Abstract
A method to control at least a first and a second parallel hybrid driveline arranged to drive a marine vessel is provided. Each driveline comprises a first propulsion unit operatively connected with a second propulsion unit to drive a propeller shaft and produce a thrust force. At least one control unit controls each first and second propulsion unit in all the parallel hybrid drivelines.The method involves individual adjustment of the rotational speed of the first propulsion unit in each driveline to improve the efficiency of this first propulsion unit while maintaining the requested vessel speed, and a simultaneous adjustment of the load from the second propulsion unit in each driveline to improve the efficiency of each driveline and the complete driveline installation.
