Abstract
A method for predicting remaining useful life of a wind or water turbine or component determines in step (116) an accumulated damage for the turbine or component and compares this in step (118) to preset damage limit obtained in step (114). This provides a simple approach to estimating remaining useful life, giving the turbine operator an indication of the condition of turbines or farms under management.

30. A method for determining damage to one or more rotating machines including drive trains, generators, or gear boxes of wind turbines or water turbines, or components thereof, the method comprising the steps of:
-
providing data relating to one or more operating conditions; providing one or more damage coefficients relating to the one or more operating conditions; and calculating the damage as a function of the one or more operating conditions and the one or more damage coefficients. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. A method for calculating a damage coefficient for a wind or water turbine or a component thereof, the method comprising the steps of:
-
assessing damage to the wind or water turbine or a component thereof under rated operating conditions and under a plurality of field operating conditions; calculating the damage coefficient from the expected life under rated conditions and the expected life caused under the plurality of field operating conditions; wherein the step of assessing damage comprises the step of providing information on the wind or water turbine or a component thereof. - View Dependent Claims (48, 49)
