Kind Code:

A1

Abstract:

Disclosed is a ship comprising a liquefied gas storage tank. A ship comprises: a first compressor which can compress one or more parts of a boil-off gas discharged from a storage tank; a second compressor which is for compressing the other part of the boil-off gas discharged from the storage tank; a propulsion compressor which is for compressing one part of the boil-off gas that has been compressed by means of the first compressor and/or the second compressor; a first heat exchanger which is for heat exchanging the boil-off gas compressed by means of the propulsion compressor and the boil-off gas discharged from the storage tank; a refrigerant decompressing device which is for expanding the other part of the boil-off gas that has been compressed by means of the first compressor and/or the second compressor; a second heat exchanger which is for cooling, by means of a fluid expanded by means of the refrigerant decompressing device as a refrigerant, the boil-off gas that has been compressed by means of the propulsion compressor and heat exchanged by means of the first heat exchanger; an additional compressor which is for compressing the refrigerant that has passed the refrigerant decompressing device and second heat exchanger; and a first decompressing device which is for expanding the fluid that has been compressed by means of the propulsion compressor and then cooled by means of the first heat exchanger and second heat exchanger, wherein the additional compressor is driven by means of power generated from the expanding of the fluid by means of the refrigerant decompressing device.
