Underwater ship propeller cleaning involves removing marine growth, barnacles, and debris from propellers without dry-docking. This process improves fuel efficiency, reduces drag, and enhances vessel performance. It is typically performed by divers or remotely operated vehicles (ROVs) using specialized tools.

Size: Typically ranges from 100 mm to 500 mm in diameter, depending on the propeller size.

Grade: Industrial-grade cleaning tools, often classified by abrasiveness (e.g., mild, medium, aggressive).

Viscosity: N/A (tool-based, not fluid-dependent).

Buoyancy: Neutral to slightly negative buoyancy for underwater stability.

Material: Stainless steel, carbon fiber, or composite materials for durability and corrosion resistance.

Cleaning Method: Mechanical brushing, water jets, or ultrasonic technology.

Power Source: Hydraulic, electric, or pneumatic systems.

Operating Depth: Up to 50 meters for most standard systems.

Compatibility: Designed for use on bronze, stainless steel, or nickel-aluminum-bronze propellers.

Environmental Impact: Eco-friendly, non-toxic cleaning solutions may be used.
