Abstract
The propulsion unit includes a frame construction having an upper portion forming a support arm protruding from a hull of the vessel and a lower portion forming a longitudinal compartment provided with a propeller shaft having at least one propeller attached thereto, and a first electric motor driving the propeller shaft. The method includes measuring vibrations of the propulsion unit with at least one measuring device, forming a first auxiliary torque control signal based on the measured vibration signal, adding the first auxiliary torque control signal to a first torque control signal produced by a first torque controller of the first electric motor. The first auxiliary torque signal acts against the measured vibrations.
