针对一个具有非对称下浮体结构的新型半潜式起重平台,基于三维势流理论,采用水动力计算软件Aqwa,根据系泊系统设计标准,对该平台的悬链式系泊系统进行布置并进行3 h时域系泊模拟。考虑3种不同的风浪流海况,研究此平台的系泊系统特性。研究发现8根系泊缆方案较12根系泊缆方案更为经济且能满足性能要求,最后针对8根系泊缆方案选取了5种悬链松弛度,对比找出最佳松弛度,发现最佳松弛度为7.5。
For a new semi-submersible lifting platform with an asymmetric lower floating body structure. Based on the three-dimensional potential flow theory. According to the mooring system design standards, the hydrodynamic software Aqwa is used to simulate the layout of the catenary-type mooring system of the asymmetric semi-submersible lifting platform. A 3-hour time domain mooring simulation has been conducted to study the mooring system characteristics of the platform under three different wind-wave-current conditions. It is found that the 8-mooring-line scheme is more economical than the 12-mooring-line scheme and can satisfy the performance requirement. Finally, based on the 8-mooring-line scheme, 5 kinds of catenary slack are selected and compared to find the best slack.The optimal relaxation was found to be 7.5.
