Zusammenfassung:	A method and a system for controlling a propulsive power output applied to a propeller shaft of a ship. The ship includes the propeller shaft and a propulsive power source connected to the propeller shaft. A control signal for producing with the propulsive power source a propulsive power is varied within an interval limited by an upper control limit value and a lower control limit value. If a current value of an operational parameter of the ship reaches a first parameter limit value, the upper control limit value is reduced. Thus, the propulsive power source may be prevented from applying a too high power output to the propeller shaft, which would be unfavourable for the ship.
