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 easily accessible, in-house, all-in-one database is supplemented with pre-conducted analyses relevant for planning, operating, and designing offshore wind farms.
DHI adopted the meteorological data from the global Climate Forecast System Reanalysis (CFSR) and validated it for accuracy and consistency in Northern Europe. Simulations of water level and current conditions were conducted using MIKE 21 flow model with boundary conditions from Global Tide model and meteorological forcing from CFSR. The third generation wind-wave model (MIKE 21 SW) applied full spectral boundary conditions from global spectral wave model and wind forcing from CFSR.
A certifying company closely followed the process of establishing and validating the data basis and analyses methodologies.
