PROPELLER POLISHING

One of our specialization requested by the most Owners / Managers are the underwater propeller polishing grade "A" to Rubert Scale together with a proper hydrodynamic draw.

These operations are carried out using our hydraulic hand brushes operated revolving machines which rotate at high speed rpm which exclusively eliminate the organic biofouling material adhered to the blades and appendages.

The hand brushes machine´s revolving heads are fitted with abrasives diamond pads discs "3M" which are graded coarse of blade surfaces. The smoothness measurement is achieved by the Rubert Gauge Comparator Scale.

The aims of propeller polishing are to keep propulsive friction to a minimum and maximize thrust. A propeller polished to high standard will conserve fuel and increase vessel´s speed, thus giving the vessel a faster turnaround and reducing operating cost.
