Fatigue Stress Estimation for Submerged and Sub-Soil Welds of Offshore Wind Turbines on Monopiles Using Modal Expansion
The design of monopile foundations for offshore wind turbines is most often driven by fatigue.With the foundation here price contributing to the total price of a turbine structure by more than 30%, wind farm operators seek to gain knowledge about the amount of consumed fatigue.Monitoring concepts are developed to uncover structural reserves coming
