis.
