A ship includes a main pipe that guides CNG whose pressure is increased by an LNG pump to the engine; a pressure sensor that measures the pressure of CNG to be supplied to the engine; a pressure adjustment valve that adjusts the pressure of the CNG to a set pressure according to engine load; a differential pressure sensor that measures a differential pressure before and after the pressure adjustment valve; and a buffer tank that absorbs a variable pressure of the CNG in the main pipe. The discharge pressure of the LNG pump is controlled such that the differential pressure is increased when the pressure is low, and the differential pressure is decreased when the pressure is high.
