According to the hoisting and assembling method for the GCU of the large LNG transport ship, a smoke exhaust pipe body of the GCU is divided into an upper smoke exhaust pipe section and a lower smoke exhaust pipe section, and the upper smoke exhaust pipe section and the lower smoke exhaust pipe section are connected through a sleeve. Eye plates are welded to the two ends of the upper-section smoke exhaust pipe and the two ends of the lower-section smoke exhaust pipe correspondingly, a reinforcing support is arranged in the upper-section smoke exhaust pipe, and the upper-section smoke exhaust pipe and the adjacent chimney are assembled in advance in a segmented mode. The lower section of smoke exhaust pipe and the adjacent section are pre-assembled, after pre-assembly is finished, temporary reinforcing structures are welded to the eye plate at the bottom of the upper section of smoke exhaust pipe and the eye plate at the top of the lower section of smoke exhaust pipe, and the upper section of smoke exhaust pipe and the lower section of smoke exhaust pipe are folded. And the stern building lower total assembly section is installed on the installation deck face, and after the stern building lower total assembly section is installed in place, the stern building upper total assembly section and the stern building lower total assembly section are folded. By means of the two-section type design, the limitation of the transportation capacity of vehicles in a plant is avoided, the transportation difficulty in the plant is reduced, the two smoke exhaust pipe sections are pre-assembled with the adjacent sections correspondingly, the total assembly hoisting frequency is reduced, and the production efficiency is improved.
一种大型LNG运输船气体燃烧装置GCU的吊运组装方法,GCU排烟管主体分为上段排烟管和下段排烟管,两段之间通过套管连接。上段排烟管和下段排烟管的两端均焊接有眼板,上段排烟管内部设置有加强支撑,上段排烟管与相邻的烟囱分段预先组装。下段排烟管与相邻分段预先组装,预先组装结束后,在上段排烟管底部的眼板处、下段排烟管顶部的眼板处焊接临时加强结构,将上段排烟管与下段排烟管合拢。在安装甲板面安装艉楼下部总组段,艉楼下部总组段安装就位后,将艉楼上部总组段和艉楼下部总组段合拢。本发明通过两段式设计,规避了厂内车辆运输能力的限制,降低厂内运输难度,两段排烟管段分别与邻接分段预组,减少总组吊运次数,提高生产效率。
