Akrocean is a French marine renewable energy service company that provides environmental and metocean data collected at sea as a turnkey service for offshore monitoring and site assessment. Founded in 2017 with core partners GEPS Techno and Valemo and based in Guérande, it owns and operates a fleet of modular, self‑powered, passively stabilised buoys designed to host a wide range of floating LiDAR, RADAR, metocean and environmental sensors. Its target markets are offshore wind, other marine renewable energy applications and ocean sciences, where its systems are used to assess wind resources, characterise metocean conditions, establish site baselines and support environmental impact assessment and monitoring. Akrocean’s floating LiDAR technology is Stage 2 validated under the Carbon Trust roadmap by DNV, and its management system is certified to ISO 9001, ISO 14001 and ISO 45001.
The company’s service portfolio centres on three solutions: WINDSEA, a floating LiDAR turnkey service for wind resource assessment and metocean measurements; FLY’RSEA, a floating RADAR solution that can detect birds, bats, marine mammals and fish on a single system; and SEAOBS, a multiparameter offshore observatory that combines these and additional sensors to provide long‑term, multi-parameter environmental datasets. Akrocean provides 24/7 onshore supervision, early fault detection and rapid emergency response, and in 2022 reported 12 employees, €5.7 million in revenue, 7000 days of data collected worldwide and operations across 12 countries on three continents, with 43% of activity from export markets. It has delivered campaigns for offshore wind projects including a 12‑month metocean and floating LiDAR deployment for Energinet at Denmark’s 800MW Thor site and a four‑year Meteo‑France contract to deploy floating LiDARs in the English Channel, Atlantic and Mediterranean to de‑risk future French offshore wind tenders. Akrocean operates globally through a network of local maritime and logistics partners, opened a four‑person office in Ho Chi Minh City in 2022 to manage Asia‑Pacific projects and, as of 2026, is in exclusive negotiations to be acquired by CLS Group as part of a strategy to expand operational oceanography and marine renewable energy services.
