Underwater Hull Cleaning Services involve removing marine growth, algae, and debris from a ship's submerged surfaces. This process improves fuel efficiency, reduces drag, and prevents hull damage. Specialized divers or robotic systems are used to perform the cleaning without dry-docking the vessel.

Underwater Hull Cleaning Services typically involve robotic or diver-operated systems designed to remove biofouling, algae, and marine growth from ship hulls. Key specifications include:

Size: Cleaning systems range from compact handheld devices (30–50 cm) to larger robotic units (1–3 meters).

Grade: High-grade stainless steel (316L) or corrosion-resistant alloys for durability in seawater.

Viscosity: Cleaning brushes or water jets operate at pressures of 100–500 bar, with water flow rates of 20–200 liters per minute.

Buoyancy: Neutral or slightly negative buoyancy for stability, often achieved with syntactic foam or buoyancy aids.

Material: Brushes use nylon, polypropylene, or stainless steel bristles; robotic systems feature waterproof housings (polyurethane or aluminum).

Additional Properties: Systems may include thrusters (10–50 kg thrust), cameras (1080p/4K), and ultrasonic sensors for navigation.
