According to an embodiment of the present invention, a gas regasification system includes: a regasification supply line re-gasifying liquefied gas to supply the gas to a consumer; first and second heat exchangers placed on the regasification supply line; a heat source circulation line supplying a thermal medium for the regasification of the liquefied gas to the first and second heat exchangers; a first seawater heat exchanger exchanging heat between the thermal medium and seawater to supply the thermal medium to the second heat exchanger; a second seawater heat exchanger exchanging heat between the thermal medium discharged from the second heat exchanger and seawater to supply the thermal medium to the first heat exchanger; and a control valve placed between the first and second seawater heat exchangers on the heat source circulation line, and converting the thermal medium from a liquefied state to at least a partially gasified state. Therefore, the present invention is capable of reducing costs and the size of a facility by reducing the diameter of pipes in a thermal medium circulation line. 본 발명의 일 실시예에 따른 가스 재기화 시스템은, 액화가스를 재기화하여 수요처로 공급하는 재기화 공급라인; 상기 재기화 공급라인 상에 마련되는 제1 열교환기와 제2 열교환기; 상기 제1 열교환기와 상기 제2 열교환기에 상기 액화가스를 재기화시키는 열매체를 공급하는 열원 순환라인; 상기 열매체와 해수를 열교환시켜 상기 열매체를 제2 열교환기로 공급하는 제1 해수열교환기; 상기 제2 열교환기에서 배출되는 열매체를 해수와 열교환시켜 상기 제1 열교환기로 공급하는 제2 해수열교환기; 및 상기 열원 순환라인 상에 상기 제2 해수열교환기와 상기 제1 열교환기 사이에 마련되며, 상기 열매체를 액상에서 적어도 일부 기상으로 변환시키는 조절밸브를 포함하는 것을 특징으로 한다.
