Siemens to debut 'extended scope' model at 497MW Hohe See

Siemens will equip the 497MW Hohe See under its first “extended scope” offshore wind deal – an arrangement the German group says will help drive down costs and reduces risks for investors.

As well as 71 SWT-7.0-154 turbines, Siemens will provide project-tailored monopile foundations as part of an end-to-end approach that will also see it provide maintenance services for at least five years.

Canadian energy giant Enbridge today joined German utility EnBW as a 49.9% partner in the €1.8bn ($1.9bn) project, which is due online by the third quarter of 2019 at its site 90km off the island of Borkum.

Siemens said: “The integrated design and installation approach together with the complete solution including turbines, towers, transition pieces and foundations, provides investors with maximum security and confidence regarding the financing and completion of this project.”

Blades for the turbines will come from plants in Hull, UK, and Aalborg, Denmark, with nacelles arriving from Siemens’ new nacelle plant in Cuxhaven, Germany.

Siemens has partnered with specialist contractor GeoSea for delivery of the foundations, which will anchor the 7MW turbines in waters up to 40 metres deep.

Michael Hannibal, Offshore CEO at Siemens Wind Power, said: "The extended scope makes this 497MW 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."

Other contractors on the project include VBMS, which said it has been awarded an €80m inter-array cabling contract.

Hohe See will link to the German grid via the BorWin3 offshore link.
