Update 26 November 2019: Installation of the first of two Mono Buckets at our Deutsche Bucht project has been paused due to a technical issue and for further evaluation. As the Mono Bucket installations are part of a pilot project designed to test this technology, this pause does not impact the 31 turbines that make up the main project. - end-
Deutsche Bucht is the first offshore wind farm worldwide to test the Mono Bucket under commercial operating conditions, topped with 8.4 megawatt turbines. The Mono Bucket foundation structure consists of a single steel cylinder, known as a “suction bucket”, upon which is mounted a shaft. 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. This results in benefits for the environment, including less disruption for local porpoise populations, and the ability to completely decommission the Mono Bucket. The Mono Bucket concept has been in development by Universal Foundation
since 2001, based on experience gained from the oil and gas industry. The new foundation structure has already been successfully used in applications such as the foundations for offshore met masts.
