The technical challenges for offshore wind turbine foundations are colossal, as the wind industry needs to go bigger, further and deeper into the ocean. Before the end of this decade, we are likely to witness wind turbines of 20MW and rotor diameters beyond 250m, with wind farms 200Km far from the shore and water depths beyond 60m. These turbines also imply larger supporting structures, and manufacturers are already working on the next generation of fixed foundations. What are the foundation design challenges and methods to deal with the next generation of offshore wind turbines?
