PROPELLER DIAMOND SUPER POLISHING
According to International Research Studies such as the International Council on Clean Transportation (ICCT) and the Global Maritime Energy Efficiency Partnerships (GloMEEP), propeller polishing can reduce gas emissions by 2% – 5% and fuel consumption by 3% – 4 %.
Propeller polishing is equally important for the maintenance of the propeller since it contributes to the prevention of cavitation erosion which can be avoided by regular polishing of the propeller. It is recommended to run twice a year. This has been found to have the optimal balance between cost and effect.
For propeller polishing our company uses hydraulic driven polishers fitted with 3M industrial diamond flexible discs of different density & Scotch Brite soft pads for the conditioning & finishing thus attaining results of Rubert Scale grade “A”.
This finish can be achieved on propellers of reasonable condition, free from defects such as cavitation pitting, dezincification or mechanical damage.
