摘要
以工作水深1200m、8缆系泊的半潜式海洋平台为对象,研究其系统定位方法,提出了在风、浪、流联合作用下通过改变泊缆长度来实现平台定位的研究方法。建立反映半潜式海洋平台锚泊系统动力响应的多目标优化模型,通过求解得到船体目标位移与最优系泊缆长度,借助多学科软件iSIGHT,通过开发程序接口,调用水动力分析软件ANSYS/AQWA求解器求解,实现了半潜式平台锚泊系统的结构动力响应优化设计。
Taking the semi-submersible platform that working in depth 1200m with 8 mooring platform as example to analyze the system positioning method,changed the mooring line length in the mooring system. The multiple objective optimization models to react the semi-submersible dynamic response system platform was established, this helps to get the ship target displacement and optimal mooring line length. With the help of interdisciplinary software iSIGHT and the optimization design of structural dynamic mooring system through the development of program interface, then called hydrodynamic analysis software ANSYS/AQWA solver solutions to realize semi-submersible platform response.
