Spanish energy supplier Iberdrola has awarded a €20M (£16M) steel foundations testing contract for its Wikinger wind farm to German engineering and services group Bilfinger.
The Wikinger offshore wind farm is being developed by Iberdrola in the Baltic Sea, off the coast of the island of Rügen, where the water depths range between 37m and 43m.
In the fall of 2014, Bilfinger will drive steel piles up to 38m long into the seabed at selected locations of the site, which covers roughly 34km², and then carry out tension and pressure tests under water following a static period of several weeks.
Bilfinger will also test noise protection systems to reduce the noise pollution that marine fauna is exposed to during the construction phase to a minimum.
This engineering work complements geological surveys conducted in the last three years, which obtained ample information about the characteristics of the seabed.
After a €1.4bn (£1.1bn) investment, the 70 turbines on the 350-MW wind farm will produce electricity equivalent to the consumption of more than 350,000 German households.
