摘　　要：大型浮式液化天然气生产装置FLNG是一种用于深水油气田的新型开发模式。论文基于三维势流理论,建立了单点系泊FLNG船体水动力和液舱晃荡相互作用的数学模型,对载液FLNG船体运动性能分别开展了数值模拟和模型试验的系统研究。计算分析了不同压载情况下液舱晃荡对FLNG船体运动性能的影响,并将数值模拟结果与模型试验结果进行比较。研究结果表明,载液FLNG船体运动性能的数值模拟结果和模型试验结果令人满意。载液FLNG船体的横摇运动受液舱晃荡影响最大,而系泊缆索张力几乎不受液舱晃荡影响。Floating liquefied natural gas system is a new development model in deepwater oil and gas field. Based on three-dimensional potential flow theory, a mathematical model of the coupled motion response in waves is established for a single point mooting FLNG hull with liquid tanks. Global motion performance of the FLNG with liquid tanks is investigated under different load conditions by using numerical simulation and experimental methods. Numerical simulation results are presented and compared with the model test results, and satisfactory agreement is achieved. The results show that the sloshing has great impact on the roll motion of a FLNG hull with liquid tanks, but it has almost no effect on the tension of the mooting line.
