Disclosed is a vessel comprising a storage tank for storing a liquefied gas. The vessel according to the present invention comprises: a heat exchanger for cooling a compressed evaporation gas (hereinafter referred to as a first fluid) by exchanging heat with an evaporation gas discharged from the storage tank as a refrigerant; a main compression unit for compressing a part of the evaporation gas discharged from the storage tank; an auxiliary compression unit, installed in parallel with the main compression unit, for compressing another part of the evaporation gas discharged from the storage tank; and a decompression apparatus for expanding the first fluid cooled by exchanging heat with the evaporation gas discharged from the storage tank in the heat exchanger. The first fluid is: a flow in which the evaporation gas compressed by the main compression unit and the evaporation gas compressed by the auxiliary compression unit are merged; or the evaporation gas compressed by the main compression unit. According to the present invention, evaporation gas re-liquefaction performance can be improved.

    액화가스를 저장하는 저장탱크를 포함하는 선박이 개시된다. 상기 선박은, 상기 저장탱크로부터 배출되는 증발가스를 냉매로 하여, 압축된 증발가스(이하, '제1 유체'라고 한다.)를 열교환시켜 냉각시키는 열교환기; 상기 저장탱크로부터 배출된 증발가스의 일부를 압축시키는 주압축부; 상기 주압축부와 병렬로 설치되어, 상기 저장탱크로부터 배출된 증발가스의 다른 일부를 압축시키는 여분압축부; 및 상기 열교환기에서 상기 저장탱크로부터 배출되는 증발가스와 열교환되어 냉각된 상기 제1 유체를 팽창시키는 감압장치;를 포함하고, 상기 제1 유체는, 상기 주압축부에 의해 압축된 증발가스와 상기 여분압축부에 의해 압축된 증발가스가 합류된 흐름; 또는 상기 주압축부에 의해 압축된 증발가스;이다.
