EverClean is Greensea IQ’s dual-use underwater hull cleaning and inspection solution built on 20 years of proven autonomy. Whether delivered as a subscription service in established ports or deployed as a self-hosted capability for fleet operations worldwide, EverClean keeps hulls clean, data flowing, and vessels ready.

Two delivery models. One mission: continuous hull performance and operational advantage.

Why EverClean?

  1. Lower Fuel Consumption & Emissions - Proactive microfouling removal maintains hydrodynamic efficiency, reducing drag and improving vessel performance.
  2. Smarter Maintenance Decisions - Integrated inspection capability and persistent hull data support predictive maintenance, security assessments, and pre-dry dock planning.
  3. Reduced Risk to Coatings - Coating-safe grooming avoids the damage associated with abrasive, reactive cleaning methods.

Lower Fuel Consumption & Emissions

Even thin layers of microfouling increase drag and force engines to work harder. EverClean removes biofilm early, maintaining a smooth hydrodynamic surface that supports optimal vessel performance.

The result is measurable efficiency gains, reduced fuel burn, and lower emissions — without waiting for fouling to become a costly problem.

Smarter Maintenance Decisions

EverClean pairs proactive grooming with close visual inspection and persistent hull data. Instead of relying on assumptions or dry dock surprises, operators gain real visibility below the waterline.

That insight enables predictive maintenance planning, more accurate repair scopes, and better timing of coating interventions.

Reduced Risk to Coatings

Reactive, abrasive cleaning methods can compromise coating systems and accelerate degradation. EverClean is designed to remove microfouling early using coating-compatible methods that preserve surface integrity.

By protecting coatings, operators extend performance life, reduce repaint frequency, and avoid unnecessary dry dock costs.

Frequently asked questions

Here are just a few of the most common questions and answers

What is EverClean and how is it different from traditional hull cleaning?

EverClean is a proactive underwater hull cleaning and inspection system developed by Greensea IQ. Unlike traditional reactive cleaning methods that remove heavy fouling with abrasive tools, EverClean removes microfouling early using coating-safe grooming technology.

By maintaining a consistently clean hull, vessels preserve hydrodynamic performance, reduce fuel consumption, and avoid the coating damage often associated with aggressive, last-minute cleaning.

Is EverClean safe for hull coatings?

Yes. EverClean was designed specifically to preserve coating integrity.

Reactive cleaning methods that target macrofouling often rely on aggressive brushes or scraping, which can damage protective coatings and shorten coating life. EverClean removes biofilm at the early stage, using controlled, coating-compatible methods that maintain both surface smoothness and coating performance.

What types of vessels can use EverClean?

EverClean is compatible with a wide range of hull types and materials, including steel and coated composite surfaces.

The system’s non-magnetic design and advanced mobility platform allow it to operate on surface vessels and submarines, making it suitable for commercial fleets and defense applications alike.

What is the difference between EverClean Subscription and Self-Hosted EverClean?

EverClean is available in two delivery models:

  • Subscription – Available in Florida, Texas, and Caribbean ports. Greensea IQ service teams perform scheduled hull grooming and inspection as part of a recurring performance program. This is a recurring monthly fee.
  • Self-Hosted – Designed for defense fleets and commercial operators outside service ports. EverClean robots are purchased and training is provided. Over-the-horizon support from Greensea IQ's EverClean service team is available.

Both models use the same proven EverClean technology platform.

Does EverClean provide inspection data as well as cleaning?

Yes. EverClean integrates close visual inspection capability to support condition assessments, coating evaluation, and security monitoring below the waterline.

Persistent data collection enables predictive maintenance planning, pre-dry dock assessments, and improved decision-making around hull condition and performance.

How does EverClean impact fuel consumption and emissions?

Even thin layers of microfouling increase hull roughness and hydrodynamic drag. By removing biofilm early and maintaining a consistently smooth surface, EverClean helps vessels maintain optimal performance.

Operators typically experience improved fuel efficiency (a range of 5-20%) and reduced emissions.
