The invention discloses a fixing structure of an LNG tank in a ship enclosure bulkhead structure and a mounting method of the LNG tank, the fixing structure is composed of a fixing structure with a sliding base and a fixing structure of a fixing base, and the fixing structure with the sliding base comprises the sliding base, low-temperature lubricating grease, a stainless steel plate and a fastening device; the fixing structure with the fixing base comprises the fixing base, a thrust device, low-temperature lubricating grease and a fastening device. The installation method comprises the steps that before the LNG tank is installed, pressure and vacuum inspection is conducted on the LNG tank, meanwhile, the flatness and perpendicularity of the upper surface of the base are detected to meet design requirements, the size of a saddle of the LNG tank and the center distance of bolt holes are checked again, low-temperature lubricating grease is poured after the LNG tank is positioned, hardness testing is conducted, a torque wrench is used for fastening the fastening device according to the torque required by the design, and the LNG tank is installed. And finally, the mounting operation is finished.

    本发明公开了一种船舶围壁结构内LNG罐的固定结构及LNG罐的安装方法,由具有滑动基座的固定结构和固定基座的固定结构构成,具有滑动基座的固定结构包括滑动基座、低温润滑脂、不锈钢板和紧固装置;具有固定基座的固定结构包括固定基座、止推装置、低温润滑脂和紧固装置。安装方法为:LNG罐安装前,对LNG罐进行压力及真空检查,同时检测基座上表面平面度、垂直度符合设计要求,复核LNG罐鞍座尺寸及螺栓孔中心距,LNG罐定位后浇注低温润滑脂,并进行硬度测试,利用力矩扳手对紧固装置按照设计要求力矩进行紧固,并最终完成安装作业。
