Abstract:
A ship comprises an engine; a first self-heat exchanger which heat-exchanges boil-off gas discharged from a storage tank; a multi-stage compressor which compresses, in multi-stages, the boil-off gas that passed through the first self-heat exchanger after being discharged from the storage tank; a first decompressing device which expands one portion of the boil-off gas compressed by the multi-stage compressor; a second self-heat exchanger which heat-exchanges the other portion of the boil-off gas compressed by the multi-stage compressor, with the boil-off gas expanded by the first decompressing device; and a second decompressing device which expands the boil-off gas pre-cooled by the second self-heat exchanger and cooled by the first self-heat exchanger, wherein the first self-heat exchanger uses the boil-off gas discharged from the storage tank as a refrigerant for cooling the boil-off gas that passed through the second self-heat exchanger after being compressed by the multi-stage compressor.

Claim (Index 3):
The ship comprising an engine according to  claim 1 , further comprising:\n a liquid/gas separator disposed downstream of the second decompressor and separating liquefied natural gas generated through reliquefaction of the BOG and gaseous BOG from each other, wherein the liquefied natural gas separated by the gas/liquid separator is sent to the storage tank and the gaseous BOG separated by the gas/liquid separator is sent to the first self-heat exchanger.
