A method for compensating torsional loads applied to a shaft coupled to a main engine, comprising measuring values indicative of torsional loads applied on the shaft or power demand from the main engine; computing from the values the torsional load over time and a parameter indicative of a cycle; after measuring the group of values, measuring a subsequent value indicative of torsional loads applied on the shaft, and applying a compensating moment or load in a direction determined by whether the subsequent value is greater than or smaller than the value representing the torsional load over time. The direction is a torque direction applied to the shaft by the main engine or the opposite direction.
