Abstract: There is provided mechanisms for predicting remaining useful lifetime of a bearing of an electric podded azimuth thruster. A method is performed by a controller. The method includes obtaining operational conditions of the bearing. The method includes predicting the remaining useful lifetime of the bearing using the operational conditions. The lifetime of the bearing is divided in three separate phases. The remaining useful lifetime of the bearing is predicted differently in the three separate phases.
