| 摘 要： | FLNG是一种新型的浮式海洋结构物,其外形与FPSO相似并配备天然气的液化装置以及LNC储罐.FLNG概念的出现使得海上边际油气的开发不再依赖于长距离的管道运输,从而节约了此类油气田的开发成本.文中基于WADAM并针对液舱晃荡与船体运动之间的相互影响进行了频域范围内的研究,在研究过程中将液舱内湿表面包含于船体外湿表面中从而形成一个统一的边界表面.通过计算得出考虑液舱晃荡与忽略液舱晃荡两种情况下的六自由度运动的RAO.对于两种情况下的计算结果进行分析研究,从而得到液舱晃荡对船体运动影响的重要规律.

| Abstract: | FLNG is a new type of floating offshore unit,which has a ship-type FPSO hull equipped with LNG storage tanks and liquefaction plants.The coupling effects and interactions between ship motion and inner-tank sloshing are investigated with the help of the code WADAM in frequency domain.A unified approach where the interior wetted surfaces of the tanks are included as an extension of the conventional defined exterior wetted surface of the body is adopted,in which all of the tank and hull wetted surfaces form a ... |
