What GREENOV-ITES does
GREENOV-ITES is a French maritime cleantech company founded in 2021 by Damien Demoor (formerly R&D strategist at a major French Naval Defense group) and headquartered in Vannes with an R&D center in Nantes. The company designs and commercializes hardware and software solutions to reduce human impact on marine ecosystems, anchored by its flagship SubSea Quieter (SSQ) system — a twice-patented, modular underwater noise and turbidity abatement platform based on a 3D air-inflated membrane that creates an acoustic impedance mismatch between water and air, achieving 10–45 dB noise reduction. SSQ is offered in configurations for coastal pile driving (1–2.5m piles), offshore jacket templates (2–4m), and offshore monopile foundations (6–12m), plus the Blue Shield wall system for harbors and rivers (up to 300m length).
The company's broader portfolio includes the Whale Alert mobile application (co-developed with IFAW and Conserve.IO for real-time cetacean sighting reporting and regulatory-zone notifications in Europe), the ShareDetect web platform, the Anti-Collision Alliance industry coalition, and an Innovation Lab pipeline covering Blue Silencer (construction-site acoustic containment), ContainHull@Sea (biofouling prevention), AWACS (hull-mounted cetacean warning systems), port-dredging impact reduction, and the MALO acoustic metamaterials project for retrofitting operating offshore wind turbines.
GREENOV generates revenue through sale and rental of SSQ hardware systems, professional services for deployment and integration, and non-dilutive European and French R&D grants (EIC, LIFE, Horizon Europe, ADEME, Bpifrance, Région Pays de la Loire). Its go-to-market is enterprise field sales targeting offshore wind developers and operators (Chantiers de l'Atlantique, EDF Renewables, Equinor, Enbridge, Atlantic Shores, Éoliennes en mer Dieppe Le Tréport), transmission system operators (RTE), and maritime construction firms (Bouygues Travaux publics, Heerema), complemented by event-driven industry-conference presence and community-led consortium participation (LIFE SeaDetect, SafeNav, Quiet-Oceans, CAP SSQ industrial cluster).

GREENOV-ITES product offering
Product offeringCore offering
GREENOV-ITES sells the twice-patented SubSea Quieter underwater noise and turbidity abatement system, a modular 3D membrane product family used around pile driving operations and harbor works for offshore wind, coastal, and port infrastructure customers. The company also distributes Whale Alert, a collaborative mobile application developed with IFAW and Conserve.IO for real-time cetacean sighting reporting and ship-strike avoidance, and is commercializing additional maritime cleantech solutions (ShareDetect, Blue Silencer, ContainHull@Sea, AWACS, MALO acoustic metamaterials) from its Innovation Lab.
Product overview
GREENOV-ITES offers a portfolio of CleanTech solutions for maritime ecosystem protection. The core product SubSea Quieter® is a modular underwater noise and turbidity abatement system available in multiple variants: Pile Driving versions for coastal works, offshore Jacket, and offshore Monopile foundations, plus Blue Shield for harbor/river zone containment. Whale Alert is a collaborative mobile app (with IFAW and Conserve.IO) for real-time cetacean sighting reports and collision prevention. ShareDetect is a web platform for cetacean detection. The Innovation Lab develops emerging technologies including Blue Silencer for construction noise, ContainHull@Sea for biofouling prevention, AWACS acoustic warning systems for ships, port dredging impact reduction, and Acoustic Metamaterials for offshore wind turbine noise abatement. The Anti-Collision Alliance coordinates industry actors committed to reducing vessel-cetacean collisions.

Products and services
- SubSea Quieter Pile Driving System A twice-patented modular underwater noise and turbidity abatement system for pile driving operations in coastal and offshore conditions. Available in coastal, offshore jacket, and monopile configurations supporting 1–12 m diameter piles, deployable in under 45 minutes, reusable, and eco-designed. Delivers 10–45 dB of underwater noise reduction across 60–500 Hz bands, validated over 150 deployment cycles at Saint-Nazaire. Targeted at offshore wind developers, jacket and monopile foundation installers, and maritime construction companies.
- SubSea Quieter Blue Shield A wall system made of two layers of inflated membrane providing combined noise abatement and turbidity containment for zone containment in harbors and rivers. Lengths up to 300m with automatic inflation/deflation management per row of panels using only two compressors. Designed for port authorities and harbor construction projects needing both acoustic mitigation and turbidity control in confined waters.
- Whale Alert A collaborative citizen-science mobile application co-developed with IFAW and Conserve.IO to prevent collisions between ships and big cetaceans through real-time sighting reports and regulatory-zone notifications. Works in both online and offline modes and includes a species identification guide, behavioural advice, and a trusted-observer verification system. Targeted at commercial and recreational mariners, marine scientists, NGOs, and conservation programs in MSR, SMA, DMA, ATBA, RR, and MPA zones.
- ShareDetect A web application for detecting the presence of cetaceans in an area by aggregating collaborative data, supporting marine conservation efforts. Targets conservation programs and marine protected area managers needing broader sighting coverage.
- Blue Silencer An acoustic containment system for construction sites using water-filled membrane barriers to limit noise nuisance to local residents. Marketed as providing superior acoustic reduction versus market alternatives. Targets coastal construction companies and developers facing local community opposition to airborne and structure-borne noise.
- ContainHull@Sea A CleanTech solution for ship hull containment at dockside designed to combat biofouling by combining three physicochemical parameters: absence of light, water hypoxia, and fresh water injection. Targets ship operators, ports, and shipyards seeking non-toxic biofouling control alternatives.
- AWACS (Approaching Vessel Warning Device for Cetaceans) An acoustic warning device placed under ship hulls to alert cetaceans of approaching vessels. Frequencies and acoustic wave orientation are optimised to alert cetaceans while minimising additional underwater noise pollution. Targets commercial shipping operators and ferry companies seeking an in-vessel collision-avoidance augmentation alongside Whale Alert.
- Port Dredging Impact Reduction System A system of acoustic and luminous spotters designed to reduce accidental catch of fish and elvers during dredging operations, using an acoustic scarecrow combined with strobes at the suction head. Targets port authorities, dredging contractors, and environmental agencies seeking to mitigate ecological impact of dredging campaigns.
- Acoustic Metamaterials (MALO) Novel acoustic metamaterials engineered with internal structures that create band gaps where vibrations cannot propagate, designed for offshore wind turbine noise abatement. The technology uses band-gap engineering to block vibratory wave propagation and is intended to be retrofitted on existing turbines, mitigating the in-operation noise footprint of offshore wind. Targets offshore wind operators and OEMs seeking in-operation (not just construction-phase) noise control.
Quantifiable outcome
- Underwater noise reduction of 10-45 dB depending on frequencies (60 Hz: 12-14 dB, 100 Hz: 12-15 dB, 200 Hz: 10-14 dB, 500 Hz: 18-21 dB)
