Greece boasts some of Europe’s clearest waters ideal for conducting in-water hull surveys, inspections, and cleaning with class attendance.
At Karval Shipping Agency, we ensure every inspection is thorough, compliant, and maintained to the highest standards.

⚓Regulatory Confidence & Class Compliant
Our dives meet Classification In-Water Survey (IWS) standards with live video monitoring and class surveyor attendance, ensuring full compliance and peace of mind.
⚓Comprehensive Underwater Services
From inspections and pre-purchase reports to hull cleaning, propeller polishing, welding, plate repairs, and tail-shaft or rudder measurements, our ABS, DNV, BV, LR, RINA & NK certified divers cover all underwater needs across Greece.
⚓Optimized Vessel Performance & Cost Savings
Clean hulls reduce biofouling, boosting speed and fuel efficiency, and lowering emissions by up to 40%, while extending coating life.
⚓Advanced Equipment & Safety Practices
Our operations rely on motorboats, state-of-the-art diving cleaning tools, robots, and fully approved welding procedures (WPQR), all under strict safety protocols.
⚓Rapid, Reliable Service
Inspections, cleanings, and propeller work are often completed within a day, even for large vessels like Suezmax tankers, across multiple Greek anchorages.

At Karval Shipping Agency, underwater hull inspection and cleaning isn’t just a service; it’s a specialty. With certified commercial divers, class approvals, and cutting-edge equipment, we provide shipowners with reliable, in-water solutions that meet regulatory demands and improve vessel performance. Whether it’s routine cleaning to boost fuel efficiency or class-approved surveys with video documentation, we deliver fast, professional results across all major Greek ports and anchorages.

Even a thin layer of biofouling on a tanker’s hull can increase fuel consumption by up to 15%.
For a vessel burning 50 MT/day, that’s an extra 7.5 MT daily, costing $3,000–$4,000 more per day at today’s bunker prices. Multiply that over weeks at sea, and the costs are staggering.
✅ Regular hull inspections help fleet managers:
Detect fouling early, before it impacts performance
Reduce bunker costs & lower CO₂ emissions
Stay compliant with class & IMO efficiency standards.
