| Summary: | The work deals with fatigue reliability assessment of an offshore wind turbine supporting structure under combined wind and wave loading. Considering the operational condition of the wind turbine a 3-D scatter diagram for North Atlantic is used to define the sea states and the dynamic behaviour of the structure is determined based on the finite element method. A fatigue damage assessment is performed employing the S-N approach. The uncertainties in the loading and structural response are accounted for to evaluate the probability of failure. The results of the reliability analysis are presented as a function of the offshore wind turbine operational scenarios in a way to allow determining what operating conditions should be avoided. |
