规则波中FPSO的水动力性能分析

摘要

A FPSO is studied using the hydrodynamic analysis software AQWA to study the dynamics of FPSO under different drafts and different incident wave angle.As the draft increases,the added mass and radiation damping coefficient incrcase.The first order wave force is sensitive to the change of frequency,all of which have 3 to 4 peaks.With the increase of incident wave frequency,the wave force is obviously reduced.%利用水动力软件AQWA研究FPSO在不同装载状况以及不同入射角下的水动力性能.结果表明:附加质量、辐射阻尼系数随着FPSO吃水的增加而显著增大;一阶波浪力对频率变化比较敏感,均有3～4个峰值;随入射波频率的增大,浮体受到的波浪力明显减小.
