Provided is a cryogenic liquid transport ship in which liquefied ammonia or a cryogenic liquid of a substance liquefied at a cooling temperature equal to that of the liquefied ammonia is housed in a tank, the cryogenic liquid transport ship having a tank structure integrated with a ship body, the construction time being less than that of an LPG ship or an LNG ship, and the economical efficiency being improved. The tank (3) is configured from one or more tank structures (31) comprising a plurality of partition walls formed by mainly using flat-plate-shaped low-temperature steel plates to construct the inner side of the inner shell (12) and the inner side of the upper deck (14). The tank structure (31) is covered with a heat insulating material (7). A connecting structure (4) for connecting the inner shell (12) and the upper deck (14) with the tank structure (31) is formed by using a stainless steel plate. The tank is provided with one or more reliquefaction devices (8) for liquefying gas generated in the one or more tank structures.
本发明提供一种低温液体运输船,通过在罐内收容有液化氨或以与液化氨同等的冷却温度液化的物质的低温液体的低温液体运输船采用与船体一体型的罐式的结构,与LPG船或LNG船相比,建造的工夫较少,而且能够提高经济性。利用由主要使用平板状的低温用钢板构筑在内壳(12)和上甲板(14)的内侧而成的多个隔壁构成的一个以上的罐构造物(31)来构成罐(3)。利用绝热材(7)覆盖罐构造物(31)。使用不锈钢板构成将内壳(12)以及上甲板(14)与罐构造物(31)连结的连结构造物(4)。相对于罐设置有使在一个以上的罐构造物内产生的气体液化的一台以上的再液化装置(8)。
