Underwater Operations & Maintenance
Hull cleaning, propeller polishing, UWILD inspections, sea chest servicing, and emergency underwater repairs to eliminate unnecessary dry-docking.
Our commercial diving teams deliver class-standard in-water surveys and interventions that keep vessels trading without the cost and delay of dry-docking. Each dive is executed under a formal dive plan and Job Safety Analysis agreed with the vessel's Master, with continuous topside supervision and full communications to the diver.
Scope typically covers systematic inspection of the entire underwater hull envelope — port and starboard shell plating, bilge keels, bulbous bow and flat bottom — together with the rudder assembly, propeller blades and boss, and all sea chest gratings. Fouling coverage, coating condition, anode wastage and structural anomalies are documented in real time using high-resolution underwater stills and continuous video, and compiled into a formal report with time-stamped imagery for Owners and attending class surveyor.
For cleaning operations we use rotary brush equipment calibrated to preserve the vessel's anti-fouling paint system, restoring hydrodynamic performance and improving fuel economy without damage to the coating. Before/after video is issued as verification of the delivered condition.
