Germany: DNV GL has signed a four-year framework agreement with TenneT to provide project certification for new HVDC substations linked to offshore wind farms in the German North Sea.
Project certification will be performed according to the BSH Standard Design, in order to verify compliance with requirements of the German Federal Maritime and Hydrographic Agency. The agreement includes the certification of the planned DolWin5 converter platform which will link to the Borkum Riffgrund West 1 and 2 and Northern Energy OWP West wind farms.
DolWin5 will connect turbines directly to the offshore platform via 66 kV cables, removing the need for separate substations for each wind farm.
The platform is planned to start operations in 2024.
