RWE Innogy has completed installation of the offshore substation at its 295MW Nordsee Ost wind farm in the German North Sea.
It took the 1800-tonne platform three days to reach the project site some 30km north of the island of Heligoland after it left the Bladt Industries facility in Aalborg, Demark. A floating crane placed the unit on its foundation on SaturdayÂ (pictured).
â€œThe substation was developed and built within a 16-month time frame by our contractor Bladt Industries, together with the Danish subcontractors Semco and ISC,â€ said RWE project manager Matthias Esken.
â€œWe are now going to connect the substation with the previously installed inter-array cables and the TenneT export cables, which remain to be installed.â€
RWE project director for Nordsee Ost Marcel Sunier added: â€œThe heart of the wind farm has now been installed with the transformer substation. As soon as access to the grid has been provided we will start the commissioning.â€
The 48-turbine Nordsee Ost is expected to be complete by year-end with the testing phase to be finished in spring 2015.
