Abstract
The establishment of the Anholt Wind Farm was agreed by the Danish Government in February 2008. The development of the wind farm between Djursland and Anholt governed by Energinet.dk will be based on series of preliminary investigation including environmental assessments studies and geotechnical evaluations of a gross area and two cable corridors. Within this framework geophysical surveys have been performed by The Geological Survey of Denmark and Greenland (GEUS) in the period April to May 2009. The installed capacity of the wind farm of approximately 400 MW will be stored in a transformer platform within the wind farm area before exporting to a connection point onshore at Djursland north of Grena via a submarine cable. The gross area de-limited for the wind farm was surveyed during the latter period but has been reported separately.
The brief objectives of the survey include for the wind farm investigation area and the transformer platform:
- To provide data for the ongoing environmental statement and the subsequent technical development on a various number of different subjects.
- To provide an accurate hydrographical chart of the two potential cable routes
- To map seabed features within the two potential cable routes including natural features and artefacts, obstruction and ship wrecks.
- To provide broad scale seabed classification of surface sediments for a baseline benthic survey.
- To provide information on the shallow geology i.e. mapping the distribution and thickness of the main geological formations.
- To provide information for the marine archaeological assessments of the area.
