摘　　要：本文简要描述了深远海油气资源开发保障平台的工程概况及其所处的海洋环境,介绍了其系泊系统类型及基于三维水弹性的系泊力计算方法和数值模型。通过在流体恢复力矩阵中增加计及系泊力的耦合动力学分析方法,采用COMPASS-THAFTS软件对深远海油气资源开发保障平台在规则波作用下的动力特性进行频域分析,比较了不同航速下的运动响应和弹性响应。研究结果表明,在服务航速顶浪航行情况下较容易发生波激振动现象,可为深远海油气资源开发保障平台的结构设计及性能评估提供技术基础。The engineering overview and the marine environment of the deep-distance offshore oil and gas resource development support platforms and their mooring system types were described briefly.Based on three-dimensional hydroelasticity,the calculation method of mooring force and numerical model were introduced.By using a coupled dynamic analysis method taking into account the mooring force in the fluid restoring force matrix,the COMPASS-THAFTS software was used to analyze the dynamic characteristics of the deep ocean oil and gas resource development support platform under regular waves in the frequency domain.Furthermore,the motion response and elastic response at different speeds were analyzed.It is concluded that the wave-induced vibration is more likely to occur when sailing in the head sea at service speed,which provides a technical basis for the structural design and performance evaluation of the deep ocean oil and gas resource development support platform.
