Ship propeller polishing removes marine growth from the surface of propeller blades which may significantly reduce fuel consumption. Underwater propeller polishing enhances reliability and extends maintenance cycles of vessels. Propeller polishing is permissible in Australian ports and harbours providing the requirements of the ANZECC Code of Practice is adhered to.
The process is typically conducted within a 12 hour period while the vessel is at berth loading or discharging. Research has shown that the adoption of a propeller polishing routine generates significant savings. For example, it is typically believed that proper propeller maintenance should result in fuel savings per year of at least 10% depending on vessel activity and extent of layups.
