摘要
FPSO型采油平台是一种极为重要的深海石油勘探、生产设备。为了保证其在生产和使用中的绝对安全,对其设计和建造所采用的波浪外力荷载和运动响应幅值有很高的要求。本研究采用有限水深格林函数和考虑几何对称性的高阶边界元的方法,对一种已投入实际生产的FPSO进行了全方向波浪力和运动响应计算分析。同时通过在边界积分方程中增加辅助内域常数势的方法去除了不规则波浪频率,获得了满意的外荷载设计参数。
The FPSO type platform is a very important ocean equipment for oil exploration and production, especially in deep sea. The designing requirement of wave exciting force and motion response should make this kind offshore structure absolutely safe within the running cycle of its production.In this paper,the shallow water Green function and higher order boundary element method are utilized to investigate the wave exciting force and motion response of one kind FPSO currently in use under different wave incident. A novel method by applying constant potential in inner field of body boundary can remove ＇irregular wave frequency＇ directly and obtain wave loads satisfactorily.
