Propeller polishing is one of the most important marine services of maintenance, which restores the smoothness of surfaces and reduces the drag of the propeller, as well as enhances the efficiency of the vessel. Frequent polishing of propellers serves to improve fuel economy, power, reduce vibration and prolong the life of the propellers. The industry of marine polishing involves state-of-the-art underwater polishing methods that save optimal propeller operation and avoid corrosion, cavitation, and marine growth formation which is ideal in commercial ships, off-shore vessels and marine fleets.
