The invention relates to an LNG ship pipe tunnel area ventilation structure which comprises a bow air duct vertically arranged in a bow transverse compartment and a stern air duct vertically arranged in a stern transverse compartment, the upper end of the bow air duct extends to the position above a bow mooring deck, and the upper end of the stern air duct extends to the position above a cargo hold deck above a liquid cargo hold. The bow transverse bulkhead forms a bulkhead wall between the bow mooring deck and the liquid cargo tank, and the bow mooring deck is lower than the cargo tank deck; the lower end of the bow air duct and the lower end of the stern air duct respectively extend to be communicated with the double-layer bottom pipe tunnel area; a blind window is arranged at the upper end of the bow air duct, an exhaust device is arranged at the upper end of the stern air duct, the blind window is installed on a bow mooring deck, and the exhaust device is installed above a cargo hold deck. The bow air duct and the stern air duct are connected with the double-layer bottom duct area to form a ventilation structure, the internal space of the transverse bulkhead is utilized, the specification of the air duct is increased, the requirement for the ventilation quantity is met, and the requirement for the space of the air duct is reduced.

    本发明涉及一种LNG船管弄区域通风结构,包括:竖直设置在艏部横隔舱内的艏部风道、竖直设置在艉部横隔舱内的艉部风道,艏部风道的上端延伸至艏部系泊甲板上方,艉部风道的上端延伸至液货舱上方的货舱甲板上方,艏部横隔舱在艏部系泊甲板与液货舱之间形成分隔舱壁,艏部系泊甲板低于货舱甲板;艏部风道的下端和艉部风道的下端分别延伸连通双层底管弄区域;在艏部风道的上端设置百叶窗,在艉部风道上端设置排风装置,百叶窗安装在艏部系泊甲板上,排风装置安装在货舱甲板上方。本发明通过艏部风道、艉部风道连接双层底管弄区域形成通风结构,利用横隔舱内部空间,增大风管的规格满足通风量需求,降低了风管对空间的需求。
