Sensitivity analysis of the first natural frequency of the offshore wind turbines in the Eneco Luchterduinen wind farm: The differences between the identified and modelled first natural frequency of wind turbines with and without scour protection in varying environmental conditions

In the Dutch coastal waters more and more wind turbines on monopile foundations are built. An important design parameter is the first natural frequency of the wind turbine. The first natural frequency is dependent on environmental conditions and different soil conditions such as scour. This research gives a better insight into the sensitivities...

Gravity Based Foundation: Scour and design optimisation

Within Royal HaskoningDHV an innovative concept is thought to be feasible as a new foundation for larger wind turbines in deeper waters. In this thesis the development of this innovative offshore wind turbine foundation was aided. The research focused on two topics: - Scour at this gravity based foundations. - Possible design optimisations with...

Predicting scour around offshore wind turbines using soft computing techniques

In this report a prediction method is developed for scour around monopiles. A soft computing technique called genetic programming (GP) is used to create a scour prediction formula that can compute scour in all offshore conditions, meaning current-induced, wave-induced and combined current- and wave-induced scour. The GP was trained with an...
