Soil analysis puts brakes on offshore Denmark wind farm

The Danish Energy Agency (DEA) has put on hold the tender for the Hesselø wind farm offshore eastern Denmark, pending further analysis of results from a preliminary site investigation.

Soft clay formations have come to light, notably in the upper 20-30-metre (65.6-98.4-foot) portion below the seabed, over large parts of the area selected for the wind farm.

Results suggest site conditions are less favourable than initially specified in the fine screening report, potentially creating technical challenges with the installation.

External consultants are undertaking further laboratory analyses to assess the strength properties of top soil in the area. Once this work has finished during the fall, the DEA expects to discuss the consequences with potential bidders.
