摘要
用短峰波理论并采用谱分析法,对在南海100年重现期极端环境条件下转塔式单点系泊的浮式生产储油装置(FPSO)的耐波性进行了分析。与长峰波理论计算结果相比,短峰波理论计算结果具有以下特点:①FPSO横摇运动幅值和纵摇运动幅值对波向角的变化不太敏感,其最大值与最小值之间的差值较小;②在迎浪状态下FPSO的横摇运动幅值不为0,而且会产生较大的横摇运动响应;③在横浪状态下FPSO也会产生较大的纵摇运动响应。短峰波理论的运动响应计算结果打破了PFSO在迎浪时模摇运动为0,在横浪时纵摇运动为0的传统观念。南海FPSO设计运动参数选择以短峰波压载状态下的计算结果为依据。
The sea keeping ability has been analyzed on turret single buoy mooring floating production storage unit(FPSO) by short-crested wave theory and spectral analysis method for 100 years return period extreme environment in the South China Sea.Comparing to the results of long-crested wave theory,the results of short-crested wave theory are characterized by ① the amplitude values of rolling movement and pitching movement are not sensitive to the variation of wave direction angle,with smaller difference between their maximal value and minimum value;② under opposing wave,the amplitude value of rolling movement of FPSO was not zero,with larger rolling movement behavior;③ under cross wave,there would be larger pitching movement of FPSO.The results calculated by short-crested wave theory break the traditional concept that the rolling of FPSO is zero under opposing wave and the pitching of FPSO is zero under cross wave.The design movement parameters of Nanhai FPSO were selected according to the results of short-crested wave theory in ballasted condition.
