A vessel including a storage tank for storing liquefied gas is disclosed. The vessel comprises: a heat exchanger for heat-exchanging compressed boil-off gas (hereinafter, referred to as "first fluid") by using, as a refrigerant, the boil-off gas discharged from the storage tank, so as to cool the same; a main compression part for compressing a part of the boil-off gas discharged from the storage tank; a rest compression part provided in parallel to the main compression part so as to compress the other part of the boil-off gas discharged from the storage tank; and a decompression device for expanding the first fluid having been cooled by exchanging heat with the boil-off gas, which is discharged from the storage tank, in the heat exchanger, wherein the first fluid is: a flow in which the boil-off gas compressed by the main compression part and the boil-off gas compressed by the rest compression part join; or the boil-off gas compressed by the main compression part.

    L'invention concerne un navire comprenant un réservoir de stockage pour stocker un gaz liquéfié. Le navire comprend : un échangeur de chaleur permettant d'échanger la chaleur de gaz d'évaporation comprimé (ci-après appelé "premier fluide") en utilisant, comme réfrigérant, le gaz d'évaporation évacué du réservoir de stockage, de façon à refroidir ce dernier; une partie de compression principale pour comprimer une partie du gaz d'évaporation évacué du réservoir de stockage; une partie de compression de gaz restant montée parallèlement à la partie de compression principale de façon à comprimer l'autre partie du gaz d'évaporation évacué du réservoir de stockage; et un dispositif de décompression pour provoquer l'expansion du premier fluide ayant été refroidi par échange de chaleur avec le gaz d'évaporation, qui est évacué du réservoir de stockage, dans l'échangeur de chaleur, le premier fluide étant : un flux dans lequel le gaz d'évaporation comprimé par la partie de compression principale et le gaz d'évaporation comprimé par la partie de compression de gaz restant se rejoignent; ou le gaz d'évaporation comprimé par la partie de compression principale.

    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.
