摘　　要：应用势流理论,结合油船的水动力模型,计算分析了在风、浪、流作用下油船系泊平台的运动响应、系缆力和护舷碰撞力。考虑了系泊力和护舷受力的非线性,波浪为不规则波,讨论了不同环境方向和不同波高对系缆力和碰撞力的影响。以某一平台为例,计算得到了平台外输作业的限制工况。Based on the theory of potential flow, a hydrodynamic model of vessel was built to calculate the motion response, mooring forces and collision forces of a tanker moored to a platform under the combined action of wind, tide and waves. Considering the non-liner load-deformation functions of the mooring lines and fenders and irregular waves, the effect of the angles and wave heights on the mooring forces and impact forces were analyzed. A platform was taken as example to determine the limited operation condition for offloading.

关 键 词：外输作业 系缆力 非线性 护舷碰撞力
