The offshore wind farm "Amrumbank West" is an offshore wind farm that went into regular operation in October 2015 in the German Exclusive Economic Zone (EEZ) of the North Sea .

General

The offshore wind farm was built on an area of ​​32 km² around 35 km northwest of the island of Helgoland and 18 km southwest of the Amrumbank at water depths of 20-25 meters.

Following an application dated June 16, 2000, the construction and operation of the wind farm with 80 wind turbines (WTs) was approved on June 9, 2004 by the Federal Maritime and Hydrographic Agency (BSH) on the basis of the Marine Plant Ordinance . The measuring platform on the southern edge of the construction site was built in 2005.

Operator was initially Amrumbank-West GmbH , an operating company of E.ON . With the commissioning of the wind farm in 2015, Amrum-Offshore West GmbH became the new operating company. It has been part of RWE Renewables GmbH since the end of 2019 .

The 80 Siemens SWT -3.6-120 wind turbines have a nominal output of 3.78  MW and a rotor diameter of 120 meters (the length of a rotor blade is 58.5 meters). They are to be used to generate electricity for 300,000 households. The investment volume was around 1 billion euros.

The Nordsee Ost and Meerwind offshore wind farms are not far south of the Amrumbank West construction site .

The opening ceremony took place in February 2016 at an event in the Hamburg Harbor Museum in the presence of Johannes Teyssen ( CEO of E.ON), Olaf Scholz ( First Mayor of Hamburg), Uwe Beckmeyer ( Parliamentary State Secretary at the Federal Ministry for Economic Affairs and Energy ), Jörg Singer ( Mayor of Helgoland) and Dominik Schwegmann (project manager).

construction

In preparation for construction, soil investigations were carried out with the research ship Ice Beam in the planned construction site in summer 2012 . After setting up a 500 m safety zone around the planned outer locations of the wind turbines to secure the wind farm construction site, construction work began on site in May 2013.

From January 2014, the 80 up to 300-tonne monopile- type steel foundations were driven into the seabed. For bringing and installation of 80 monopile elements from Cuxhaven the large, six-legged came up vessel MPI Discovery is used, which has been chartered by E.ON for the construction of offshore wind farms.

On February 11, 2015, the first turbine was installed with the help of the MPI Adventure installation ship, which is bringing seven turbines from Esbjerg on the Danish coast . The wind turbines were then gradually commissioned in parallel with the installation of further systems. The first systems fed electricity into the grid in April 2015. The wind farm was fully commissioned in October 2015.

The 80 wind turbines are connected to a transformer platform in the wind farm via around 100 km of medium-voltage cables , which transforms three-phase alternating current (three-phase current) from 33 kV to high voltage of 155 kV. From there, the electricity is fed via a submarine cable connection to the HelWin2 offshore HVDC system operated by the transmission system operator Tennet TSO . The Kaskasi offshore wind farm with an output of 325 MW is also connected to the HelWin beta converter platform . After conversion into direct current, it is transmitted over 130 km (including 85 km of submarine cables and 45 km of underground cables ) to the converter station in the Büttel substation near Büttel (Elbe) .

business

RWE has been using a site on Heligoland as a maintenance and service point for 28 years .
