High Precision Underwater Propeller Polishing

At Leos Maritime, we deliver high precision underwater propeller polishing services designed to maximize your vessel's performance, reduce fuel consumption and minimize operational costs. A smooth, well maintained propeller is critical for efficient propulsion and our expert team ensures your propeller blades operate at peak hydrodynamic efficiency without the need for dry docking.

Key Advantages Of Regular Propeller Polishing

Key Advantages Of Regular Propeller Polishing

Over time, propeller surfaces accumulate marine growth, scale and micro pitting, creating drag that impacts vessel speed, fuel efficiency and emissions.

  • Fuel savings: Regular polishing can reduce fuel consumption by 3 to 8%.
  • Lower emissions: Optimized propulsion cuts greenhouse gas emissions and supports IMO decarbonization goals.
  • Reduced vibration and noise: Smoother blades mean quieter operations and less stress on propulsion systems.
  • Extended propeller lifespan: Prevents corrosion and surface damage, protecting your asset investment.

Our Propeller Polishing Process

  • Initial inspection uses divers or ROVs to assess propeller condition.
  • Rough polishing removes scale, heavy fouling and surface damage.
  • Intermediate polishing refines the blade surface to reduce roughness.
  • Fine polishing (Class A finish) achieves a mirror smooth surface (~0.4 µm Ra), ensuring maximum efficiency.
  • Performance reporting delivers detailed reports with before/after images and efficiency recommendations.
