| 摘 要： | 为研究液舱内液货自由面水动力效应对船体波浪载荷及船体运动的影响,基于一艘15万吨FPSO,选取液货舱原始布置形式下两种典型装载工况以及一组具有不同长度中部半载液舱的FPSO液舱分布模型,分别采用准静态方法和全动态方法对船体波浪载荷及运动进行计算。结果表明,使用准静态方法进行波浪载荷预报具有工程可靠性,中部半载液舱长度对船体波浪载荷及运动有一定影响。

| Abstract: | A 150 000 t FPSO is selected to investigate the dynamic effect of free surfaces in cargo tanks on wave loads and motions of ship hull. It carries out the calculations of hull wave loads and motions by the quasi-static method and the whole dynamic method, respectively, under the two typical loading conditions with the original arrangement of liquid cargo tanks and a set of distribution models of liquid cargo tanks for FPSO with the different lengths of half iflled tanks at the middle of the hull. The results show that the quasi-static method is reliable for the wave loads prediction, and the length of half iflled tanks at the middle of the hull has an impact on the hull wave loads and motions. |
