On the 19th of July Northland Deutsche Bucht GmbH announced that the Deutsche Bucht Mono Bucket pilot demonstrator (“Demo”) project has reached financial close. Deutsche Bucht, which is 100 per cent owned by Canadian power producer Northland Power Inc., will be the first offshore wind farm worldwide to test this new type of foundation structure under commercial operating conditions.
Kristian Ravn, Managing Director of Universal Foundation said: “This pilot provides a unique opportunity to utilize the Mono Bucket foundation in a commercial project, demonstrating the above state of the art technology’s low impact on marine habitats. The support from Northland Power has been second to none. All of the parties involved have invested a lot of effort into making this project a reality, and we are delighted that it will now move forward.”
The advantage of the suction bucket construction is that its own weight and vacuum pressure causes it to become firmly embedded in the sea floor. This method eliminates the need for pile driving, and consequently, for noise mitigation measures such as big bubble curtains. It also enables the possibility for complete decommissioning. Consequently, the result of using this technology is less environmental impact, less interference with ocean wildlife making the Mono Bucket highly attractive in noise restrictive areas. Installation of the Mono Bucket foundations is scheduled for the second quarter of 2019. Commissioning of the wind farm is expected to take place in the second half of 2019.
The foundations will be equipped with V164-8.4 MW wind turbines by MHI Vestas. The two turbines will contribute an additional 17 MW of capacity to the base 252 MW project for a total of 269 MW and 33 turbines.
