Siemens to Provide Full Package for EnBW Hohe See OWF

February 17, 2017

Siemens Wind Power has secured a contract to provide complete offshore wind power plant solutions including foundations for the EnBW Hohe See offshore wind farm.

Starting in early 2018, the Hohe See wind farm will be installed at a site 90 kilometers north of the German island Borkum in the North Sea at water depths of up to 40 meters.

In 2016 Siemens began with the development of project-specific solutions for the foundations of EnBW Hohe See wind farm with a preliminary project. The result was the development of a large monopile design with a length of up to 80 meters and a weight of up to 1,500 tons to anchor the wind turbines solidly into the seabed.

For EnBW Hohe See, Siemens is partnering with logistics specialist GeoSea. The company of the Deme Group will also deliver the foundations including monopiles and transition pieces.

The 71 wind turbines of the type SWT-7.0-154 rated at 7 megawatts each will be manufactured at Siemens’ new nacelle plant in Cuxhaven beginning in mid-2018 and will be shipped to the project harbor in early 2019. The blades will be shipped from factories in Hull, UK, and Aalborg, Denmark, the company noted.

“We are happy to apply our full scope of engineering services at EnBW Hohe See offshore wind project,” states Michael Hannibal, Offshore CEO at Siemens Wind Power. “The extended scope makes this 497-megawatt wind power plant one of the largest projects that we have ever executed. Our customer thereby benefits from the proven experience of a multinational company along the entire value chain of large offshore wind projects.”

Commissioning is planned for the third quarter of 2019. The wind power plant will generate enough power to supply 560,000 households with clean renewable energy.

After commissioning, Siemens will perform service and maintenance of the turbines for a period of five years. Grid connection will be established via the ‘BorWin 3’ high-voltage DC link and ‘BorWin Gamma’ converter platform to be installed by Siemens for grid operator Tennet.
