  • Method and device for controlling energy-saving sailing of ship
    Patent number: 10407148
    Abstract: The present invention discloses a method and device for controlling energy-saving sailing of a ship. The method comprises the steps of changing the operating parameters of the ship correspondingly when the resistance of the ship changes during routine sailing, controlling the current opening degree of a throttle to increase the instantaneous oil supply amount of a main engine of the ship if the resistance of the ship becomes smaller, and controlling the current opening degree of the throttle to reduce the instantaneous oil supply amount of the main engine of the ship if the resistance of the ship becomes larger. Compared with the prior art, the method and device have the advantages that energy waste is reduced greatly and the sailing cost is reduced.
