Name and Location
Wikinger offshore wind farm project, northern Europe.

Client
Iberdrola.

Project Description
The Wikinger wind farm will be built about 75 km from the German coast, in water ranging from 37 m to 43 m deep.

It will be the largest wind farm ever developed by Iberdrola. The wind farm will have a capacity of 350 MW to meet the electricity requirements of more than 350 000 households in Germany.

The project will comprise seventy 5 MW turbines and one offshore substation.

Each turbine will have a rotor diameter of 135 m and a swept area of 14 326 m². The turbine foundation will comprise a four-legged jacket and four piles.

The offshore substation will consist of a multistorey topside, installed on a steel jacket substructure that is fixed to the seabed using steel piles. The substation is expected to have a life of 25 years.

Wikinger’s turbine generation will be increased from 33 kV to 220 kV at the substation, before being transported to an onshore substation using two high-voltage export cables.

The energy produced will eliminate nearly 600 000 t/y of carbon dioxide emissions.

Value
Not stated.

Duration
Operations are scheduled to start in 2017.

Latest Developments
ArcelorMittal’s plant in Gijón, Spain, will supply 23 000 t of heavy plate for the construction of 29 jacket foundations for the wind farm in the Baltic sea. Shipments will be delivered between March 2015 and March 2016.

Installation of the jackets – which help to anchor the turbine to the seabed and are suited for installation in deep water – will start in the first quarter of 2016 and are expected to be completed in the second half of the year.

Key Contracts and Suppliers
Areva (supply of M5000-135 wind turbines, as well as maintenance services for five years); Navantia (part of the turbine foundations for the wind farm and metallic structures for the offshore substation); the COWI-IMS joint venture (design basis and the preliminary design for the foundation structures); Royal Boskalis Westminster and Volker Stevin International (transport and installation of the wind turbine foundations and the offshore substation piles; Volker Stevin International (port logistics); Bilfinger (contract for testing the steel foundations and developing the piling template); SAL Heavy Lift (subcontracted by Bilfinger for the transportation and installation of the test piles and equipment); Gardline Group and GEO (full geological survey of the project site to determine the foundation requirements); and ArcelorMittal (supply of heavy plate).
