Geotechnical surveys have been launched for the 240MW Jammerland Bugt offshore wind farm in Denmark.
The project is located in the Bay of Jammerland, bordered by the municipality of Kalundborg in Denmark, and is owned by TotalEnergies (85%) and European Energy (15%).
After several months of geophysical surveys, scanning the seabed using 3D measurements, new geotechnical surveys have been initiated to form the basis for the final design of the wind farm project in preparation for the actual construction work.
Geotechnical surveys involve sampling the seabed via boreholes in the area where the wind turbines are to be installed, as well as along the cable corridor to land.
The aim is to obtain detailed knowledge of the seabed conditions so that foundations and cable routes can be planned accurately and safely.
“The geotechnical surveys provide us with knowledge about the conditions of the seabed itself and are therefore a crucial step in the actual design of the wind farm,” said Zhanar Dreisig, asset manager for TotalEnergies Denmark.
“Unlike geophysical surveys, these surveys are actual drillings at the individual wind turbine positions and in the cable routes for the power cables to the turbines.”
When the surveys at Jammerland Bugt are completed in July, the mobile drilling platform, a so-called jack-up, will be moved to the Lillebælt Syd area to continue work on the Lillebælt Syd offshore wind farm.
“The launch of the geotechnical surveys marks an important step in translating the planning work into physical progress at sea,” said Andreas Karhula Lauridsen, vice president and head of offshore wind at European Energy.
“These investigations are essential for ensuring that the final design is both technically sound and well-adapted to local conditions.”
Later this year, further surveys will be carried out for Jammerland Bugt, both at sea and on land, in connection with the planning of the export cables that will run from the offshore wind farm to shore. These investigations are expected to continue until September.
The wind farm project will comprise 16 turbines with a height of 256 metres and capacity of 15MW each.
TotalEnergies and European Energy have prepared comprehensive environmental assessments that have been approved by the Danish Energy Agency. These assessments are designed to ensure that they take the necessary measures to protect nature and the marine environment in the area.
