Marine growth on a vessel’s underwater hull, propeller and appendages can affect hydrodynamic condition and vessel operation. Periodic underwater inspection helps determine the level and distribution of fouling before a cleaning plan is established.
Hull Cleaning
Underwater hull cleaning is performed to remove marine growth from selected underwater surfaces. The cleaning method and equipment should be selected according to the fouling condition, hull coating condition, vessel requirements and local operating restrictions.
Propeller Polishing
Propeller polishing focuses on removing surface deposits and marine growth from propeller blades. The work should be controlled carefully to avoid unnecessary damage to the blade surface.
Inspection Before and After Cleaning
Visual documentation before and after the work provides a useful record of the initial condition and completed cleaning. Areas such as the rudder, sea chest gratings and other appendages may also be inspected depending on the requested scope.
