Financial close has been reached for two pilot wind turbines at the Deutsche Bucht Offshore Wind Farm.
The project will test Mono Buckets, a new type of foundation structure, equipped with a 8.4 MW turbine. In addition to its Balance of Plant contract for the wind farm, Van Oord will also be responsible for manufacturing and installing the two additional Mono Bucket foundations.
Northland Deutsche Bucht announced yesterday that the Deutsche Bucht Mono Bucket pilot demonstrator project has reached financial close. Deutsche Bucht, the third North-Sea offshore wind farm to be built by Canadian power producer Northland Power, will be the first wind farm worldwide to test this new type of foundation structure under commercial operating conditions.
The Mono Bucket foundation consists of a single steel cylinder, known as a ‘suction bucket’, upon which a shaft is mounted. A transition piece and an 8.4-megawatt wind turbine will be installed on this shaft. The suction bucket structure becomes firmly embedded in the sea floor by its own weight and vacuum pressure, eliminating the need for pile driving and, consequently, for noise mitigation measures such as big bubble curtains. The new structure therefore benefits the environment because it causes less disruption to local porpoise populations and can be completely decommissioned at the end of its lifetime.
