The liquefied gas transport ship comprises a ship body, a first type cabin and a second type cabin, the first type cabin and the second type cabin are arranged in the ship body, a gap is formed between the outer wall of the second type cabin and the inner wall of the first type cabin, a first liquid cargo cavity is formed, the second type cabin is provided with a second liquid cargo cavity, and the first liquid cargo cavity and the second liquid cargo cavity are separated from each other; the first type cabin is a film type cabin, and the second type cabin is an A-type independent liquid cargo cabin, a B-type independent liquid cargo cabin or a C-type independent liquid cargo cabin. The pressure in the second liquid cargo cavity is borne by the second type cabin, the pressure in the first liquid cargo cavity is borne by the film type cabin, and a part of the pressure inside and outside the second type cabin can be mutually balanced, so that the pressure borne by the first type cabin and the pressure borne by the second type cabin are small, and the first type cabin and the second type cabin can be made larger and longer; the space utilization rate and the transportation efficiency of the ship body are greatly improved; in addition, liquid in the first liquid cargo cavity can have a cold insulation effect on the second type cabin, and the evaporation rate of the second type cabin is greatly reduced.
本发明公开了一种液化气运输船,包括船体以及设于船体内的第一型舱和第二型舱,第二型舱的外壁与第一型舱的内壁之间具有间距并形成第一液货腔,第二型舱具有第二液货腔,第一液货腔与第二液货腔之间相互间隔开,第一型舱为薄膜型舱,第二型舱为A型独立液货舱、B型独立液货舱或C型独立液货舱。第二液货腔内的压力由第二型舱进行承受,第一液货腔内的压力由薄膜型舱进行承受,第二型舱内外的压力会相互平衡掉一部分,使得第一型舱和第二型舱所承受压力较小,可以将第一型舱和第二型舱做得更大更长,大大提高了船体的空间利用率和运输效率;而且,第一液货腔内的液体可以对第二型舱起到一个保冷效果,大大降低了第二型舱的蒸发率。
