The invention discloses a cabin penetration device of an LNG ship and a mounting method of the cabin penetration device, the cabin penetration device of the LNG ship comprises a connecting module and a double-wall pipe, the double-wall pipe comprises an inner pipe and an outer pipe, and the connecting module is fixed at a hole in the upper plane of a deck; the connecting module is provided with a first opening, the inner pipe is arranged in the first opening, the outer wall of the inner pipe is attached to the inner circumferential wall of the first opening, the inner pipe is sleeved with the outer pipe, the outer pipe and the inner pipe are coaxially arranged, and the outer pipe is fixed to the connecting module. The cabin penetration device is beneficial for solving the problem that in the prior art, when a double-wall pipe is directly fixed to a deck, deformation is likely to be caused; according to the technical scheme, the connecting module is firstly fixed to the deck to serve as a connecting foundation of other elements, and the defect that measurement and positioning are difficult when the double-wall pipe is directly welded to the deck is overcome; the inner pipe and the outer pipe are coaxially arranged, so that all connecting parts of the cabin penetration device are evenly arranged, deformation and damage are not prone to occurring, and fuel gas can be smoothly transported.

    本发明公开了一种LNG船的通舱装置及其安装方法,LNG船的通舱装置包括连接模块和双壁管,双壁管包括内管和外管,连接模块固定于甲板的上平面的开孔处;连接模块具有第一开口,内管设于第一开口内,内管的外壁和第一开口的内周壁贴合,外管套设于内管的外部并与内管同轴设置,外管固定于连接模块。该通舱装置有利于解决现有技术中双壁管直接固定于甲板时易造成变形的问题;将连接模块先固定于甲板作为其他元件连接基础的技术方案有利于解决双壁管直接焊接于甲板时测量及定位比较困难的缺陷;内管和外管同轴设置,使通舱装置各连接部件的均匀布置,不易变形和受损并使燃气能够被顺利运输。
