摘要
该文采用时域分析方法,分析了平台在系泊完好时和受力最大的锚链断裂情况下的运动响应,并参照生存状况下的操作放松未破损锚链,以减小平台系泊系统的受力。分析结果表明,平台在受力最大的锚链断裂情况下,放松其余锚链能有效减小锚链张力,该文的分析可为工程实践提供参考。
Mooring positioning system is a popular positioning system for a semi-submersible platform. The motion statistic characteristics and the tension of mooring ropes are analyzed under the condition that one mooring rope is broken as well as the mooring positioning system is complete. Furthermore, a method of loosening other mooring ropes except the broken one is introduced to improve the performance of the platform. Results show that it works effectively by loosening other mooring ropes except the broken one. The paper may be helpful to engineering practice.
