A ship comprises: a tank; a multistage compressor for compressing a boil-off gas discharged from a storage tank and comprising a plurality of compression cylinders; a first heat exchanger for heat exchanging a fluid, which has been compressed by the multistage compressor, with the boil-off gas discharged from the storage tank and thus cooling the same; a first decompressing device for expanding a flow ('flow a') partially branched from the flow ('flow a') that has been cooled by the first heat exchanger; a third heat exchanger for heat exchanging, by &#x201c;flow a&#x201d; which has been expanded by the first decompressing device as a refrigerant, the remaining flow (&#x201c;flow a&#x201d;) of &#x201c;flow a&#x201d; after excluding &#x201c;flow a&#x201d; that has been branched and thus cooling the same; and a second decompressing device for expanding &#x201c;flow a&#x201d; which has been cooled by the third heat exchanger.
