摘　　要：以一双模块铰接式平台为研究对象,结合其环境监测系统及系泊力监测系统的实测数据,选取台风工况及作业工况这两个典型工况的时间段,以实测海况数据为输入,开展水动力分析并将系泊力计算结果与相应实测统计值进行对比,验证了计算模型的有效性。同时,分析了风、流载荷及系泊缆预张力对于平台系泊系统的影响,结果表明风、流载荷会显著提升系泊力水平。风、流载荷较小时,可以通过降低预张力来降低系泊力水平;而风、流载荷较大时,预张力的调整对系泊力水平的影响较小。In order to verify key technologies in the research and development of very large floating structures,a number of research institutions in China jointly deployed a double module articulated semi-submersible platform,named as Scientific Research and Demonstration Platform,and carried out long-term monitoring of the status of the platform.In this article,this platform was taken as the research object,combined with the measurement results of its environmental monitoring system and mooring force monitoring system,two typical time periods were selected,and comparative calculations were carried out.With measured sea state data used as input,hydrodynamic analysis was carried out and calculating mooring force was compared with the statistical value of measurement,so as to verify the calculation method.Influences of wind and current load and mooring pretension on the mooring system were researched.The results show that the wind load and the current load can significantly increase the extreme value of the mooring force.When the wind load and the current load are small,the mooring force can be reduced by reducing the pretension.When the wind load and the current load are large,the pretension adjustment has little effect on the mooring force level.
