RWE has started soil investigations off the Danish west coast for the 1GW Thor offshore wind farm.
Up to three research vessels will acquire geotechnical data from the seabed approximately 22km from the port of Thorsminde.
The collected data is important for the fabrication and installation of the main components of the wind farm, RWE said.
The geological research vessel Fugro Scout (pictured) has already started geotechnical drilling and testing at the wind turbine locations.
The various information obtained will verify existing data and provide additional geotechnical parameters to assist with the detailed design and optimisation of the foundations for the offshore substation and wind turbines.
Two additional specialised vessels from Fugro will support the survey from mid-July onwards.
Normand Mermaid will be equipped to obtain key parameters to better understand the soil behaviour under turbines loading area.
Energy Scout will acquire key data to enable the design, installation and protection of the inter array cables and the main export cable that connects the offshore substation with the onshore grid.
Thermal conductivity tests will be carried out to determine the thermal properties of the soil in and around this area of development.
