The invention discloses a bulkhead transition structure for a thin-film containment system of an LNG (Liquefied Natural Gas) ship and a mounting method of the bulkhead transition structure. A layer of transition bulkhead capable of separating two adjacent cabins is arranged between the two adjacent cabins, transition assemblies are respectively arranged at two end parts of the transition bulkhead, and the transition assemblies are fixed on a cargo hold outer plate of a liquid cargo hold; the insulation structures of the two adjacent cabins are fixedly welded to the two sides of the transition assembly to form a bulkhead transition structure, and the bulkhead transition structure is used for replacing a traditional isolation void between the two liquid cargo tanks, so that a traditional isolation void and a pump tower structure are omitted, the space is greatly saved, and the tank capacity is improved; the loading volume of the cargo hold is increased, the construction efficiency is improved, and the production cost is reduced.

本发明公开了一种LNG船薄膜型围护系统舱壁过渡结构及其安装方法，本发明通过在相邻两舱室之间设置一层可以将相邻两舱室隔开的过渡舱壁，在过渡舱壁两端部分别设置过渡组件，将过渡组件固定在液货舱的货舱外板上，并将相邻两舱室的绝缘结构与过渡组件的两侧焊接固定，形成一个舱壁过渡结构，利用该舱壁过渡结构来替代传统的布置在两个液货舱之间的隔离空舱，从而取消了传统隔离空舱和泵塔结构，大大节省了空间，提高了舱容，提升了货舱装载容积，提高了建造效率，降低了生产成本。
