Rov Hull Inspection Supplier - Underwater Hull Inspection

ROV hull inspection involves using remotely operated vehicles to examine a ship's submerged structure for damage or fouling. Underwater hull inspection assesses the condition of the vessel's exterior below the waterline, including propellers and rudders. These inspections help ensure safety, compliance, and operational efficiency without dry-docking.

Size: Typically 0.5m to 2m in length, depending on the model and application.

Grade: Marine-grade materials, often certified for underwater use (e.g., ISO 12215 or ABS standards).

Viscosity: Operates in water with dynamic viscosity of ~0.001 Pa·s (freshwater) to ~0.0013 Pa·s (seawater).

Buoyancy: Neutral or slightly positive buoyancy, adjustable with ballast or floats.

Material: Corrosion-resistant alloys (e.g., aluminum, stainless steel) or composites (e.g., fiberglass, carbon fiber).

Thrusters: Typically 4-6 thrusters with 5-50 kgf thrust capacity.

Depth Rating: 100m to 3000m, depending on design.

Sensors: HD cameras, sonar (multibeam or imaging), and optional NDT sensors (ultrasonic thickness gauges).

Power: 24V to 48V DC, with 1-10 kWh battery capacity or tethered power supply.
