The official Oléron 1 project portal states that a dedicated "campagne géotechnique" (geotechnical campaign) was carried out for the Oléron 1 offshore wind project from July to September 2023, within the broader 2022–2025 knowledge studies programme for the Sud-Atlantique area. This timeframe indicates that the marine geotechnical survey work for the project area was completed by September 2023. The campaign is listed alongside other offshore measurement and seabed characterisation activities on the site, confirming it as a core site-investigation milestone for Oléron 1.
