摘　　要：分析影响超大型FPSO系泊运动响应的系泊系统设计参数,对某超大型FPSO多点系泊系统建立多种优化设计参数,并引入关键性设计约束条件,采用时域动态分析方法,将多点系泊系统的技术参数与FPSO的运动特性进行统一分析求解。以不同的系泊系统参数分析FPSO运动响应的变化趋势,采用优化分析方法得到的最优结果,分析结果表明,系泊线长度、系泊线夹角、预张紧力大小等设计参数对超大型FPSO的系泊性能有着直接影响,多参数优化设计方法能够显著提高复杂系泊系统的设计效率。The design parameters of mooring system affecting the mooring motion response of ultra-large FPSO were analyzed to optimize the design of multi-point mooring system for a type of ultra-large FPSO.By establishing a variety of optimization design parameters,introducing key design constraints,and using the time-domain dynamic analysis method,the technical parameters of multi-point mooring system and the motion characteristics of FPSO were analyzed and solved.The change trend of FPSO motion response was studied with different mooring system parameters,and the optimal results obtained by optimization analysis method were used.The results showed that the design parameters such as mooring line length,mooring line angle,and pretension force have a direct influence upon the mooring performance of ultra-large FPSOs,and the multi-parameter optimization design method can significantly improve the design efficiency of complex mooring systems.
