联合考虑FPSO与穿梭油船之间的水动力耦合效应，以及船体与软刚臂系泊系统、连接缆、旁靠靠球之间的相互作用，基于三维势流理论对软刚臂系泊FPSO旁靠外输作业进行多浮体水动力响应时域分析。针对耦合外输系统中的连接缆，分析缆绳刚度、绳长和布置形式的改变对缆绳安全系数的影响。通过不同环境组合下两种典型装载工况结果分析表明：加粗连接缆、交叉布缆、以及调整连接缆长度使得连接缆受力均衡可以有效地提高系统作业安全性。

Based on 3D potential flow theory , hydrodynamic response analysis was carried out on the multi floating bodies system composed of FPSO moored with yoke and shuttle tanker .It considered hydrodynamic interaction between FPSO and shuttle tanker, interaction between the hull and yoke mooring systems , hawsers, fenders.The influence of hawsers parameters on system safety was studied in respects of hawser stiffness , length and arrangement .Analysis rsults of two typical loading conditions in dif-ferent environment conditions showed that a better safety performance can be achieved by means of enlarging the number and stiff -ness of hawsers , changing the length and arrangement of hawsers .
