Risk assessment procedure for offshore wind turbine support structures induced by scour was proposed. Probabilistic distribution of scour depth, a hazard curve, was calculated by using the C.S.U formula with parametric uncertainties. To get fragility curves of support structure, dynamic analysis was done with a certain assumed scour depth, given significant wave height and return period. Scour induced failure probability of support structure for a given wave height then can be found by integrating the multiplication of hazard and fragility. It is repeated for possible range of scour depths to form a risk curve. In numerical example, scour induced structural risk of 3MW offshore wind turbine supported by suction bucket foundation is evaluated. The proposed approach can be used in determining wind farm location where scour is significant.
