波浪载荷对FLNG运动响应的影响规律研究

摘要

In order to analyze the influence pattern of wave load on FLNG motion response,a FLNG model was built,and the time-varying motion response and the amplitude response of three-dimensional motion of FLNG under different wave load were obtained using hydrodynamic numerical simulation method.The motion response pattern was also studied.The results showed that the motion response of FLNG increase with the increase of significant wave height;with the same significant wave height,the direction of motion response which plays the major role depend on the course angle of FLNG.The results can provide beneficial reference for process design,operation safety and sloshing platform experimental design.%为分析波浪载荷对FLNG运动响应的影响规律,建立了FLNG的模型,基于水动力学数值模拟的方法,得到了FLNG在不同的波浪载荷作用下随时间变化的运动响应及各自由度的幅值响应,并对其规律进行了分析研究.结果表明,FLNG的运动响应会随着有义波高的变大随之升高;在相同的有义波高的情况下,起主要作用的运动响应方向取决于FLNG的航向角.研究结果可以为FLNG的相关工艺设计、运行安全性、及海况晃动平台的实验设计提供有益的参考.
