组合式系泊定位下双平台联合运动模型试验研究

Experimental Study on Combined Motion Model of Two Platforms under Combined Mooring Positioning

针对两个不同功能平台联合作业的新型工作模式设计了一套新型组合式系泊系统,通过物理模型试验方法,对双平台联合作业下平台水动力特性进行分析,并与双平台独立系泊定位进行对比,结果表明该系泊系统下的双平台运动响应相对较小,锚链张力减小,联动性好,双平台联合作业适用性更佳。同时研究了该系泊系统在不同波高和波浪周期下的水动力特性,在此基础上对该系泊系统设计参数进行优化,获得了一套比独立式系泊系统经济性好、联动性好的双平台联合作业新型组合式系泊系统,为深海多平台联合作业设计提供理论支持。

A new combined mooring system is designed for the new working mode of the joint operation of two different functional platforms.Through the physical model test method,the hydrodynamic characteristics of the platform under the joint operation of two platforms are analyzed and compared with the independent mooring positioning of two platforms.The results show that the motion response of the two platforms under the mooring system is relatively small,the tension of the anchor chain is reduced,the linkage of the two platforms is good,and the applicability of the joint operation of the two platforms is better.At the same time,the hydrodynamic characteristics of the mooring system in different wave heights and periods are studied.On this basis,the design parameters of the mooring system are optimized,and a new combined mooring system with two platforms combined operation is obtained,which is better than the independent mooring system in economy and better in linkage of two platforms.It provides theoretical support for the design of deep-sea multi-platform combined operation.
