三模块超大型浮体锚泊系统受力分析

Mooring Tension Analysis of Very Large Floating Body Composed of Three Modules

采用锚泊系统时域耦合分析方法,基于频域计算结果建立计算模型,对三模块超大型浮体的运动和锚泊系统张力特性进行计算和分析。分析结果表明,海况的剧烈程度对浮体的运动响应产生明显的影响;在横浪状况下,浮体第二个模块两端的系泊缆承受了最大的张力,这一现象从张力有义值和最大值的统计上都得到了验证;在斜浪状况下,虽然海况依旧比较剧烈,但由于浪向的作用,整体上每根系泊缆承受的张力明显降低。

In this article,motion responses and mooring line tensions of the very large floating body composed of three-modules are calculated and analyzed based on a coupled model between floating body and mooring system in the time domain.The results show that motion responses are greatly affected by the level of the sea state.Under beam sea,mooring lines situated at both ends of the second module will sustain maximal tension,which can be validated with statistics of significant value and maximal value of tension.Under oblique wave,the mooring line tension decreases significantly,compared to that under beam wave.
