Propeller Polishing

A smooth, polished propeller will increase your vessel’s efficiency and improve fuel consumption

Two advantages of polishing underwater are:

  • Water cooled/lubricated abrasive pads are far faster to use than air-cooled abrasives and ensure a higher quality finish

  • The machine creates a suction pressure on the blade surface and lies flat, ensuring a smooth, even finish to your prop

  • Hull cleaning using hydraulically driven two and three brush units

  • Changing cathodic protection

  • Provision of coffee dams for internal repair

Dive Vessel & Tug Boat
