DanTysk is an offshore wind farm in the North Sea . It is located in the German Exclusive Economic Zone around 70 km west of the island of Sylt and covers an area of ​​71 km² with water depths of 21 to 31 meters. The wind turbine DT 22 is the northernmost land point in Germany.

The wind farm has been feeding electricity into the German power grid since December 2014; it was officially opened on April 30, 2015 by Federal Minister of Economics, Sigmar Gabriel .

history

On March 7, 2000, the Gesellschaft für Energie und Oekologie mbH , based in Enge-Sande, applied for the construction and operation of 300  wind turbines (WTs) with a capacity of 5  MW each . With a decision dated August 23, 2005, the construction and operation of the wind farm with 80 wind turbines was approved as a pilot phase by the Federal Maritime and Hydrographic Agency (BSH) on the basis of the Marine Plant Ordinance .

In April 2007 Vattenfall Europe New Energy GmbH bought the rights to the DanTysk project . With the founding of Vattenfall Europe Windkraft GmbH in 2009, the execution of the wind farm was transferred to a company of the Vattenfall Europe Group founded specifically for wind energy. Originally planned was the construction of a total of 300 wind turbines with a capacity of up to 1500 MW. Due to the building permit, the originally planned area was divided up, directly to the west of the approved field “DanTysk” the wind farm project “Nordpassage” with also 80 wind turbines from Vattenfall Europe Windkraft is currently being further developed.

Stadtwerke München has held a 49% stake in DanTysk since October 2010 .

Construction progress

The geophysical investigations and the subsoil explorations were completed in September 2009, and most of the contract tenders were awarded in mid-2011 . Originally, systems with a capacity of 5 MW were planned, but ultimately Siemens SWT-3.6-120 turbines with a capacity of 3.6 MW and a rotor diameter of 120 m, a hub height of 88 m and a total height of 148 m were used. The nearby Danish town of Esbjerg served as the base port for the construction of the wind farm , where the machine houses supplied by Siemens were initially stored.

On December 1, 2012, a safety zone was set up around the expanded construction site (500 m around the external wind turbines), and construction work began in February 2013. The installation ship Seafox 5 shuttled between Vlissingen (Netherlands), where monopiles and so-called transition pieces were loaded, and the construction site, where these were rammed as a foundation and set up. The main contractor is the Danish-German Aarsleff Bilfinger Berger Joint Venture (ABJV). Work on the inner-park cabling is also ongoing, and the wind turbines will be installed on the foundations from November 2013.

At the end of July 2013, the DanTysk OSS transformer platform from Rotterdam arrived on the construction site and was then erected at the planned location on the eastern edge of the wind farm.

In mid-December 2013, all 80 foundations were set up. The construction of the wind turbines began in mid-April 2014; in July 2014, 40 of the 80 planned systems had already been installed. The last turbine was installed at the end of August. Test operation began in early December, and the wind farm officially went into operation in April 2015.

Living platform

The wind farm - so far unique in a German offshore wind farm - was equipped with a living platform for the service staff. There is space for up to 50 people on this platform; it is manned by technicians every 14 days during operation. The construction was commissioned by the Rendsburg shipyard Nobiskrug , it began in summer 2013 at the sister shipyard Abu Dhabi MAR in Kiel and was later completed by Emder Werft und Dock GmbH (EWD). In June 2016, the “DanTysk OAP” platform, which cost around 100 million euros, was installed by the crane ship Stanislav Yudin next to the transformer platform. The foundation for this, a steel jacket construction around 40 meters high, was built at the North Sea Works in Emden. The residential platform is expected to house the technicians of the neighboring offshore wind farm Sandbank .

Network connection

The 80 wind turbines are connected via medium voltage cables to the DanTysk OSS transformer platform in the wind farm, which transforms the three-phase alternating current (three-phase current) from 33  kV to high voltage of 155 kV. From there, the electricity is fed to the SylWin1 offshore HVDC system operated by the transmission system operator Tennet TSO via a 10 km long submarine cable connection . The Butendiek and Sandbank offshore wind farms are also connected to the SylWin alpha converter platform . After conversion into direct current , the transmission takes place over 205 km (160 km of which are submarine cables and 45 km of underground cables ) to the Büttel converter station . The HVDC system called SylWin1 is designed for 864 MW and went into operation in 2015.

Others

The FINO 3 research platform is located directly to the west of the construction site .
