| 摘 要： | 作为浮式结构最常采用的两种系泊方式,悬链式系泊和张紧式系泊皆存在不足。本文提出了一种新型系泊系统,并以一深水FPSO为例,采用完全时域耦合分析方法,对不同工作水深情况下的浮体及新型系泊系统的运动性能进行了数值模拟,并将该新型系泊系统的仿真结果与传统的张紧式系泊系统进行了比较,分析了新型系泊系统在浮体运动性能、缆索张力等方面的改善,同时探讨了该新型系泊系统的最佳工作水深。

| Abstract: | Catenary mooring system and taut mooring system are two widespread mooring systems which are applied for the floating structures.However,both of them have their inherent drawbacks.The aim is to develop a new mooring system which will overcome these shortcomings.To validate the efficiency of the new system,the new mooring system applied to a deepwater FPSO was selected as the numerical example.The motion performance of the FPSO platform with the new mooring system under different water depth was simulated employing full time domain coupled analysis method.The numerical simulation results show that the new mooring system yields very good motion performance compared to the taut mooring system.Finally the optimal water depth of the new mooring system where the floating offshore platforms can obtain the best performance was discussed. |
