Arnhem, The Netherlands, February 8, 2010 — Energy consulting and testing firm KEMA has won the open European tender on the Front End Engineering Design Study (or FEED study) for two offshore wind farms in the North Sea.
German utility EnBW Energie Baden-Wurttemberg AG issued the tender. Once fully operational, the wind farms will have a maximum capacity of 1,200 MW and produce about 4.5 billion kWh per year, which is equal to the annual consumption of 1.2 million households.
The two wind farms are vital in the realization of the German wind energy target — up to 25,000 MW installed capacity of offshore wind energy by 2030 — and should be realized on December 31, 2015.
The results of the FEED study will provide major input and basis for EnBW’s further project planning and investment decisions.
The two offshore wind farms will be situated about 85 kilometers north of the island Borkum. The total capacity of the two wind farms will be up to 1,200 MW depending on the final wind farm layout and wind turbine generator (WTG) design. The total area of the farms is 105 square kilometers with water depth between 38 and 40 meters.
KEMA will be responsible for the set-up and evaluation of several design concepts, such as the park layout, WTG selection, foundation types, platform concepts, installation procedures and maritime logistics.
This information will provide major input for the design of the OWF, which will be according to the specifications of the Bundesamt fur Seeschifffahrt und Hydrographie — the German Federal Office for Sea Shipping and Hydrography.
The project return will be optimized due to the consideration of total cost of ownership: purchasing, erection, operation and decommissioning with risk and sensitivity analyses.
Major subjects are operation and maintenance, including crew transfer concepts, vessel types, helicopter transport, and accommodation platforms.
