Fugro has started an unexploded ordnance survey at the site of Iberdrola's consented 476MW Baltic Eagle offshore wind farm in the German Baltic Sea.

Once any UXO has been cleared from the site, Fugro will carry out a geotechnical seabed investigation and borehole drilling.

The scope of the €10m contract also includes a programme of standard and advanced laboratory testing, Fugro said.

Fieldwork is scheduled to run until February next year, with the vessels Fugro Pioneer (pictured) and Fugro Scout on the job. Fugro will also deploy the Geobor-S piggy back drilling system.

Fugro project manager Erik Vogt said: “Our drilling set-up ensures that we deliver data of the highest quality to Iberdrola and obtain it in a safe manner.

“Starting with the Fugro Pioneer we’ll clear the sites of any UXO risks efficiently and assure timely commencement of the geotechnical operations.”

The data generated during the campaign will be used to design the foundations for the wind turbines and offshore substation, which will be installed in water depths of up to 45 metres.

Baltic Eagle will cover an area of 35 square kilometres, some 30km off the coast of the German island of Rugen.

Iberdrola already operates the 350MW Wikinger wind farm in the Baltic Sea and won the capacity rights for the 476MW Baltic Eagle and 10MW Wikinger Sud projects in the second offshore wind power tender in Germany earlier this year.
