Propeller Polishing & Cleaning
The propeller is the uniform of every ship, for it is that article which enables her to make progress through the fluid sea. The best designed, shiniest propeller doesn’t stay shiny for long.
Propeller fouling, corrosion and roughness are as well among the effect of always sailing in seawater. Within months, the shiny bronze or nickel-aluminium-bronze blades can lose their gleam and end up slimed, barnacled and pitted by small rough patches.
The effect may not be visible from deck, but down in the performance logs, the Chief Engineer will notice a small rise in fuel consumption, and the Master may observe a drop in service speed. A fouled propeller makes the main engine work harder, wastes fuel, and increases CO₂ emissions.
That’s why propeller polishing is one of the most cost-effective maintenance jobs in shipping.
Propeller polishing may look like a small maintenance job, but for a ship operator it’s a big-ticket efficiency booster. A smooth, polished propeller means:
Fuel Efficiency: Studies show that even a lightly fouled propeller can increase fuel consumption by 5–10%. On a VLCC or Capesize bulk carrier, that means several tons of extra fuel daily.
Improved Speed: Ships maintain charter party speed without overloading the engine.
Vibration Reduction: Smooth propellers eliminate cavitation and vibration that transfers to the rest of your boat.
Reduced Emissions: Lower fuel burned = reduced CO₂, NOₓ & SOₓ.
Life of the Propeller: Less wear, pitting and cavitation erosion equals longer service life.
Divers use hydraulic polishing machines fitted with abrasive pads/discs.
Usually performed in graded stages: Coarse → Medium → Fine finish.
Achieves final smoothness of Ra < 0.8 µm (international standard).
Immediate performance improvement without dry docking.
