| 摘 要： | 通过在系泊缆中设置浮子可以改善系泊系统性能,降低平台运动响应。建立浮子式系泊系统的数值计算模型,验证浮子式系泊系统数值计算方法,详细分析浮子设计参数(设置位置和净浮力大小)变化对系泊缆张力特性与平台运动的影响规律,并根据得到的规律选择了优化的浮子系泊系统方案。最后对优化方案进行评估,表明优化方案可以显著降低系泊中的平台水平运动,尤其是低频运动,同时系泊缆张力变化不大,仍满足安全要求。研究结果可为今后浮子式系泊系统设计提供参考。

| Abstract: | Inserting buoys to the mooring system can improve the performance of mooring system as well as decrease the platform motion. In this paper, the model of mooring system with buoys is introduced, the numerical simulation method of mooring system with buoys is validated, and the design parameters of buoys (location and net buoyancy ) are studied to see their influence on the mooring line tension as well as the platform motion. An optimized plan of mooring system with buoys is selected according to the conclusions made. At last the optimized plan is analyzed, and turns out to be effective in decreasing the offset, especially the low frequency part of platform, while the mooring tension does not increase obviously, still within the safety requirement. The results of this study could offer reference in designing of the mooring system with buoys. |
