Installation of the 70 Adwen AD 5-135 turbines at the Wikinger offshore wind farm in the German Baltic Sea has been completed and commissioning works are underway. This project located off the north-eastern coast of the island of Rügen and is solely owned by utility company Iberdrola.

Since February 2017 Fred. Olsen Windcarrier's jack-up installation vessel Brave Tern has been on site to install the 70 turbines. The vessel has been operating out of the Port of Sassnitz-Mukran where it was repeatedly loaded with turbine components including the 135m pre-assembled rotors.

Installation of the project's four legged jacket foundations was completed on the 2^nd January by Offshore Windforce, a subsidiary of Royal Boskalis Westminster N.V. Installation began in April 2016 and was carried out using the Taklift 4 and Giant 7 heavy lift vessels. The foundations stand in water depths between 37-43m and were manufactured by Navantia, Windar and Bladt Industries.

Following the completion of construction, Iberdrola is moving its Wikinger operations to a bespoke operation and maintenance building in the port of Sassnitz.

Adwen is progressing with the start-up of the turbines, each with a 5MW capacity, which will be operating in 'island mode' whilst the project waits for the energisation of the grid connection, expected by the end of 2017.

50Hertz, the transmission system operator responsible for connecting offshore wind farms in the German Baltic Sea to the mainland, is currently executing the final cable laying works and the technical testing for the grid connection.

According to Iberdrola, the construction of the project saw the creation of some 2,000 jobs during construction. Components for the wind farm were manufactured, mainly in Germany, Denmark and Spain.

With an investment of close to €1.4bn, Wikinger will have a 350MW capacity and it is anticipated to generate enough electricity to meed the demands of 350,000 German households. This represents more than 20% of the energy demand in the local region of Mecklenburg-Western Pomerania, according to Iberdrola.

Iberdrola's subsidiary, ScottishPower Renewables is currently in the process of developing the East Anglia One offshore wind in the British North Sea. It is poised to be one of the world’s largest offshore wind farms when it begins operation in 2020. With a budget of £2.5bn and 90% of the supply contracts already awarded, the 714MW project is anticipated to be capable of meeting the electricity demands of more than 500,000 British homes.

In France, Iberdrola is also developing the Bay of Saint-Brieuc offshore wind farm project, off the coast of Brittany. The project will consist of 62 turbines, each with an 8MW capacity, to be installed 20km offshore.

The company stated that all these investments highlight its commitment to the development of renewable energy. Iberdrola explained renewable capacity as of 30th September 2017 stands at nearly 29GW with two thirds of the group’s generation capacity being emissions free.
