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

Claim (Index 3):
The ship comprising an engine according to  claim 1 , further comprising:\n a second 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 second gas/liquid separator is sent to the storage tank and the gaseous BOG separated by the second gas/liquid separator is sent to the self-heat exchanger.
