Disclosed is a fuel gas supplying system, capable of effectively disposing of or using evaporation gas. According to an embodiment of the present invention, the fuel gas supplying system includes: a storage tank accommodating liquefied gas and the evaporation gas of the liquefied gas; an evaporation gas supplying line including a compression unit compressing the evaporation gas and supplying the evaporation gas compressed by the compression unit to a first engine; a reliquefaction line diverging from the evaporation gas supplying line and including an evaporation gas cooling unit receiving and cooling a part of the compressed evaporation gas, an expansion valve decompressing the evaporation gas cooled by the evaporation gas cooling unit, and a gas-liquid separator separating the evaporation gas decompressed by passing through the expansion valve into a gas component and a liquid component; and a refrigerant line. The refrigerant line includes: a compressor compressing a refrigerant; a cooling unit heat-exchanging the refrigerant compressed by the compressor with at least one among the evaporation gas of a front end of the compression unit of the evaporation gas supplying line and the gas component separated by the gas-liquid separator; and an expander decompressing the refrigerant heat-exchanged by the cooling unit. The evaporation gas cooling unit heat-exchanges the evaporation gas supplied with the refrigerant decompressed by the expander of the refrigerant line, and cools the evaporation gas.
