The Wikinger wind farm is an offshore wind farm (OWP) in the German Exclusive Economic Zone (EEZ) of the Baltic Sea , consisting of 70 wind turbines . It should provide electricity for 350,000 households. This corresponds to more than 20% of the electricity consumption of Mecklenburg-Western Pomerania. The wind farm was built by the Spanish energy supplier Iberdrola around 35 kilometers northeast of the island of Rügen . The investment costs amount to 1.4 billion euros.

location

The wind farm is located on the northeastern edge of the German EEZ in the Baltic Sea, 25 nautical miles southwest of the Danish island of Bornholm , and approximately 7 nautical miles northwest of the Adlergrund. It stands on an area of ​​34 square kilometers. The water depths in the area of ​​the wind farm are around 32 to 42 meters.

The Arkona-Becken Südost offshore wind farm with 60  wind turbines is located directly southeast of the wind farm .

history

At the request of Arcadis Consult GmbH in Rostock on September 19, 2002, the first approval for the construction and operation of the then Ventotec Ost 2 wind farm with 80  wind turbines in the EEZ was granted on May 16, 2007 by the responsible Federal Maritime and Hydrographic Agency granted to Ventotec Ost 2 KG . On September 28, 2015, Iberdrola Renovables approved the modified wind farm, which now comprises 70 turbines .

In February 2016, a safety zone was set up around the construction site at sea with no entry for unauthorized vehicles around the planned locations of the external wind turbines. As a result, construction of the wind farm could begin in March 2016. On August 8, 2016, the transformer platform in the Navantia shipyard in San Fernando (Spain) was completed. It was then shipped to the construction area of ​​the Baltic Sea and erected there in August. The establishment of the jacket foundations and the laying of the Innerpark cabling were completed in January 2017. The first wind turbine was installed in February 2017. By July 2017, half of all systems had been installed, and the last system was installed at the end of October. Trial and set-up operations for all turbines began on December 29, 2017. At the end of October 2018, the wind farm was officially inaugurated.

technical structure

Foundations

The foundations were installed with the special ship "Giant 7". They came from the Spanish town of Aviles. The jacket foundations were anchored up to 40 meters deep into the sea floor. The water depth there is around 31 to 43 meters.

Wind turbines

The wind turbines each have an installed capacity of 5 megawatts. These are Adwen AD 5-135 systems. The rotor diameter is 135 meters. In total, the park with its 70 systems has an output of 350 megawatts. One turbine is 165 m high, the rotor has a diameter of 135 m with three blades, each 67.5 m long, and the nacelle weighs 222 t.

The systems were preassembled in the equipment port Mukran Port on Rügen and from February 2017 mounted on the foundations with the help of the installation ship " Brave Tern ".

Network connection

The transformer platform with the name “Andalucía” rests on a jacket foundation made of six piles and weighs a total of 8,500 tons.

The 70 wind turbines are connected at 33 kV medium voltage level to the transformer platform in the wind farm, which transforms the electricity to a maximum voltage of 220 kV . From there, the current is concentrated on the three-phase alternating current - submarine "Ostwind 1" in the substation to Lubmin transferred to the mainland. Ostwind 1 consists of three pipeline systems, each system is 90 km long at sea and 3 km on land. The 50Hertz Offshore company is responsible for the grid connection .

There is also an electrical connection to the “Arkona” transformer platform in the neighboring Arkona offshore wind farm .

Vikings south

In the tender for grid connection capacity in April 2018, Iberdrola was awarded a 10 megawatt for expansion.

business

Iberdrola has been using a site in Mukran Port at berth 1 as a maintenance and service point for 25 years . This is where the company building is located, built by the Goldbeck construction company . At the end of March 2017, the building was officially opened by the Mecklenburg-West Pomerania Energy Minister Christian Ebene .

The operation of the wind farm is intended to avoid the creation of 600,000 tons of CO 2 per year. The project will create 100 direct and indirect jobs.
