The BARD Engineering GmbH is a company which specializes in the development , the production , the turnkey construction and operation of offshore - wind turbines had pioneering role. The group of seven companies employed up to 1000 people.

In the summer of 2013, the company completed the first commercial offshore wind farm (OWP) in the German North Sea with BARD Offshore 1, despite entering new technological territory and with considerable delay and unexpectedly high costs . In November 2013, the company announced that it would transfer the operation of the OWP BARD Offshore 1 to a new operating company (Off-Shore Wind Solutions) and give up the remaining business operations due to a lack of follow-up orders; only around 300 employees will continue to be employed in the newly founded company.

history

BARD Engineering was founded in September 2003 with the aim of developing and building offshore wind farms by the Russian-German investor Arngolt Bekker , who was successful in the energy sector in Russia after the dissolution of the Soviet Union . BARD means " B Ekker A rngolt R ussia D erm". Up until 2009, Bekker invested around 100 million euros in its own funds in Emden and Cuxhaven .

BARD Engineering had a 5 MW wind turbine (WEA) developed (BARD 5.0) from the engineering office Aerodyn Energiesysteme in Rendsburg . Until 2012, this was mainly assembled from supplied components at the Emden location , with the rotor blades being manufactured in-house. First of all, two prototypes were built for test purposes at the Rysumer Nacken wind farm near Emden. Another plant was commissioned in October 2008 in the onshore area near the shore off Hooksiel north of Wilhelmshaven on a tripile foundation designed by BARD . From 2008 the wind turbine type was in series production. In February 2011 the generator nacelles of the systems on the Rysumer Nacken were replaced by a new development with a nominal output of 6.5 MW.

In 2009 the construction of the first commercial wind farm BARD Offshore 1 began in the area of ​​the German EEZ in the North Sea . It is about 60 km² and is located around 90 km northwest of the island of Borkum . In the final stage, it should achieve a capacity of 400 MW, distributed over 80 wind turbines (WTs) of 5 MW each. High costs, unexpected technical difficulties and weather-related delays in the construction of the wind farm led to high losses and rapidly growing financing requirements. At the end of 2010 the company shares in Bekkers (87%) were transferred to a trustee against the background of an impending insolvency ; at the same time, Bekker left the company. In the 2011 financial year, the group had a loss of 164 million euros with negative equity of 840 million euros. Under a new management, however, the financing of the BARD Offshore 1 wind farm was secured.

In August 2013, the offshore wind farm was inaugurated about two years later than originally planned. Another offshore wind farm called “ Veja Mate ” was also in the planning stage . The area of ​​this wind farm is in the immediate vicinity of BARD Offshore 1, thus also about 90 km north of Borkum and is also expected to generate 400 MW. In addition, further approval applications have been submitted to the Federal Maritime and Hydrographic Agency (BSH). Three wind farms were also planned in the Dutch part of the North Sea. In September 2013, three BARD Engineering offshore wind farm projects in the North Sea were taken over by PNE Wind, which is also active in the wind energy sector, for EUR 17 million.

In November 2013, the company announced that it would cease operations due to a lack of follow-up orders and investors. Around 300 employees are to be taken over in the newly founded company Off-Shore Wind Solutions (OWS), whose task will be the operation and maintenance of the BARD Offshore 1 wind farm. The Group's properties and ships will also be handed over to this company.

technology

Prefabricated rotor nacelles of type BARD 5.0 ​​in Emden

With the "BARD 5.0", BARD manufactured a wind power plant specially designed for offshore use and thus for high wind speeds. The plant has a hub height of 90 meters and a rotor diameter of 122 meters and is conventionally equipped with a gearbox . It reaches its nominal output from 12.5 m / s wind speed and is switched off from 25 m / s. A system built according to this concept with a nominal output of 6.5 MW was under development at the end of the 2000s.

The prototypes of the WEA BARD 5.0 were set up and tested on land on the Rysumer Nacken rinsing field on the Knock west of Emden in 2007 . In autumn 2008, another prototype was first installed in the water in the outer jade off Hooksiel north of Wilhelmshaven . A BARD tripile foundation was set for the first time . The energy generated is supplied to the Wilhelmshavener gas and electricity works via a 20 kV line.

  • The BARD 5.0 gondola belongs to the 5 megawatt class and has a mass of 280 tons. The cut- in wind speed (v in ) is 3 m / s, the nominal wind speed (v r ) 12.5 m / s. The cut-off wind speed v out (600 s average value) is 25 m / s, the cut-off wind speed v A (1 s average value) is 30 m / s. The gondola is designed for a service life of 20 years.
  • The nominal power (electrical output) of the generator , a double-fed asynchronous machine , is 5,276.2 kW, the nominal torque (input) 42.9 kNm, the nominal speed 1,212 min −1 . The efficiency at nominal power is 0.968.
  • The gearbox consists of two planetary stages and a spur gear stage. The transmission ratio is 1:97, the nominal power (input) is 5,630 kW. The nominal torque (input) is 4,300 kNm. The efficiency at nominal power is 0.970.
  • The rotor blades, made of glass fiber reinforced plastics based on epoxy resin , have a blade mass (including blade connection) of approx. 28.5 t and a maximum blade depth of 5.96 m. The hub mass (including pitch bearings and equipment) is approx. 70 t with a hub height of 90 m, the rotor circle diameter 122 m.

The three-legged foundations ( tripile foundations ) required for anchoring on the seabed are a special construction. They are mounted on ram pipes, which in turn are driven about 30 meters into the seabed. The steel elements, each weighing around 500 tons, were manufactured by Cuxhaven Steel Construction (CSC), which is part of the BARD Group. A special ship with the so-called SWATH technology was designed for the supply and maintenance work at sea , which was built at the Abeking & Rasmussen shipyard in Lemwerder . The installation vessel Wind Lift I was designed and built for the erection of the wind turbines on site and their anchoring on the seabed, which can stand on the seabed if necessary and be extended to a height of 45 meters, so that work can be carried out without the influence of waves and at a sufficient distance from the Sea surface becomes possible.

Structure of the company

BARD Emden Energy

The BARD Emden Energy GmbH & Co. KG in Emden led with just under 400 employees (2009) final assembly of the wind turbines of the proprietary type BARD 5.0 through and made even the GRP rotor blades. According to press reports, production was closed in September 2012 due to a lack of follow-up orders; some of the employees have been taken over by other companies in the BARD Group.

Cuxhaven Steel Construction

Port facility with monopiles in Cuxhaven

The Cuxhaven Steel Construction GmbH (CSC) operated from April 2008 in Cuxhaven with approx. 360 employees (2009) the series production of the steel foundation structure developed by the BARD Group for offshore wind turbines, the so-called "BARD Tripile". The support structure developed and patented by Cuxhaven Steel Construction is suitable for water depths of 25 to around 50 meters. The support cross and struts are welded from flat steel elements. The connection zones between the support cross and the three driven piles were bonded with special concrete. Business operations ceased on April 30, 2013. Approx. 25 employees were accommodated in another BARD company.

BARD Building

The BARD Building GmbH & Co. KG took over the installation of wind farms. The special crane ship " Wind Lift I " was commissioned for this purpose .

BARD service

The BARD Service GmbH was established for the operation of wind farms. The company with 94 employees (2009) maintains an operations and service center in Emden. In the “ BARD Offshore 1 ” wind farm, a maintenance team is stationed around the clock in the residential unit of the transformer platform and has the Natalia Bekker offshore wind farm tender .

BARD logistics

The BARD Logistik GmbH dealt with all transport tasks, in particular the transport of the material to the construction sites of offshore wind farms, including the export and import processing, the manning of ships, the transfer of personnel by helicopter and boat, the so-called housekeeping for the BARD ships and Platforms as well as the complete supply and disposal of all units.
