基于浮体水动力计算直接时域法和系泊缆静力分析法建立组合系泊系统在外载荷输入下的时域运动方程,采用添加锚链配重块的方式提高主系泊缆的系泊能力,并将主系泊缆作为系统主要位姿控制模块进行深入研究。研究结果表明：采用组合系泊的方式使平台边缘受水平牵引力平均降低36.7%;组合系泊系统提供的水平恢复力相比于四点系泊系统平均增加27%,系泊张力平均降低34%,组合系泊在满足浮动平台系泊条件的同时大幅降低对平台随浪波动特征的影响。
Abstract
Based on the direct time domain method of hydrodynamic calculation of floating body and the static analysis method of mooring line, the time domain motion equation of combined mooring system under external load input is established, and the mooring capacity of main mooring line is improved by adding anchor chain counterweight, and the main mooring line is used as the main position and attitude control module of the system for in-depth research. The results show that the horizontal traction on the platform edge is reduced by 36.7% on average by using the combined mooring method. Compared with the four-point mooring system, the horizontal restoring force provided by the combined mooring system is increased by 27% on average, and the mooring tension is decreased by 34% on average. The combined mooring system not only meets the mooring conditions of the floating platform, but also greatly reduces the impact on the wave fluctuation characteristics of the platform.
