    • Lifetime reassessment of offshore wind turbines using meta-models 

      Rolfes, Raimund; Hübler, Clemens; ICASP14; Schmidt, Franziska (2023)
      Offshore wind turbines are usually designed for 25 years. After this period, there are various options regarding the further use of the wind turbines. One option is a so-called lifetime extension, i.e., to continue operating ...

    • Relevance of Uncertainty Modelling for Wind Turbine Lifetime Estimations 

      Rolfes, Raimund; Wosko, Sarah; ICASP14; Hübler, Clemens (2023)
      For the design of wind turbines, the determination of the fatigue lifetime is essential. Frequently, so-called lifetime "damage equivalent loads" (DELs) are used as a measure for the fatigue lifetime. Short-term DELs are ...
