Abstract (en)

[origin: WO8203831A1] In a method for controlling the propulsion machinery in a ship having a variable-pitch propeller, the ship's speed is first adjusted to a value within a predetermined interval containing a desired value of the speed. This adjustment is effected by changing the number of revolutions of the propulsion machinery and the propeller pitch, whereupon the number of revolutions and the pitch are changed, while maintaining the speed within the said interval. For each change in the number of revolutions and the pitch, it is checked whether the change has resulted in an increase or a cutdown in fuel consumption. These changes are effected until a combination of the number of revolutions and the pitch is attained, which provides for minimum fuel consumption in the propulsion machinery.
