摘　　要：针对圆筒型浮式生产储卸油装置(FPSO)运动响应进行优化,提出带有2种新型垂荡抑制结构的圆筒型FPSO,即上扬边锋型圆筒FPSO和锯齿型圆筒FPSO。通过频域分析获得2种新型结构的幅频响应函数,初步对比判断2种新型结构运动性能的优劣,在此基础上,设计新型圆筒FPSO系泊系统并进行时域耦合分析,将计算结果与试验数据进行对比验证,在证实数值模拟准确性的同时分析新型结构的阻尼特性,得到较优的垂荡抑制结构形式。结果显示,所述的锯齿型垂荡抑制结构可有效减小纵荡和纵摇的运动幅值及幅值发生概率,降低纵荡和纵摇运动能量产生,改善整体运动性能。In order to optimize the motion response of cylindrical floating production storage and offloading(FPSO), 2 new types of cylindrical FPSO with heave suppression structures are proposed which are wrapped edge cylindrical FPSO and sawtooth cylindrical FPSO. Through frequency domain analysis, the RAOs of the 2new structures are obtained in order to preliminarily obtain the advantages and disadvantages of the 2 new structures. On this basis, for the sake of verifying the accuracy of numerical simulation and analyzing the damping characteristics of the new structure, a new cylinder FPSO mooring system is designed for time-domain coupling analysis to compare the calculation results with the experimental data. The better heave suppression structure form is obtained. The results show that: during surge and pitch motion, the sawtooth structure can effectively reduce the amplitude and probability of large amplitude;the sawtooth structures also reduce the energy of pitch and pitch motion, and improve the total motion performance.
