Underwater inspections are a critical component of ship husbandry, providing a clear view of a vessel’s condition below the waterline without dry docking. Performed by certified commercial divers or ROVs, these inspections support regulatory compliance, preventative maintenance, and operational safety—often required by classification societies, insurers, and port authorities.
Basic condition check of hull, propellers, rudders, and underwater fittings
Identifies marine growth, coating wear, damage, corrosion, or missing components
A more detailed inspection than GVI
Includes photographic or video documentation for in-depth reporting and analysis
Approved by classification societies (e.g., ABS, DNV, Lloyd’s Register)
Allows class certification without taking the vessel out of the water
Must be pre-approved and carried out under strict standards
Utilizes high-definition underwater cameras
Enables real-time viewing by clients and surveyors
Ideal for regulatory documentation and third-party assessments
Measures the thickness of steel plates or hull materials
Essential for monitoring corrosion and structural wear over time
Post-incident assessments following groundings, collisions, or structural concerns
Detects cracks, breaches, denting, or hull deformation
Hull plating and protective coatings
Propellers and shafts for wear or damage
Rudder and pintles
Sea chests, gratings, and intakes
Thruster tunnels and gratings
Sacrificial and impressed current anodes
Weld seams and hull penetrations
Mooring and anchoring systems (where accessible)
