大型浮式装置艏向分析

Heading Analysis of Large LNG Floating Storage Unit

以内转塔式单点系泊27万m^3FSRU为研究对象,采用耦合时域分析方法,应用AQWA计算软件,根据其作业海域环境条件资料,计算FSRU的艏向与浪向角分布。介绍了艏向分析采用的分析方法、分析流程及相关结论。掌握单点系泊FSRU的艏向分布及FSRU与波浪入射方向夹角的分布,为后续结构强度和疲劳分析计算提供依据。

An internal turret moored 270000 m^3 FSRU was taken as the research object.By using the coupled time domain method and AQWA software,the FSRU’s heading and wave headings to the vessel was calculated according to the environmental conditions in the operating sea area.The analytical method,process and major conclusions of heading analysis were introduced.The research work can provide the basis for the subsequent analysis and calculation of structural strength and fatigue.
