Geotechnical investigations kick off at the 165 MW Lillebælt Syd wind farm site in Denmark, as reported on our website.
Geotechnical surveys for the Lillebælt Syd wind farm, located in the Little Belt strait between the islands of Als and Helnæs, have commenced in late July 2025. These surveys involve drilling and testing the seabed at each of the 11 planned turbine locations to assess ground conditions necessary for the wind farm’s foundations.
The project, owned by TotalEnergies, European Energy, and Danish utility SONFOR, has a planned capacity of 165 MW. The work follows initial test drilling in Jammerland Bay and is progressing as planned in the Little Belt area.
Meanwhile, the Jammerland Bugt wind farm, located in the Bay of Jammerland, has completed its geotechnical surveys in June. These surveys aimed to obtain detailed knowledge of the seabed conditions, with the surveys being conducted by a jack-up.
For the Lillebælt Syd wind farm, the surveys are necessary for the actual design and construction phase of the wind farm, as stated by Zhanar Dreisig, Asset Manager for TotalEnergies Denmark. The surveys mark the final phase of site investigations before making the final decision on the design.
Andreas Karhula Lauridsen, Vice President and Head of European Energy, has further highlighted that the geotechnical surveys at the Lillebælt Syd wind farm are crucial in characterizing the seabed soil and rock conditions. This information guides the engineering design of turbine foundations to ensure structural integrity and long-term stability in offshore conditions.
While no exact expected completion date for the geotechnical surveys at the Lillebælt Syd wind farm has been stated, it can be inferred that this work is scheduled over the summer months of 2025 to support the project’s next development phases after the construction permit was issued in November 2024.
In contrast, the Jammerland Bugt wind farm is not mentioned to be in the construction phase. However, the 240 MW wind farm, also owned by TotalEnergies and European Energy, has completed its geotechnical surveys. Construction of the wind farm is not mentioned in the given text.
Both wind farms, Lillebælt Syd and Jammerland Bugt, are owned by TotalEnergies, European Energy, and Danish utility company SONFOR. The commissioning of the Lillebælt Syd wind farm is scheduled for 2029, while the commissioning of the Jammerland Bugt wind farm is also scheduled for the same year.
Additional surveys related to the planning of the export cables for the Lillebælt Syd wind farm are expected to continue until the end of 2025, but no such information is given for the Jammerland Bugt wind farm.
The progress of these offshore wind farms in Denmark underscores the country's commitment to renewable energy and reducing carbon emissions. With the geotechnical surveys underway, both wind farms are moving closer to their planned operational dates, contributing to Denmark's ambitious renewable energy goals.

The geotechnical surveys at the Lillebælt Syd wind farm are crucial for the design and construction phase, guiding the engineering design of turbine foundations to ensure structural integrity and long-term stability. In the finance and technology sector, these surveys are key components in the upcoming development phases of the wind farm, due to be operational by 2029. On the other hand, the Jammerland Bugt wind farm has already completed its geotechnical surveys, but the exact progress on its financed design and industry-related activities are not specified in the given text.
