THE CHALLENGES

Underwater hull cleaning of vertical sides and flat bottom were found heavily fouled with various types of fouling, such as: sea grass (100%), barnacles (40%), noodle type marine growth (100%) and other type of marine growth (100%). Propeller was also found heavily fouled with sea grass, on the blades as well as on the boss cone. Sea chest gratings were found fully fouled with barnacles, mussels and sea grass. External cleaning of the gratings was successfully carried out. Propeller’s tail-shaft was found entangled with fishing-lines, which were cut off and removed. The underwater cleaning of flat bottom, vertical sides and curves was carried out by hydraulic brush kart system. The propeller polishing was carried out by 3M diamond disc pads.
