摘要
由于LNG动力船大量装载液化天然气,其液货装载罐体积庞大且液货装载重量巨大,其由于液货罐内的液化货物对于船体运动与水动力的影响不可忽视。本文针对1艘具有C型液货罐的LNG动力船,基于势流理论,使用三维方法开展了水动力计算研究,对船体运动做计算预报,对比分析了晃荡对于船体运动响应的影响。
Due to the large amount of LNG loaded by LNG powered ships,the liquid cargo loading tank is huge in volume and weight.Therefore,the influence of liquefied cargo in the tank on hull motion and hydrodynamic power cannot be ignored.Based on the theory of potential flow,this paper studies the hydrodynamic calculation of an LNG powered ship with a type C liquid cargo tank by using three-dimensional method.The ship's motion is calculated and predicted,and the influence of swaying on the ship’s motion response is analyzed and compared.
