EverClean
Autonomous hull maintenance for improved vessel efficiency
EverClean is a robotic hull grooming and inspection solution designed to maintain vessel performance through frequent, proactive removal of early-stage biofouling. Available as a subscription-based service or a self-hosted solution, EverClean enables routine hull maintenance without disrupting vessel or port operations.
The subscription service provides scheduled in-water grooming during port visits, including alongside cargo operations. Alternatively, the self-hosted solution allows robotic systems to be stationed onboard vessels or at dockside facilities, with cleaning operations conducted remotely from Greensea IQ’s Remote Operations Center using Over-The-Horizon (OTH) technology.
Built on more than 20 years of underwater autonomy expertise, EverClean uses a modular robotic platform equipped with coating-safe, soft nylon brushes to remove early-stage biofouling before it increases hydrodynamic drag. By maintaining hulls in a condition comparable to freshly dry-docked vessels, the system helps reduce fuel consumption, limit the transfer of invasive species, and improve operational efficiency.
EverClean follows a comprehensive Clean, Collect, Analyze, Report, and Inform process, capturing continuous video and positional data during every grooming operation. This information is integrated into the EverClean IQ dashboard, enabling operators to monitor coating conditions, identify fouling trends, and review before-and-after footage.
With biofouling potentially increasing vessel emissions by 25%, EverClean can deliver fuel savings of up to 22%, while supporting improved Carbon Intensity Indicator (CII) ratings and more informed fleet maintenance decisions.
