Disclosed is a system of boil-off gas reliquefaction for a vessel. The system of boil-off gas reliquefaction for a vessel comprises: a multi-stage compressor for compressing boil-off gas; a heat exchanger cooling the boil-off gas compressed by the multi-stage compressor through heat exchange by using boil-off gas before compression by the multi-stage compressor as a refrigerant; a decompression device installed at the rear end of the heat exchanger to decompress fluid cooled by the heat exchanger; and a detour line making the boil-off gas detour to the heat exchanger so that the boil-off gas can be supplied to the multi-stage compressor.

    선박용 증발가스 재액화 시스템이 개시된다. 상기 선박용 증발가스 재액화 시스템은, 증발가스를 압축시키는 다단압축기; 상기 다단압축기에 의해 압축된 증발가스를, 상기 다단압축기에 의해 압축되기 전의 증발가스를 냉매로 사용하여 열교환시켜 냉각시키는 열교환기; 상기 열교환기 후단에 설치되어, 상기 열교환기에 의해 냉각된 유체를 감압시키는 감압장치; 및 증발가스를 상기 열교환기를 우회시켜 상기 다단압축기로 공급하는 우회라인;을 포함한다.
