适应南海海况的FPSO系泊系统设计与运动响应

为保障一艘多点系泊浮式生产储卸油装置（Floating Production Storage and Offloading，FPSO）在南海恶劣海况下的安全作业，设计外转塔式系泊系统，并对船体线型进行优化分析。基于三维势流理论，应用Wadam软件建立水动力计算模型，研究不同船型方案下的FPSO频域水动力性能，最终确定优选船型。通过时域耦合动力分析方法研究FPSO系泊船体在风、浪、流作用下的运动响应特性，对比船型优化前后的运动响应和系泊缆张力结果。计算结果表明，减小艉柱倾角、增大艏柱倾角能在一定程度上降低该型FPSO在南海的纵摇和垂荡运动响应，系泊系统设计满足船级社规范要求。

Mooring System Design and Motion Response of FPSO Suitable for the South China Sea Conditions

In order to ensure the original support of a multi-point mooring Floating Production Storage and Offloading (FPSO) to achieve safe operation in the severe sea conditions of the South China Sea, an external turret mooring system is designed and the hull is optimized. Based on the three-dimensional potential flow theory, the hydrodynamic calculation model is established by Wadam software and the frequency domain hydrodynamic performance of FPSO under different ship type schemes is studied, and the preferred ship type is determined. Through the time domain coupled dynamic analysis method, the motion response of the FPSO under the action of wind, wave and current are studied, and the motion response and mooring line tension results before and after the optimization of the hull are compared. The calculation results show that reducing the stern frame angle and increasing the stempost angle can reduce the pitch and heave motion response of this type of FPSO in the South China Sea to certain extent and the mooring system meets the requirements of the classification society.
