The document discusses the need for artificial islands in the North Sea to support the growing offshore wind energy industry. It notes that the Netherlands plans to develop 6000 MW of offshore wind by 2020 and 15,000 MW in the future. Neighboring countries Germany and the UK also have large offshore wind ambitions. Artificial islands could serve as hubs for construction, operations and maintenance of offshore wind farms, as well as sites for offshore electrical infrastructure. Potential locations discussed include areas called "North Clay-land", "North-East Friesland" and "IJmuiden op zee". The document outlines an initial design for such islands and their potential functions and benefits.
