Investigations at the proposed project site have revealed soft clay formations, particularly in the 20-30 metres immediately below the seabed. The apparently less favourable conditions may lead to technical challenges with installation, the agency added.
Consultants are now undertaking further laboratory analyses, in order to fully assess the properties of the top soil in the area. These are due for completion in the autumn of 2021.
The Danish Energy Agency would then reopen a discussion with the wind power industry, as to what the results mean and how the tender process should proceed.
It had recently announced its intention to run a contract for difference-style tender for the Hesselø project and was due to provide a final timeline for the auction later this year.
