A sandy seabed at Borkum Riffgrund 1 makes it an ideal environment to test the pilot foundation type.

The suction bucket foundation is designed so that it can be installed quickly and removes the need to drive monopiles into the seabed. It is also considered to be more environmentally friendly and reduces costs. 

A Siemens 3.6MW turbine will be installed on the jacket by the end of October.

The UK government’s Carbon Trust as part of the Offshore Wind Accelerator (OWA) programme has backed the full-scale demonstration project.

In January, the Carbon Trust awarded £6 million (EUR 7.3 million) to Dong to build the suction bucket foundation.

Members of the OWA, including E.on, Mainstream Renewables, Scottish Power Renewables, Statkraft and Statoil will be able to use the data from the project and see how it is manufactured and installed, and evaluate the design.
