Short summary
This study investigates the offshore wind turbine support structure’s fatigue life by a rapid numerical model which considers the effects of scour and a tuned mass damper. An optimization technique is proposed to find the damper's optimal parameters, considering time-varying scour. It is found that the damper optimized by the proposed optimization technique performs better than an initially designed damper in terms of fatigue life enhancement.
