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 a fluid passing through the first heat-exchanger; a second compressor compressing the fluid used as a refrigerant in the first heat exchanger; and a second cooler cooling the fluid passing through the second compressor. The first heat exchanger cools the other part of the natural gas branched after passing through the first cooler and the first compressor by using the fluid expanded by one or more among the first expander and the second expander as the refrigerant by being branched after passing through the first compressor and the first cooler. The present invention provides the vessel including the storage tank, wherein the natural gas is liquefied by using liquefied natural gas as the refrigerant without an additional refrigerant system and is returned to the storage tank.

    저장탱크를 포함하는 선박이 개시된다. 상기 저장탱크를 포함하는 선박은, 시스템 외부로부터 공급되는 천연가스를 압축시키는 제 1 압축기; 상기 제 1 압축기에 의해 압축된 천연가스를 냉각시키는 제 1 냉각기; 상기 제 1 압축기 및 상기 제 1 냉각기를 통과한 천연가스의 일부를 팽창시키는 제 1 팽창기; 상기 제 1 팽창기를 통과한 유체를 추가적으로 팽창시키는 제 2 팽창기; 천연가스를 자가열교환시켜 냉각시키는 제 1 열교환기; 상기 제 1 열교환기를 통과한 유체를 팽창시키는 팽창수단; 상기 제 1 열교환기에서 냉매로 사용된 유체를 압축시키는 제 2 압축기; 및 상기 제 2 압축기를 통과한 유체를 냉각시키는 제 2 냉각기;를 포함하고, 상기 제 1 열교환기는, 상기 제 1 압축기 및 상기 제 1 냉각기를 통과한 후 분기되어, 상기 제 1 팽창기 및 상기 제 2 팽창기 중 하나 이상에 의해 팽창된 유체를 냉매로 하여, 상기 제 1 압축기 및 상기 제 1 냉각기를 통과한 후 분기된 다른 일부의 천연가스를 냉각시키는 것을 특징으로 한다.
