ELWAVE deployed its new active electrics sensor Octopulse in September 2023 for an UXO survey on EFGL (Eoliennes Flottantes du Golfe du Lion) floating offshore wind farm site. This survey was carried out with ELWAVE’s Octopulse sensor based on its patented CEDAR® technology providing accurate and high-sensitivity electrical impedance cartography of the area surrounding the wind farm.

ELWAVE’s contract includes the integration of its sensor onboard an observation-class ROV, as well as data acquisition, analysis and mapping of electrical anomalies. The success of the mission will contribute to de-risking the installation of the EFGL floating offshore wind turbines due to be installed in 2024.

Mr. Pierre TUFFIGO, ELWAVE’s Chief Executive Officer, stated “We are very proud to have successfully completed this first survey with our world-class electromagnetics Octopulse sensor for this important renewable energy project. EFGL stakeholders are very satisfied with the results and the reliability of the sensor during the survey. The campaign has validated the effectiveness of our technology for marine UXO surveys and seabed mapping and we are very much looking forward to the ongoing commercial deployment of our Octopulse sensor”.
