利用水动力分析软件AQWA研究了内转塔式单点系泊参数对海上浮式生产储油船FPSO（ floating production，stor-age and affcoading system ）系统动力效应的影响特性，定量分析了内转塔位置、系泊缆材料分布、系泊缆预张力、系泊缆数量、系泊缆布置形式等参数对FPSO系统动力效应的影响，对每个系泊参数采取多个特征量进行比较分析，计算结果表明：转塔位置距船艏柱25％Lpp时风标效应及定位效果最好，多成分系泊缆材料分布采取下端钢链9％、聚酯缆90％、上端钢链1％时，系泊缆数量取9根且为3组×3根/组布置时定位效果最好，缆绳受力最小。以FPSO水平偏移量与系泊缆的安全系数为目标，提出了一套系泊系统的优选方案，计算结果表明系泊性能优良，与初步设计方案相比有了显著地提高。文中的计算及分析结果对内转塔式FPSO系泊系统的设计具有一定指导意义。%In this paper , the influence of BTM ( Buoyant Turret Mooring ) system parameters on dynamic re-sponse of FPSO system was analyzed by software AQWA .The influence of parameters , such as turret location , materials distribution , pre-tension of mooring lines , the number of mooring lines , layout of mooring lines etc ., on dynamic response of FPSO system was analyzed quantitatively .Several characteristics were comparatively ana-lyzed for each mooring parameter .The results showed that when turret was located at 25%Lpp, the system had best weather vane and positioning effect .If 9%chain,90% polyester,1%chain was taken as multi-component mooring line, and mooring lines were arranged as 3groups ×3/group, the system would have positioning effect and the lines would have minimum force .An optimized proposal of mooring system was suggested by comprehen-sively considering the horizontal displacement of FPSO and the safety factor of mooring lines .The result showed that the optimized mooring system would have excellent performance , and it was significantly improved compared with the initial program .The conclusion will be helpful for the design of the BTM .
