A system that can test the safety and performance of the fuel supply equipment using one or more fluids, including nitrogen.

In general, a ship generates thrust by driving an engine, where the engine uses gasoline or diesel to move the piston to rotate the crankshaft by reciprocating movement of the piston, whereby the shaft connected to the crankshaft rotates so that the propeller It was common to let it run.

However, in order to cope with various environmental regulations and reduction of resources, an LNG fuel supply method for driving an engine using liquefied natural gas (Liquefied Natural Gas) as a fuel has recently been used. The use of gas has also been applied to vessels other than LNG carriers.

However, the temperature and pressure required for driving the engine of the ship may be different from the temperature and pressure of the liquefied natural gas stored in the fuel tank, and thus, the temperature and the temperature of the liquefied natural gas stored in the liquid state. The technology for controlling the pressure and supplying it to the ship's engine is being continuously researched. Therefore, LNG fuel tanks including LNG storage tanks, boosting pumps, high pressure pumps, heat exchangers, and engines are utilized. Fuel supply systems are being developed.

Accordingly, there is a need to build a performance test system of fuel supply equipment for securing safety and performance testing of various fuel supply equipment required for the fuel supply system. As the technology for a system capable of testing the safety and performance of the fuel supply equipment on land while using natural gas is somewhat weak, it is also necessary to construct a system capable of testing the safety and performance of the fuel supply equipment.
