Underwater Services
Cleaner hull. Better burn. Certified by class.
What we deliver
Sea Light International operates a class-approved commercial diving team providing underwater hull cleaning, propeller polishing, in-water surveys (IWS), UWILD and emergency underwater repairs.
Hull fouling costs vessels up to 20% additional fuel burn. Our brush-cart hull cleaning restores hydrodynamic performance and is typically completed alongside within 6–12 hours depending on vessel size. Propeller polishing to MEP surface standard delivers measurable fuel savings within days.
Divers are qualified to IMCA standards and hold offshore medical certificates. All operations are attended by a Diving Supervisor and support crew, with full risk assessment and permit-to-work documentation.
