摘　　要：针对某薄膜型LNG船4#液货舱晃荡问题,分别选用DNV规范和基于流体体积法的软件LR.Aquarius,计算其在不同装载高度下的晃荡载荷并进行对比,发现LR.Aquarius软件在大部分装载高度下的计算结果均超过DNV规范值,据此对后续计算与校核所应参考的装载高度和计算方法提出建议。The sloshing pressure of the 4JHJ liquid cargo tank on different holding height of a membrane type LNG ship was calculated by the DNV rules and the LR.Aquarius based on the volume of fluid(VOF)method respectively.The results were analyzed comparatively,finding that the numerical values from the LR.Aquarius are larger than those from the DNV rules in most cases.Some advices were set forth about the holding height and the calculation method in the future calculation and check for sloshing problem of LNG tank.
