Disclosed is a vessel including a storage tank. The vessel including the storage tank includes: a first compressor compressing natural gas supplied from the outside of a system; a first cooler cooling the natural gas compressed by the first compressor; a first expander expanding a part of the natural gas passing through the first compressor and the first cooler; a second expander additionally expanding a fluid passing through the first expander; a first heat exchanger heat exchanging the natural gas and cooling the natural gas; an expanding unit expanding the fluid passing through the first heat-exchanger; a second compressor compressing the fluid used as a refrigerant in the first heat exchanger; a second cooler cooling the fluid passing through the second compressor; and a first valve installed on a line transferring evaporation gas in the storage tank to the first heat exchanger and controlling a flow rate and a pressure of the evaporation gas transferred from the storage tank to the first heat exchanger. The first heat exchanger uses: the fluid expanded by one or more among the first expander and the second expander by being divided after passing through the first compressor and the first cooler; and the evaporation gas discharged from the storage tank, as the refrigerant. So, the first heat exchanger can cool the other part of the natural gas divided after passing through the first compressor and the firsts cooler. The present invention is to provide the vessel including the storage tank, wherein the natural gas is returned to the storage tank as the liquefied natural gas itself is used as the refrigerant, without an additional cooling system.
