摘　　要：在波浪等外载荷的影响下,FLNG液舱内的LNG(液化天然气)在运输过程中会产生剧烈的晃荡作用,对液舱舱壁产生冲击,这对船体及液舱结构的设计以及船舶拖航的稳定性提出了挑战。液舱晃荡与船舶运动的耦合作用是当前的研究热点,研究过程中模型试验的方法得到越来越广泛的应用。基于推板造波理论,设计并制作出一套单向推板造波系统,并按照1/300的缩尺比设计制作出FLNG及液舱模型,进行了模型试验。通过试验研究了载液率对液舱晃荡剧烈程度的影响效果,对匀速拖航过程中影响拖缆张力的部分因素进行了对比研究。研究结果可为后续相关研究工作提供基础。Under the influence of the external loads such as waves,LNG （liquefied natural gas） in tanks may result in a dramatic sloshing during transportation,which has an impact on the tank bulkhead;and provides huge challenges to the design of the hull structure and ship towing. Coupling of tank sloshing and motion of the ship is a research hotspot,and model tests have been more widely used. This paper designed a piston- type wave maker and FLNG models in the scale of 1/300. The tests studied the intensity of sloshing under different liquid rates,and carried on a comparative study on various factors which could have influences on towline tension in the process of uniform towing. The experimental results can provide reference for engineering practice.
