One of the main causes of the increase in fuel consumption and the decrease in the efficiency of the ship, is the prolific accumulation or marine incrustations in the hull thereof. An accumulation of marine incrustations in the hull is equivalent to a greater drag or friction with the water,…
Rupert Scale
The Rupert scale is the worldwide accepted standard for measuring and recording the roughness of the propeller blade. The Rupert Scale ‘A’ grade, which roughly equals a surface roughness of .65 microns, is apparently the highest quality finish that can be achieved by polishing and reconditioning the propeller blades. Seven…
Polishing of helices. Spend less fuel!
It is inevitable that the performance and fuel efficiency of any vessel will decrease over time, due to the wear of its engines or hydraulic parts. There are several factors that can accelerate this wear, being the rugosity of the propeller a common and important factor. As the propeller fulfills…
