摘要
基于三维势流理论和悬链线理论,系统地对南海百年一遇海况时不同载液率下浮式液化天然气生产装置的运动性能进行研究,并与模型试验结果进行验证分析。研究结果表明,南海浮式液化天然气生产装置运动性能的数值预报和试验结果具有较好一致性。不同载液率装载工况对浮式液化天然气生产装置横摇运动性能的影响较大,而系泊缆索张力几乎不受舱内液体晃荡影响。该研究结果可为浮式液化天然气生产装置的设计提供理论依据。
Based on the three-dimensional potential flow theory and the catenary theory, the motion performance of FLNG system are investigated with different loading rate of liquid conditions un- der sea states of the hundred years in the South China Sea. Then the numerical prediction results are presented and compared with the model test results. Satisfactory agreement is achieved. The results show that the different loading rate of liquid has great impact on the roll motion of FLNG system. The sloshing effect has almost no effect on the tension of the mooring line. The results of this study can provide theoretical basis and technical support for the design of FLNG system.
