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 dynamic behaviour of the structure based on finite element method. A fatigue damage assessment is performed employing the S N approach. The uncertainties in loading and structural response are accounted for to evaluate the probability of failure. The results of 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.
