Prysmian announced that it has won an offshore wind farm contract to supply some 200 km of different cables valued at more than 200 million euros for a North Sea project that it said represents multiple technical milestones.
The contract, a press release said, calls for the Italian-based company to provide the cable to transpower gmbh, a German transmission system operator that is a subsidiary of Dutch grid operator TenneT. The grid connection project, called BorWin2, will link two offshore wind farms (Veja Mate and Global Tech 1) in the North Sea to mainland Germany. The turnkey connection, it said, will link the two parks, located 125 km offshore, to the mainland and enable them to transmit their wind-generated renewable power into the German grid.
The project, the release said, sets several wind farm firsts. One is the first commercial use of ±300 kV DC cables using extruded technology that represent the highest direct-current voltage level ever reached as well as the first 800 MW connection to offshore wind parks and the largest Voltage Sourced Converter (VSC) system, which will also have 800 MW capacity, it said.
The project will use extruded high-voltage, director current (HVDC) cable technology from Prysmian together with Siemens HVDC Plus® converter technology at the offshore platform and onshore stations, the release said. The HVDC connection supplied by Prysmian will include the ±300 kV DC subsea and land cable types along around 125 km submarine plus around 75 km land route (around 200 km in total) to the land converter station in Diele, near Papenburg. A total length of about 39 km of extruded 155 kV HVAC submarine cable connections will complete the connections from the offshore wind park transformer platforms to the offshore converter platform, it said, adding that the submarine cables will be made at Prysmian’s factory in Arco Felice, Italy, and the land cables at its factory in Delft, The Netherlands.
The Prysmian contract is part of a larger contract, worth more than €500 million, awarded to the consortium between Prysmian and Siemens Energy, which will
deliver the VSC system, the release said. It added that Prysmian’s cable-laying vessel, the Giulio Verne, will
be among the specialized vessels used for the various
operations. The HVDC connection, it said, is planned
to commence operation in 2013. |
