Prysmian Group has secured a new award From 50Hertz Offshore GmbH – a subsidiary of 50Hertz Transmission GmbH, transmission grid operator in Germany – worth approximately € 230 million to design, produce and install a power cable system for the offshore wind park cluster West of Adlergrund in the German Baltic Sea.
The award comes as a result of 50Hertz having exercised an option for a further grid connection already provided for in the existing contract for the West of Adlergrund project. That was originally worth € 480 million, with options for further grid connections to be activated separately, when secured by Prysmian in May 2014.
The project scope comprises the design, supply and installation of multiple high voltage submarine cable systems, now including this additional connection, between planned offshore wind parks located approximately 40 km north-east of the island of Ruegen, to the Lubmin substation in North East Germany along a route of approximately 90 km (submarine) and 3 km (land).
The 220 kV HVAC 3-core extruded cables (including fibre optic cable system) will be produced in Prysmians facilities for submarine cables in Pikkala (Finland) and Arco Felice (Naples, Italy), which have recently been upgraded to be fully equipped to manufacture and test large cross-section 3-core cables up to 400 kV AC. The production of the West of Adlergrund cable systems has already started and installation operations are scheduled to begin in 2015.
Marine cable laying will be performed using the Group’s DP2 ship Cable Enterprise. The vessel has been newly upgraded and converted from barge to self-propelled DP2 vessel able to operate in very shallow waters.
