Abstract

The present invention relates to a control device for a steam supply system for a ship in which a PLC-based integrated control device is provided on an existing steam supply line of a ship, steam is generated via an auxiliary boiler, an exhaust gas boiler, and a steam supply system (ECSS), and fuel oil consumption and greenhouse gas generation can be reduced by adjusting a valve so that the amount of power consumed by the ECSS is optimized for each mode according to the sailing, arrival and departure, or docking of the ship. In addition, the present invention relates to a control device for controlling to allow the normal operation of a main engine by controlling the exhaust gas boiler and valve when the ship is sailing, reduce fuel oil consumption and greenhouse gas generation by controlling the auxiliary boiler, ECSS, and valve when the ship is arriving or departing, and allow the supply of steam by controlling the ECSS and valve when the ship is docked.
