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