This important function can be undertaken through the use of either ROV’s (Remote Observation Vehcile) which is a diverless operation OR through the deployment of qualified divers with hand-held video and still-camera. Both methods of observation can be relayed to the surface in real time on closed circuit TV monitors.
Propeller Polishing and repairs
Dubina Engenering use the Scotchbrite 3M system with propeller polish pads in grain 3 and 5 to achieve a high quality mirror like finish (where propeller casting allows). Before and after photos of our underwater polishing service are always provided. Our clients consistently advise us after service of the immediate recognisable fuel savings as a result of our underwater propeller service.
