JOINT PACIFIC OCEAN UNDERWATER SERVICES PRIVATE LIMITED has a new approach to propeller cleaning.
The traditional approach in the industry is to let the propeller get fouled, build up a large amount of calcareous growth and then polish it in the water once or twice a year or in dry-dock. This polishing is done with a grinding disk that can be quite damaging to the propeller, causing a substantial amount of metal to be removed from the propeller itself. This can alter the shape and efficiency, cause roughness and increase rather than reduce friction. It can also be a source of marine pollution which is a problem in several ports.
JOINT PACIFIC OCEAN UNDERWATER SERVICES PRIVATE LIMITED’s method of more regular, lighter cleaning of the propeller using a different tool to a grinding disk and catching the propeller before a calcareous layer builds up is the optimum approach to propeller cleaning.
Doing it right and done regularly, can result in better speed and/or even more fuel savings. This far outweighs the cost of the propeller cleaning itself. If a propeller is maintained regularly, the cleaning is relatively light and quick. No material is ground away, which is best for the propeller and the environment.
Propeller surface roughness directly affects propeller efficiency, and a higher propeller efficiency equals lower fuel consumption. The propeller is kept in an ultra-smooth condition and that’s where the real fuel savings can be achieved. This finish can only be accomplished through in-water propeller cleaning.
