The propeller efficiency deteriorates in time due to the increasing surface roughness and also with the growth of marine fouling. The propeller roughness significantly affects ships such as high fuel consumption, low speed and less power performance.
Propeller polishing is an economic and cost effective method to maintain the good performance of vessel. After polishing, the surface condition will be checked using the Rubert Comparator Scale which consists of 6 specimens reflect exact replicas of the surface roughness of propeller blades.
