中文摘要：

应用三维线性势流理论和Ir J A Pinks时的近场分析方法，对超大型浮式生产储油系统（32万吨FPSO）的二阶波浪定常力进行了数值仿真分析，研究浅水情况下，不同水深对FPSO受到二阶波浪定常力的影响，对浅水油田中FPSO的设计应用有一定的实用意义。

英文摘要：

In this paper, a 320 kDWT FPSO is investigated using numerical calculations on second order mean wave drift force with different water depths in shallow water based on three-dimensional theory and Pinkster＇ s near field analysis approach. The effects of different water depths on the second order mean wave response of FPSO are given. The research result is expected to be used in optimizing the design of the FPSO in the oil fields with shallow water.
