摘要
介绍了一种计算系泊系统在波浪上运动响应的频域方法。采用频域格林函数法与有限差分法分别计算系泊浮体与锚泊线的运动特性,通过耦合迭代,计算了系泊系统的频域运动响应特性。最后,采用本方法计算了系泊FPSO的运动响应,通过对计算结果的分析表明本方法简单、实用,可以提供具有工程精度的锚泊性能预报。
The response function of the moored FPSO under the finite water depth is calculated by the method in which the FPSO motion is coupled with the mooring system motion in the frequency domain. Considering the limitation of the traditional calculation method in which there is too much assumption, in the paper, a new mooring-line model is adopted to calculate the mooring system. Analyzing the calculation result, the conclusion that the method in the paper is simple, practical and effective is drawn.
