Following the 497-MW order for the EnBW Hohe See offshore wind-power plant, EnBW has also awarded Siemens Gamesa Renewable Energy (SGRE) with the installation of the neighboring 112-MW project EnBW Albatros in the German North Sea.
The scope of supply includes 16 direct-drive SWT-7.0-154 wind turbines on monopile foundations and the grid connection via a Siemens Offshore Transformer Module (OTM). Siemens Gamesa will install both wind-power plants in parallel, with installation starting in spring 2018.
The projects are located 90 km north of Borkum Island in the German North Sea, with water depths of up to 40 m. After commissioning in 2019, SGRE will initially provide service and maintenance for the turbines over a period of five years.
EnBW Albatros is the first German offshore wind-power plant that Siemens will supply as a full-scope project. It also serves as entry of the compact Siemens OTM, which reportedly allows a reduction in weight and size of more than 30% compared to a conventional AC substation, into the German market. EnBW Albatros will be connected to the power grid via the Borwin Beta HVDC converter-platform, which is located approximately 25 km away and has been delivered by Siemens as well.
Siemens is partnering with the Belgian offshore-construction specialist GeoSea for construction and installation of the monopiles for both plants. Inter-array cabling and coordination of the construction work remain in the scope of EnBW.
“EnBW Albatros allows us to demonstrate our broad competence in offshore projects, ranging from project-specific engineering services and the beneficial combination of power-generation and transmission technology to service and maintenance concepts,” said Michael Hannibal, CEO offshore of SGRE. “This project has a high relevance for us since we will turn the 112-MW wind-power plant into a highly profitable investment for our customer via cutting-edge technology and smart details.”
