RWE Innogy has placed the inner-park substation of the 295MW Nordsee Ost wind farm on its jacket foundation.
"The substation was developed and built within a 16 month time frame by our contractor Bladt Industries, a steel construction company, together with the Danish subcontractors Semco and ISC," said Matthias Esken, project manager for the transformer substation at Nordsee Ost.
"We are now going to connect the substation with the previously installed inner-array cables and the TenneT export cables which remain to be installed."
As soon as access to the grid has been provided, RWE Innogy will start commissioning the wind farm, which is expected to be complete at the end of this year.
Nordsee Ost will feature 48 Senvion 6.2M126 turbines, the installation of which started earlier this month. The wind farm is located about 35km north of the island of Heligoland.
Alternating current (AC) power from Nordsee Ost and the nearby Meerwind Süd/Ost wind farm will be fed to the already-installed HelWin1 converter platform, where it will be transformed into direct current (DC) to be shipped to land via a 85km cable.
