A new energy saving pump control system has been developed for ship. This system consists of a cooling sea water pump, control valve of sea water line, microcomputer, transistor inverter, etc. While conventionally the pump is run continuously at a given speed and surplus sea water is supplied with various auxiliary machineries in many conditions, this new developed system provides proper amount of sea water with auxiliary machineries by the control valve and variable speed pump with a microcomputer and transistor inverter.
The first plant of this system was installed on the container ship and we confirmed that the function of this system was satisfactory.
