摘　　要： 结合三维势流理论和有限水深复合格林函数,计算了浅水超大型浮式生产储油系统(FPSO)水弹性响应.该方法首先实现有限水深复合格林函数及其偏导数的数值算法,将其根植于三维势流理论中,形成了用于浅水海洋浮式结构物三维水弹性分析的方法.本文对一艘浅水超大型FPSO进行了数值计算,计算结果表明,船体的振动效应对不同波浪载荷产生不同的影响. Both the three-dimensional potential theory and the composite Green funtion of restricted water depth were applied to the hydroelastic analysis of a very lager FPSO in shallow water. The numerial arithmetic of the composite Green function and its derivative of restricted water depth are carried out, which is transplanted to the three-dimensional theory to form the three-dimensional hydroelastic method for analyzing the ocean structure in shallow water. A very lager FPSO was calculated and the results show that the vibration effect has a different effect on various wave-induced loads.
