Van Oord has installed the first of 33 foundations at the Deutsche Bucht offshore wind farm.
The foundation, installed in a water depth of approximately 40m, is a monopile fitted with a transition piece.
Of the total 33 wind turbines, 31 will be on monopiles and two will be mono buckets.The latter ae being piloted and will be installed in the second quarter of 2019.
During the pile driving, Van Oord will deploy its Fauna Guard system – an in-house developed acoustic device safely and temporarily deters marine fauna species by using special underwater acoustics.
In addition, a multi-level noise mitigation system will be used during the installation of the monopiles, which includes a hydro sound damper and a double big bubble curtain.
Northland Deutsche Bucht project director Jens Poulsen said: “We are very pleased to have achieved this important milestone. Thanks to the committed Deutsche Bucht project team and our experienced general contractor, Van Oord, the offshore building phase of the wind farm started on schedule.”
The Deutsche Bucht offshore wind farm, located approximately 95km northwest of the island of Borkum in Germany, is being built by the Northland Deutsche Bucht project company.
In 2017 Van Oord was awarded the Balance of Plant contract. The scope consists of the design engineering, procurement, construction and installation of the foundations, inter array cables and offshore substation, and the transport of the wind turbines.
When completed the offshore wind farm will have a grid connection capacity of approximately 269MW. That is sufficient to provide approximately 328,000 households with sustainable energy on an annual basis.
Commissioning of the Deutsche Bucht offshore wind farm is expected to take place in the second half of 2019.
