The present invention relates to a system and a method for regasifying a liquefied gas of a liquefied gas regasification vessel, which can increase an energy efficiency by recovering cold heat wasted while regasifying a liquefied gas and producing electric power. The system for regasifying the liquefied gas of the liquefied gas regasification vessel according to the present invention comprises: a vaporizer for vaporizing the liquefied gas by heat exchange with a first heat transfer medium; a trim heater heating the regasified gas transferred from the vaporizer to a gas demander to a temperature required by the gas demander by the process of exchanging heat with a second heat transfer medium; a second heat exchanger heating the second heat transfer medium by exchanging heat between the second heat transfer medium to be supplied to the trim heater and a first heat source; and a first heat exchanger vaporizing the first heat transfer medium by exchanging heat between the first heat transfer medium to be supplied to the vaporizer and the second heat transfer medium heated in the second heat exchanger.

    본 발명은 액화가스를 재기화시키면서 버려지는 냉열을 회수하여 전력을 생산함으로써 에너지 효율을 높이는 액화가스 재기화 선박의 액화가스 재기화 시스템 및 방법에 관한 것이다. 본 발명에 따른 액화가스 재기화 선박의 액화가스 재기화 시스템은, 액화가스를 제1 열전달 매체와 열교환시켜 기화시키는 기화기; 상기 기화기로부터 가스 수요처로 이송되는 재기화 가스를 제2 열전달 매체와 열교환시켜 상기 가스 수요처에서 요구하는 온도로 가열하는 트림히터; 상기 트림히터로 공급할 제2 열전달 매체와 제1 열원을 열교환시켜 상기 제2 열전달 매체를 가열하는 제2 열교환기; 상기 기화기로 공급할 제1 열전달 매체와 상기 제2 열교환기에서 가열된 제2 열전달 매체를 열교환시켜 상기 제1 열전달 매체를 기화시키는 제1 열교환기;를 포함한다.
