The invention discloses an LNG ship transverse bulkhead spiral duct middle assembly stage construction and installation method. The method comprises the following steps that a transverse bulkhead is divided into a transverse bulkhead front wall middle assembly and a transverse bulkhead rear wall middle assembly in a segmented mode; constructing a transverse bulkhead rear wall middle assembly; constructing a transverse bulkhead front wall middle assembly: normally mounting a transverse bulkhead spiral duct on the transverse bulkhead front wall middle assembly; the transverse bulkhead front wall middle assemblage is overturned and hoisted on the transverse bulkhead rear wall middle assemblage to form a transverse bulkhead segmented large assemblage; bulk parts are installed on the large transverse bulkhead section assemblage to form transverse bulkhead sections. According to the method, the installation procedure of the transverse bulkhead spiral duct is moved forward to the middle assembly stage of the transverse bulkhead sections, normal installation of the transverse bulkhead spiral duct can be completed on the section jig frame, a truck crane does not need to be used for auxiliary installation, the fitting-out period of the section stages is not occupied any more, and the installation efficiency is improved. The circulation efficiency of the sections is improved through lower construction risks and higher outfitting efficiency, and the overall construction period of the LNG ship is shortened.

    本发明公开了一种LNG船横隔舱螺旋风管中组立阶段建造安装方法包括以下步骤:将横隔舱分段划分为横隔舱前壁中组立和横隔舱后壁中组立;建造横隔舱后壁中组立;建造横隔舱前壁中组立:在横隔舱前壁中组立上正态安装横隔舱螺旋风管;将横隔舱前壁中组立翻身吊装在横隔舱后壁中组立上,形成横隔舱分段大组立;在横隔舱分段大组立上安装散装件,形成横隔舱分段。本发明将横隔舱螺旋风管的安装工序前移至横隔舱分段的中组立阶段,在分段胎架上即可完成横隔舱螺旋风管的正态安装,无需使用汽车吊辅助安装,不再占用分段阶段的舾装周期,以更低的施工风险和更高的舾装效率来提升分段的流转效率,缩短LNG船整体建造周期。
