The invention provides a liquefied gas carrier with the width smaller than 32.3 m, and the liquefied gas carrier comprises a cargo hold structure arranged in a ship body; the cargo hold structure comprises a plurality of liquid tanks and a protection cabin, wherein the protection cabin is located on the outer sides of the liquid tanks and comprises a vertical section arranged on the inner side of a side plate of the ship body and a horizontal section arranged on the inner side of a bottom plate of the ship body, the vertical section is communicated with the horizontal section, and the top of the vertical section is not higher than an upper deck of the ship body; and the protection tank can be used as a water ballast tank, an oil tank or a void tank. The protection cabin is mainly applied to the Panama-type liquefied gas carrier of 2.30-5.30 thousand cubic meters, by arranging the protection cabin comprising the vertical section and the horizontal section, the gravity center of the whole carrier can be effectively lowered, the cabin breaking stability of the liquefied gas carrier under the ballast working condition is improved, and on the premise that the main scale frame of the carrier is limited, the cabin capacity of the cargo cabin is increased, and the division of protection cabin groups is reduced.

    本发明提供了一种液化气船,其宽度小于32.3m,包括设置在船体内的货舱结构,所述货舱结构包括多个液罐和保护舱,所述保护舱位于所述液罐的外侧,其包括设置在所述船体的侧板内侧的垂直段和设置在所述船体的底板内侧的水平段,所述垂直段和水平段相连通,所述垂直段的顶部高度不高于所述船体的上甲板的高度;所述保护舱可用作压载水舱、油舱或空舱。本发明主要应用于巴拿马型的2.3万‑5.3万方液化气船,通过设置包括垂直段和水平段的保护舱,可有效降低整船重心,改善一种液化气船在压载工况下的破舱稳性,并在船舶主尺度框架被限定的前提下,增加货舱舱容,同时减少保护舱组的划分。
