Borkum West II

BW

The offshore wind farm "Borkum West II " is a property under construction wind farm in the German Exclusive Economic Zone ( EEZ) in the southern North Sea. Meanwhile, the wind farm is called Trianel wind farm Borkum.

Location

The offshore wind farm is being built on an area of 56 sq km about 45 km north of Borkum Island in water depths of 25 to 35 meters.

Project

From Trianel wind farm Borkum GmbH & Co. KG, Aachen, the construction and operation of 80 individual wind turbine generators (WTG ) of type AREVA Wind M5000 with a nominal output of 5 MW and a total capacity of 400 MW. 33 Stadtwerke participate in the offshore project under the leadership of Trianel GmbH with a total investment of 1 billion euros.

History

The wind farm has been designed from the Prokon North Energy Systems GmbH in Leer. The application for construction and operation of 80 wind turbines of 26 May 2006 in the version of 15 November 2007 ( BSH) approved on 13 June 2008 by the Federal Maritime and Hydrographic Agency. By the end of 2014, 80 wind turbines will be installed.

The contract for the cabling of the individual wind turbines with the substation platform with approximately 65 km of medium -voltage submarine cables has received the North German Seekabelwerke (NSW).

For the first phase of construction was a security zone for the shipping set up in August 2011, so first 40 wind turbines can be set up. This should first go up to the second quarter of 2013 to the network. When ramming of the foundations into the seabed bubble curtain was used to protect harbor porpoises before the construction noise. The installation vessel Oleg Strashnov put the built in WeserWind in Bremerhaven Tripods on the driven into the seabed foundation piles. Two of these 60 m high and up to 900 tonnes of heavy parts were picked up by the crane vessel Stanislav Yudun from offshore terminal Bremer Logistic Group (BLG ) in Bremerhaven and brought to the construction site about 45 km away. End of May 2013 were placed all tripods, since the wind turbines are fetched from the Eemshaven, Netherlands, and built on the tripod foundations. The chartered by the British company MPI installation vessel Adventure conveyed in each case the components for three complete wind turbines on a tour from the mainland to the construction site and assembled it on the tripod. By February 2014, half of the plants was built.

The installation vessel Oleg Strashnov lifted in mid-April 2013, the 2,400 -ton transformer platform ( " BW 0"), Alstom that is already installed on the construction site foundation. The thus constructed transformer station is the heart of the wind farm, here are the 33 kV lines coming together of the 80 wind turbines. The power is transfered down here at 155 kV and are directed to the TenneT grid connection point at about 7.5 km from the HVDC converter platform " DolWin alpha", from there it is passed over the HVDC " DolWin 1" Norderney to the country.

A delay of the network connection by the responsible HVDC transmission grid operator TenneT TSO the first phase of the wind farm is expected to go into operation until 2014.
