摘　　要：浮式生产储油装置(FPSO)作为海上油气开发的重要设施,确保其结构强度和完整性对于在海洋环境下开展原油集输至关重要。基于势流理论,对目标FPSO进行频域分析,研究浅水效应对船体水动力特性的影响,以及不同水深下船体的固有周期和运动幅值响应算子等水动力特性的变化趋势。结果表明,目标FPSO工作水域水深较浅时,船体垂荡、横摇和纵摇固有周期均增大;在不同水深具有相同吃水比时,除了垂荡和纵摇外,其他自由度响应均随水深吃水比的增大而减小。As important structures for offshore oil and gas development,ensuring the structural strength and integrity of FPSOs is crucial for carrying out crude oil transportation work in severe environmental conditions.Based on potential flow theory,frequency domain analysis was conducted on the target FPSO to investigate the influence of shallow water effects on the hydrodynamic characteristics of FPSO and explore the changes of the natural period and response amplitude operator in different water depths.Results show that when the FPSO operates in shallow water,the natural periods of FPSO heave,roll,and pitch all increase.When the FPSO has the same draft in different water depths,except for heave and pitch,the motions of FPSO in other degrees of freedom decrease with the increase of the ratio of water depth to draft.
