In order to reduce costs and increase competitiveness for offshore wind farm developments, DONG Energy wanted to be able to establish local certified MetOcean criteria in less than four months.
To do this, they needed to establish MetOcean conditions for the structural design and operation of offshore wind turbines, substations, and related infrastructure. In close collaboration with DONG Energy, DHI used the expertise gained from developing data sets for the marine and energy industries in the seas of Northern Europe to create an extensive, validated, and documented database. The database is supplemented with pre-conducted analyses relevant for planning, operating, and designing offshore wind farms. The company established, validated, and documented a robust, accurate, consistent long-term data basis through a combination of:
- available meteorological data, in-situ measurements and satellite data
- extensive modelling of hydrodynamic and wave conditions using MIKE Powered by DHI’s MIKE 21 hydrodynamic (HD) – including data assimilation – and 3rd generation spectral wave (SW) models
Together with DONG Energy, they successfully applied the data for several local wind farm projects during the development of the MetOcean database.
