Fugro Consult GmbH was commissioned by E.ON to perform the geotechnical exploration for the Arkona-Becken Südost (Arkona) offshore wind farm in the Baltic Sea. The geotechnical investigation was carried out in summer and early autumn 2011 in water depths of approximately 22m to 37m and included 79 boreholes to depths of up to 60m below seabed, with CPT testing undertaken at some wind turbine and offshore substation locations. Fugro deployed the jack-up barge Seacore Excalibur and the geotechnical vessel Fugro Commander during the campaign.
