The Future of Maritime Maintenance
Autonomous subsea hull cleaning that reduces operational costs, eliminates dry-dock downtime, and ensures peak vessel efficiency—24/7, in any sea state.
Cutting Through the Cost of Biofouling
Global shipping faces a silent drain on profitability: biofouling. Unmanaged marine growth on vessel hulls increases fuel consumption by 35-40%, costing operators millions annually while forcing ships into costly dry-dock cycles that halt revenue-generating operations.
Traditional cleaning like dry-dock requires weeks of downtime and massive operational losses, while commercial divers deliver inconsistent results with significant safety risks and weather dependencies.
R2’s solutions operate while vessels are in service—no dry-dock required, no schedule disruptions, no revenue loss. Autonomous cleaning happens during port calls or at anchor, keeping hulls at optimal hydrodynamic efficiency without forcing ships out of operation.
Economic Impact
- +35-40% fuel consumption increase from biofouling
- $1.76M annual fuel loss (20,000 TEU container ship)
- $45,000 daily operational loss from speed reduction
Environmental Mandate
- 2030 IMO Target: 20% GHG emission reduction vs. 2008 levels
- 2040 IMO Target: 70% GHG emission reduction vs. 2008 levels
- 2050 IMO Target: Net-Zero emissions
How R2 Keeps Your Vessels In Service
Negative Pressure Adhesion System
High-speed rotation generates localised negative pressure, ensuring the robot remains securely coupled to the hull surface. The system works on all hull materials (steel, aluminum, composites) with high adaptation to complex hull curvatures (minimum radius: 1m) and superior performance in high-surge environments.
Cavitation Jet Cleaning Technology
Localised pressure drops create cavitation bubbles that generate shockwaves (6-24 times the initial pressure), effectively stripping biofouling without damaging protective coatings. The system delivers cleaning speeds exceeding 800m²/h while preserving coating integrity and extending hull life.
Autonomous Navigation & Path Planning
AI-driven algorithms optimise cleaning trajectories to maximise operational efficiency and ensure 100% surface coverage with zero “blind spots.”
