PROBLEM TO BE SOLVED: To provide a carrier ship which reduces heat entered from the exterior into a tank and thereby inhibits decrease of an amount of a liquefied gas loaded therein.SOLUTION: A carrier ship 10 includes: a tank 12 for storing a liquefied gas; a ship body 11 having a tank storage part for storing the tank 12; a tank cover 13 covering the tank storage part and the tank 12; a heat insulation material 20A which is provided so as to cover the tank 12; and a differential pressure generating part 30 which generates a differential pressure between a first space S1 and a second space S2 so that an air pressure of the first space S1 between the tank cover 13 and the heat insulation body 20A becomes larger than an air pressure of the second space S2 between a surface 12f of the tank 12 and the heat insulation body 20A.SELECTED DRAWING: Figure 2
【課題】外部からタンクへの入熱を抑え、積み荷である液化ガスの量の減少を抑える。【解決手段】運搬船10は、液化ガスを貯蔵するタンク12と、タンク12を収容するタンク収容部を有した船体11と、タンク収容部およびタンク12を覆うタンクカバー13と、タンク12を覆うように設けられた断熱材20Aと、タンクカバー13と断熱体20Aとの間の第一の間隙S1の気圧が、タンク12の表面12fと断熱体20Aとの間の第二の間隙S2の気圧よりも大きくなるように、第一の間隙S1と第二の間隙S2とに差圧を発生する差圧発生部30と、を備える。【選択図】図2
