The present invention relates to a vessel cooling system for saving a fuel, capable of saving total costs due to fuel consumption by properly controlling the fuel consumption amount of a diesel generator operating a seawater pump and the fuel consumption amount for improving combustion efficiency of a main engine. The vessel cooling system for saving a fuel comprises: a seawater supply line having the seawater pump and circulating seawater; a clean water supply line heat-exchanged with the seawater supply line by a clean water cooler and having a clean water pump circulating the clean water in a heating device of a vessel, wherein the clean water supply line has a first temperature control valve maintaining a fixed temperature of the clean water supplied to the heating device of the vessel; and a main engine cooler line diverging from an inlet of a first temperature control valve in the clean water supply line and including a cooler pump for the clean water to circulate in the main engine of the vessel, wherein the main engine cooler line includes a second temperature control valve maintaining the fixed temperature of the clean water supplied to the main engine of the vessel by setting the temperature of the clean water to be relatively lower than that of the first temperature control valve. The vessel cooling system for saving a fuel includes: a seawater temperature sensor sensing the temperature of the seawater by being installed in the seawater supply line; a clean water temperature sensor sensing the temperature of the clean water by being installed in the clean water supply line; and a controller calculating the difference in temperature value by receiving the temperature value of the seawater temperature sensor and the temperature value of the clean water temperature sensor and controlling the seawater pump for the difference value to reach a setting value by comparing the difference value with the predetermined setting value, thereby controlling the ratio of fuel consumption amount of the seawater pump to the fuel consumption amount of the cooler pump.
