一种新型深水浮式平台及其系泊系统动力响应分析

本文以一种可支持干式采油树的新型深水浮式平台为研究对象,采用频域和时域分析方法,分析不同工况下该平台的运动响应和锚链力特性,并与试验数据相对比以验证数值方法的正确性。在此基础上,重点分析了锚链断裂和伸缩立柱长度对该平台各项性能的影响。研究表明,该新型深水浮式平台具有优越的垂荡运动性能,且伸缩立柱长度对其垂荡运动具有影响。此外,如果发生锚链断裂,将对平台水平运动及锚链力产生较大影响。

Dynamic characteristics of a novel deep water floating platform with mooring system

In the present study,a novel deep water floating platform with dry tree system is investigated.The frequency-domain and time-domain analysis methods are employed to study the motion responses and mooring forces of the platform in different sea states.The numerical results are compared with experimental results to verify the numerical method in the present study.Then,the influence of the case that a mooring line is broken and the telescopic column length on the platform performance is analyzed.Results show that the novel deep water floating platform can achieve a better heave performance.And the length of the telescopic column has an effect on the heave motion of the platform.Moreover,the performance of the platform will change significantly if a mooring line is broken.
