The present invention relates to a direct current distribution electric propulsion ship. More specifically, the present invention relates to direct current distribution electric propulsion ship including: a propulsion unit which provides propulsion to the hull; an engine unit which generates the power necessary to operate the propulsion unit; and a battery unit which supplies power to start the engine unit. The propulsion unit, engine unit, and battery unit are formed of a direct current-based power system. A liquefied petroleum gas (LPG) engine generator, which is equipped to operate an engine using LPG as fuel and convert it into electric power, can reduce fuel consumption by controlling the rotation speed according to the amount of power required by the propulsion unit.
