Abstract
A system for alleviating variations in torsional loads applied to a shaft coupled to a main engine of a marine vessel, said shaft is coupled to a propeller of the marine vessel, the system comprising an electric motor-generator configured to provide power to the shaft or take out power from the shaft; a controller coupled to the electric motor-generator said controller is configured to execute instructions, comprising: measuring a group of values that are indicative of torsional loads applied on a shaft of the marine vessel over time; creating a time-based series of values that represent a predictive time-based torsional loads on the marine vessel; collecting readings indicative of power provided by a main engine of the marine vessel; computing an intervention time series of power values to be outputted by the electric motor-generator; wherein the electrical power outputs the intervention time series values of power to the shaft.
