Offshore wind

50Hertz Offshore, a subsidiary of 50Hertz Transmission, has awarded a new contract to Prysmian Group for offshore wind grid-connections in Germany.

The contract, worth €730m, covers designing, producing and installing power cable systems for the offshore wind park cluster West of Adlergrund in the German Baltic Sea.

The contract also includes options for grid connections in value of approximately €250m.

The West of Adlergrund connection projects will involve the design, supply and installation of multiple high voltage submarine cable systems between planned offshore wind parks, around 40km north-east of the island of Ruegen, to the Lubmin substation in north-east Germany (and consequently with the mainland electricity grid) along a route of around 90km (submarine) and 3km (land).

"The production and installation of the West of Adlergrund cable systems will start in 2015."

The Group’s centres of technological and manufacturing excellence for submarine cables in Pikkala (Finland) and Arco Felice (Naples, Italy) will manufacture the 220kV HVAC 3-core extruded cables (including fibre optic cable system).

With the help of the newly upgraded Cable Enterprise DP 2 ship, marine cable laying will be performed.

The production and installation of the West of Adlergrund cable systems will start in 2015.

Prysmian Powerlink CEO Marcello Del Brenna said, "This new project is the fourteenth secured by the Group and further highlights not only the Group’s strategic role to support the realization of important development plans in the field of renewable wind power, but also the entire power transmission industry’s trust in Prysmian’s capability and expertise as a provider of submarine and land cable systems."
