BARD Offshore 1 (BO1) is an offshore wind farm of Ocean Breeze Energy, a subsidiary of Macquarie, in the German Exclusive Economic Zone of the North Sea .
The construction of the wind farm began in June 2009. In December 2010 the first wind turbines supplied electricity to the grid. All wind turbines were supposed to be installed by the end of 2011, but bad weather, technical problems and generally difficult conditions in the construction area caused delays and significantly higher costs than initially calculated. The wind farm was finally completed as the first commercial offshore wind farm in the North Sea at the end of July 2013 and officially opened on August 26, 2013.
location
The offshore wind farm is located on an area of 59 km² approx. 89 km north-west of the island of Borkum and 126 km west-north-west of Heligoland with water depths of approx. 39 to 41 meters.

Project
The construction and operation of 80 individual wind turbines (WTs) with a nominal output of 5 MW each and a total nominal output of 400 MW was approved . The 80 wind turbines will produce around 1.6 billion kWh of electricity annually; enough electricity for approx. 400,000 multi-person households.
The operation of the wind farm is monitored from a control center in Emden . In the offshore field itself there is also a permanently manned residential unit on the "BARD 1" transformer platform .
70% of the rights to the offshore wind farm BARD Offshore 1 were secured by Stadtwerke -Verbund SüdWestStrom Windpark GmbH & Co KG , based in Tübingen, and 30% by WV Energie Frankfurt . The Stadtwerke-Verbund SüdWestStrom withdrew from the project in 2012 because it considered it no longer economical for itself.
The European Commission funded the project as part of the European Energy Program for Recovery (EEPR) with 53.1 million euros.
history
The wind farm with the (first) 80 wind turbines was approved by the Federal Maritime and Hydrographic Agency (BSH) in April 2007 .
In June 2009 the converter platform " BorWin alpha " (inclusion of the systems for HVDC conversion) and in August 2009 the residential and transformer platform "BARD 1" were installed. The start of construction for the first construction cluster with 24 wind turbines in the southern area of the field was in March 2010. The first twelve systems were completed by the beginning of November 2010, eight were in trial and set-up mode. On April 1, 2011, the safety zone that had existed since May 2009 was extended to the north so that construction of the northern building cluster could begin.
Since December 2010, electrical power has been fed into the grid from the first installed wind turbines. In mid-August 2011, 19 of the 80 wind turbines were installed and 16 were connected to the grid. In May 2012, 53 wind turbine foundations were in place, 20 wind turbines were completely set up, 16 of which supplied electricity. At the end of November 2012, a good half of the 80 wind turbines were up and around 25 were in operation. On March 11, 2013, half of the planned 80 wind turbines were connected to the grid, 72 foundations were set and 59 turbine houses were erected. BARD used the installation vessel Wind Lift I with its own large on-board crane to set up the system ; from summer 2012 the Thor jack-up platform was also used, which in turn was supported or replaced by the new JB 117 .
Service and maintenance are carried out by transferring staff from the BARD 1 transformer platform to the respective systems; For the transfer of personnel, the AG Ems (Ems Offshore) uses the tender Natalia Bekker , which is less sensitive to swell due to the SWATH design. In the spring of 2013, the BARD Group chartered the former ferry Regina Baltica to accommodate more than a hundred workers employed in the offshore construction site , initially for six months. The 33-year-old ship was equipped with a helicopter landing deck for this purpose. Equipped with 110 cabins, several restaurants, a fitness studio, a cinema, a lounge and a play room, the 145 m long ship was already used in 2012 for the construction of the British offshore wind farm “Sheringham Shoal”. Every three to four weeks the ship drove to Cuxhaven to collect provisions and fuel.
At the end of July 2013, the 80th and therefore last system was built. At the beginning of August 2013, 65 wind turbines were already delivering electricity. The wind farm was officially opened on August 26, 2013. In December 2013, Ocean Breeze Energy, a subsidiary of HypoVereinsbank , took over operations. In 2017, BARD Offshore 1 was the most profitable German wind farm. With a total of more than 5 TWh of electricity fed into the grid, it is clearly number 1 since commissioning (as of February 2018).
On August 7, 2019, it became known that Macquarie had acquired 100% of the shares in Ocean Breeze Energy from HypoVereinsbank for an undisclosed purchase price.
Accidents
A professional diver from Maersk , a company commissioned by BARD, was killed during the construction work in July 2010 . A fatal accident occurred in January 2012 when a landing platform broke loose for an unknown cause and fell into the water. A worker was torn down. After extensive search and rescue operations in which the DGzRS , the Federal Police and the German Navy were involved, he could only be rescued dead.
Power connection
Innerpark cabling
The individual wind turbines are networked in bundles using medium-voltage cables with which the 33,000 volt three-phase current generated is carried away. These clusters combine up to eight wind turbines and are in turn connected to the heart of the power plant, the transformer platform "BARD 1". The technical systems on this platform collect the electricity generated and convert it to a higher voltage (155 kV) using transformers in order to keep the losses during energy transport to a minimum. The Bremen branch of the Industry Solutions division of Siemens AG supplied this substation , i.e. the high and medium voltage switchgear and transformers, including auxiliary power and emergency power supply and the protection, control and communication technology, for around 13 million euros . The company had delivered a similar system as its first order for the Lillgrund offshore wind farm off the Swedish coast. The BARD 1 platform itself, weighing around 3400 tons, was built at a shipyard in Klaipėda ( Lithuania ).
Forwarding on land by the network operator TenneT
The 155 kV three-phase power line runs from the “BARD 1” transformer platform to the “ BorWin alpha ” converter platform located around one kilometer to the northeast . From here, the offshore wind farm is connected to the German network via a direct current cable connection ( BorWin 1 ) that was set up by the TenneT subsidiary Transpower and whose operation is the responsibility of Tennet Offshore GmbH (formerly E.ON ).
The 3200 tons (plus approx. 1800 tons for the jacket foundation) heavy converter platform " BorWin alpha ", on which the HVDC systems are installed, was built in Vlissingen (NL). The electricity produced in the wind farm is brought from here to the mainland via the HVDC “BorWin 1”. This runs through submarine cables , in the southeast area parallel to the grid connections of the offshore wind farms Borkum West II ( HVDC "DolWin 1" ) and alpha ventus (the latter, however, because of the shorter distance than three-phase current), over the island of Norderney .
The coupling with the 380 kV extra high voltage network of the transmission system operator Tennet TSO takes place via the Diele switchgear .
Operation problems
After several shutdowns in February 2014, the wind farm had to be completely disconnected from the grid for several months from March 2014 due to problems with the power quality and thus the electricity transmission. The troubleshooting was carried out both on the wind turbines and on the transformer and converter stations on the “BorWin alpha” platform of the HVDC “BorWin 1”, which also affected the connection to the OWP “ Global Tech I ” via this HVDC at the same time . At the end of 2014, new software and damping filters were installed in the wind turbines and half of the systems were put back into operation. All other systems were then put back into operation by October 2015, so that the wind farm was back in regular operation as of October 2015.
Trivia
The wireless service provider Vodafone operates in the wind farm, a GSM - and LTE - base station , which ensures in a radius of up to 36 km mobile coverage.
