The present invention relates to a system and a method for regasifying liquefied gas of a ship, wherein electric power is produced by recovering low-temperature heat while regasifying liquefied gas, thereby increasing the ship's energy efficiency. The system for regasifying liquefied gas of a ship in accordance with the present invention comprises: a gasifier for gasifying liquefied gas through heat exchange with a first heat transfer medium; a trim heater for heating regasified gas transferred from the gasifier to a gas consumer to a temperature required by the gas consumer through heat exchange with a second heat transfer medium; a first cycle for circulating the first heat transfer medium; and a second cycle for circulating the second heat transfer medium. The first cycle comprises: a first heat exchanger for gasifying a first heat transfer medium to be supplied to the gasifier through heat exchange with a heat source; and an expansion generator for producing electric power by expanding the first heat transfer medium gasified by the first heat exchanger. The second cycle comprises a second heat exchanger for heating the second heat transfer medium to be supplied to the trim heater through heat exchange with the heat source.

    본 발명은 액화가스를 재기화시면서 냉열을 회수하여 전력을 생산함으로써 에너지 효율을 높이는 선박의 액화가스 재기화 시스템 및 방법에 관한 것이다. 본 발명에 따른 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 제1 열전달 매체를 순환시키는 제1 사이클; 및 상기 제2 열전달 매체를 순환시키는 제2 사이클을 포함하고, 상기 제1 사이클은, 상기 기화기로 공급할 제1 열전달 매체를 열원과의 열교환에 의해 기화시키는 제1 열교환기; 및 상기 제1 열교환기에서 기화된 제1 열전달 매체를 팽창시켜 전력을 생산하는 팽창 발전기를 포함하며, 상기 제2 사이클은, 상기 트림히터로 공급할 제2 열전달 매체를 열원과의 열교환에 의해 가열하는 제2 열교환기를 포함한다.
