Extreme winds and waves for offshore turbines

The major objective of the project is to enable more accurate wind and wave forecasts during storms by developing a new model system, which couples the most advanced atmospheric, wave and oceanic models. This is for better design of turbines, more secure operation and more cost-efficient maintenance for offshore wind farms.The research is targeted at the investigation of the coupling strategies for the models and parameterization of the marine atmospheric and oceanic boundary layers. The atmospheric model is the mesoscale Weather Research and Forecasting model and its Large Eddy Simulation mode, WRF-LES. The wave model is the MIKE 21 SW and the ocean model is MIKE 3.The close cooperation between DTU, DHI and Uni.Research of Bergen University gathers together the expertise in the atmospheric modeling, wave and oceanic modeling and the coupling with the direction of wind energy and wave load application for the offshore environment. The expected results include the coupled forecast system for strong wind and wave conditions, new approaches for coupling, improved description of the extreme wind and waves in the Danish coastal zones and better understanding of the impact of coastal waves on the wind profile.
