Siemens will provide the complete offshore wind power plant solutions for the Hohe See offshore wind project 90 km north of the German island Borkum. The inter-array cabling contract with a value of approximately € 80 million has been awarded to VBMS.
The Hohe See offshore wind project is the largest German offshore wind farm to date. It will stretch over an area of 40 km². The 71 wind turbines to be installed at the site will have a combined capacity of just less than half a Gigawatt. 50,1 % of the park is owned by the EnBW The other 49,9% are owned by Enbridge Inc. Both companies agreed on joining forces during the construction of the project and afterwards.
Siemens started to develop the project-specific solution for the foundations of the wind power plant last year. As a result they came up with a monopile design with a length of up to 80 m and a weight of up to 1,500 t to anchor the wind turbines solidly into the sea bed at a water depths of up to 40 m. These foundations as well as the transitions pieces will be delivered by Siemens’ partner GeoSea.
After the final investment decision at the end of 2016, the construction works are going to start in early 2018 and are expected to be finished in the third quarter of 2019.
