Abstract
A method for operation of a hybrid propulsion system for a marine vessel, including at least one electric motor and at least one internal combustion engine as drive units, is disclosed. Depending on the requirement, for example the vessel speed, the drive units individually or jointly drive at least one propulsion unit, for example a propeller, the power outputs of the drive units to the at least one propulsion unit controlled by a control device as a function of a set value, for example a set value for the propeller rotation speed or the vessel speed, and an operating mode such that the sum of these power outputs results in a total power being output to the at least one propulsion unit, with this total power output being split between the power outputs of the individual drive units as a function of the set value and the operating mode.
