Disclosed is a fuel gas control system for a ship. According to one embodiment of the present invention, the fuel gas control system comprises: a boil-off gas supply line which has a first compression unit which pressurizes boil-off gas in a storage tank storing liquefied gas to supply the boil-off gas pressurized by the first compression unit to an engine; a first reliquefying line which includes a second compression unit which receives a part of the boil-off gas pressurized by the first compression unit and pressurizes the boil-off gas, a heat exchange unit which makes the boil-off gas pressurized by the second compression unit exchange heat with the boil-off gas supplied to the first compression unit, a first gas-liquid separator which divides the boil-off gas cooled by the heat exchange unit into gas substances and liquid substances, an expander which is connected to the second compression unit to receive the gas substances of the first gas-liquid separator and to reduce the pressure, and a second gas-liquid separator which receives the boil-off gas, of which the pressure is reduced by the expander, and the liquid substances separated by the first gas-liquid separator, and divides them into gas substances and liquid substances; and a second reliquefying line which includes an expansion valve which receives a part of the boil-off gas pressurized by the first compression unit, cools the boil-off gas by making the boil-off gas exchange heat with the boil-off gas supplied from the heat exchange unit to the first compression unit, receives the cooled boil-off gas, reduces the pressure of the boil-off gas, and supplies the boil-off gas to the second gas-liquid separator. The present invention is able to promote the efficient operation of facilities.
