In Panama Aquadiver team divers for Hull, cleaning use Special Twin Hydraulic Brushes to remove any kind of marine grows from vessels, have used special brushes in contact with the hull surface removing all fouling layer to remove fouling. The material of the brush can be different and depends on marine grow attached
 Different kind of brushes materials is also used on the different hull as nylon or
plastic, Stanley steel brushes are an example
Other methods of removal include: rotating  brushes that create centrifugal force
over the hull surface without touching it, high-pressure with hydraulic power packs powered
These methods are intended to reduce the friction effects of marine grow on antifouling coatings,

• UW FULL CLEANING: The term full cleaning refers to the removal of fouling from the entire underwater hull shell plates structure, additional areas, including propeller and shafts, overboard valves 
• INTERIM UW CLEANING: The term interim cleaning refers to the removal of fouling from the propeller, shafts, and rudders. Cleaning of other submerged ship systems may occur during this
gap. Interim cleanings are planned scheduled for all vessel between regular full cleanings to take advantage of fuel savings, Possible average of 50% represent fuel savings benefit of cleaning an entire hull due to

the cleaning of propeller blades.
• PARTIAL UW CLEANING – The term partial cleaning means to any cleaning where only specific areas of the ship vertical sides, rudders, sonar, bilge keels
