Denmark is on the way to ramp up its offshore wind energy production, with a 2020 climate agreement that initiated the realisation of the world’s first two energy islands. The largest of the two planned energy islands will be located in the North Sea, home to some of the greatest wind conditions for offshore wind energy in the world. DHI provides comprehensive metocean studies as part of the site conditions assessment.

 

As Denmark’s national transmission system operator for electricity and natural gas, Energinet is developing and will operate the electricity infrastructure for the two future energy islands. Offshore wind turbine generators will surround the artificial island which will be constructed on a shallow bank. To ensure safe construction, Energinet called for a detailed metocean assessment covering the development area for the artificial island and surrounding wind farms. This metocean assessment will be used as the basis for the tender design of the energy island, as well as in later analyses and design phases of the island and cable export corridors.

 

With extensive knowledge of the metocean conditions in the Danish North Sea, DHI is providing a comprehensive, high-quality metocean assessment report for Energinet based on high-resolution hindcast data, available measurements and historical records. DHI will simulate more than 43 years of metocean conditions through MIKE Powered by DHI’s 2D hydrodynamic and spectral wave models. Local project datasets will be populated to DHI's Metocean Data Portal for data access, download, analytics and visualisation. DHI’s in-house approach to studying storm statistics will enable a more accurate analysis of the properties of extreme storm events.
