Nearly all offshore wind turbines are located in relatively shallow water mounted on fixed bottom support structures. These sites have limited high winds and the turbines are usually highly visible – it therefore makes sense to extend wind turbine systems to deeper water. However, fixed bottom support structures are not feasible in deeper water, so it is necessary to explore floating offshore wind turbine (FOWT) systems. FOWT using semi-submersible support structures can experience unacceptably large heave, pitch and roll motions in extreme waves which can affect the performance of the turbine and can cause significant damage. This project will evaluate the potential and effectiveness of applying tuned liquid dampers with anti-heave plates to reduce the motions.
