The offshore wind farm Albatros (OWP Albatros) is an offshore wind farm in the German Exclusive Economic Zone (EEZ) in the North Sea over 100 kilometers north of the East Frisian coast. The wind farm is owned by EnBW Energie Baden-Württemberg and the Canadian energy company Enbridge and has an installed capacity of 112 MW . For this purpose, 16 wind turbines of the type Siemens SWT-7.0-154 with a nominal output of 7 MW each were built.
Location and facility
The wind farm is to be built in the south-eastern North Sea, north of the island of Borkum and west of Heligoland in the vicinity of the OWFs " Global Tech I " and " EnBW Hohe See ", within the German EEZ. The distance to Helgoland and Borkum is about 105 kilometers each. The wind farm will extend over an area of 39 km².
division
After the OWP Albatros until November 2015 when the free connection capacity was distributed to the converter platforms "BorWin beta" and "BorWin gamma" by the Federal Maritime and Hydrographic Agency (BSH), instead of the 316 MW applied for, a total of just 116.8 MW (50 MW for the Albatros test field and 66.8 MW for the OWF Albatros), EnBW decided to develop the wind farm in two phases ( Albatros phase 1 with 116.8 MW and Albatros phase 2 with an expected 278 MW). The profitability of phase 1 was questioned because of the comparatively low capacity. In order to guarantee the necessary connection capacity for phase 2, EnBW is expected to take part in the auction of 1,550 MW grid connection capacity by the BSH in 2017.
The wind farm (phase 1) was officially put into operation in January 2020.
technology
Originally, 79 wind turbines in the 5 to 7 MW class were to be built. The planned hub height was between 90 and 94 meters, the diameter of the rotors should be more than 120 meters.
The wind farm was to become a test field: Ten of the 79 approved wind turbines were to be set up on so-called gravity foundations, which do not require deep foundations.
For phase 1, 16 directly driven offshore turbines SSWT-7.0-154 from Siemens Gamesa for 7 MW will be used on monopiles , which will also be serviced by Siemens Gamesa from 2019 for an initial five years.
Here, for the first time in a German wind farm, the Offshore Transformer Module (OTM) from Siemens was to be used instead of a conventional transformer platform , which achieves cost savings during construction through weight reduction.
| Construction year | number | Type | operator | Hub height | Rotor diameter | Performance per system |
|---|---|---|---|---|---|---|
| 2019 | 16 | Siemens SWT-7.0-154 | EnBW / Enbridge | 105 m | 154 m | 7.0 MW |
Network connection
The wind turbines are connected to a transformer platform in the wind farm via medium-voltage cables , 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 BorWin2 offshore HVDC system operated by the transmission system operator Tennet TSO via a submarine cable connection . The Veja Mate and Deutsche Bucht offshore wind farms are also connected to the BorWin beta converter platform . After conversion into direct current , the transmission takes place over 200 km (of which 125 km submarine cable and 75 km underground cable ) to the converter station Diele bei Diele (Weener) . The BorWin2 offshore HVDC system was supplied by Siemens , is designed for a connected load of 800 MW and went into operation in 2015.
operator
On August 17, 2011, granted the Federal Maritime and Hydrographic Agency of Northern Energy OWP Albatros GmbH , one of 14 project companies of the group Northern Energy , the license for the construction and operation of the wind farm with 79 wind turbines. The ownership of the 14 project companies was transferred in 2011/2012 to two holding companies owned by the Austrian STRABAG SE and Northern Energy (First and Second North Sea Offshore Holding).
The OWP Albatros was developed by the Norderland / Northern Energy group of companies . This group of companies is based in Aurich and has specialized in project development in the field of renewable energies with a focus on offshore wind energy. The company is significantly involved in the approval and implementation of the offshore projects Global Tech I and Merkur with 80 and 66 wind turbines respectively in the North Sea.
In December 2014, EnBW announced that it would take over the OWP project.
Maintenance ship
Siemens Gamesa and EnBW are using a special ship to maintain the Albatros and Hohe See offshore wind farms . The Bibby Wavemaster Horizon offers space for a crew of sixty, including up to 40 technicians, and can be on the road for up to a month in the wind farm before it has to return to its home port of Emden . The equipment for the workforce includes a fitness studio, an on-board canteen, a cinema and an on-board hospital. In order to enable the easiest possible transition from the ship to the platforms of the wind turbines, the ship has a height-adjustable, extendable gangway. The gangway is accessed via an elevator, the exit height of which is continuously adjustable between 9.5 and 28.5 m. The ship also has a special crane, the control of which automatically compensates for the ship's movements. Spare parts can be stored on pallets on the ship's foredeck. The service speed of the ship is 13.8 knots (approx. 25 km / h). The ship was officially put into operation in Hamburg in October 2019.
