中文摘要：

系泊系统是FPSO设备的重要组成部分，应用三维势流理论、时域非线性有限元法模拟系泊缆索动力特性，以挪威船级社（DNV）的SESAM程序作为主要工具，对单点分组系泊形式下的FPSO运动响应及系泊力问题进行研究。给出了FPSO六个自由度的运动情况和导缆孔处张力结果，得出作用在FPSO上的波浪漂移力与一阶波浪激振力在同一个数量级都比较大。

英文摘要：

Mooring system is an important part of FPSO. Using 3D potential fluid theory,, dynamic characteristics of mooring cables simulated by time-domain non-linear finite element method, the SESAM program of DNV is taken as the main tool to analyze the motion response and mooring tension of FPSO which moored by the single point mooring equipment. It is given the movement situation of the 6D motions of FPSO and the result of mooring tension of the fair-lead It is educed that both the wave drift force and the wave excitation lstOrd and are strong at the same order of magnitude.
