Disclosed is a liquefied gas regasification system. According to an embodiment of the present invention, the liquefied gas regasification system comprises: a refrigerant circulation line circulating and supplying a refrigerant, and including a circulation pump pressurizing and circulating the refrigerant, a refrigerant evaporator gasifying the pressurized refrigerant by exchanging heat with seawater, a liquefied gas gasifier performing the heat exchange between the gasified refrigerant and the liquefied gas supplied from a liquefied gas storage tank, and a refrigerant storage tank storing the refrigerant passing through the liquefied gas gasifier; a first liquefied gas supply line connecting the liquefied gas storage tank, the liquefied gas gasifier, and a first demand source, and supplying the liquefied gas from the liquefied gas storage tank to the liquefied gas gasifier; a refrigerant cooling line branched from a part between the refrigerant evaporator and the liquefied gas gasifier of the refrigerant circulation line and connected to the refrigerant storage tank, and having a refrigerant cooler; and a bypass line placed between the refrigerant storage tank and the refrigerant evaporator of the refrigerant circulation line, and connected to bypass the circulation pump. With the liquefied gas being supplied to the liquefied gas gasifier through the first liquefied gas supply line, when the pressure in the refrigerant storage tank exceeds a set value, the refrigerant supplied from the refrigerant storage tank is circulated to the refrigerant cooling line through the bypass line, is cooled by the refrigerant cooler, and is stored in the refrigerant storage tank, and when the pressure in the refrigerant storage tank is normal, the refrigerant supplied from the refrigerant storage tank is supplied to the liquefied gas gasifier through the refrigerant circulation line and is allowed to exchange heat with the liquefied gas. The present invention aims to provide a liquefied gas regasification system which is capable of improving energy efficiency for regasifying liquefied gas.
