Full Hull Cleaning and Propeller Polishing with Final Condition Check at Kerry Siam Sea Port

MaxiDive completed full hull cleaning and propeller polishing at Kerry Siam Sea Port, including hull, appendage, propeller and rudder condition verification.

MaxiDive completed Full Hull Cleaning and Propeller Polishing for a commercial vessel at Kerry Siam Sea Port, Thailand. The underwater operation was carried out to clean the hull, polish the propeller and document the final underwater condition while the vessel remained afloat.

The work was performed under calm sea state conditions with approximately 3 meters of underwater visibility. MaxiDive’s commercial diving team used TG-7, GoPro-12, hydrophilic tools, hand tools and supporting equipment to complete the requested cleaning, inspection and documentation scope.

Marine support was arranged for the full hull cleaning and propeller polishing operation while the vessel remained afloat.

Full Hull Cleaning and Propeller Polishing: Service Scope

The requested underwater work focused on full hull cleaning and propeller polishing, followed by final condition verification of the main underwater areas.

The main work scope included:

• full hull cleaning;

• hull plating condition review;

• bulbous bow observation;

• sea chest grating inspection;

• appendage verification;

• discharge and drain plug checks;

• bilge keel condition review;

• anode condition documentation;

• propeller polishing;

• rope guard and seal assembly inspection;

• rudder assembly inspection;

• underwater photo/video documentation.

This type of service helps vessel operators maintain cleaner underwater surfaces, improve propeller surface condition and document key underwater components without immediate dry docking.

MaxiDive prepared underwater cleaning and documentation equipment for hull cleaning, propeller polishing and final condition verification.

Hull Plating Condition

The overall hull plating topcoat was reported in fair condition. The bulbous bow showed multiple abrasions consistent with contact from anchor chain.

No evidence of grounding was observed during the inspection. The overall hull plating weld seams were reported in fair condition.

These findings provide useful technical confirmation for the vessel’s maintenance record and help the technical team understand the condition of hull plating after the cleaning operation.

Appendage Condition Verification

The underwater inspection also covered appendages and related components. Both transducers were reported secure in place.

All sea chest gratings were secure and fastened in place. The overall discharges were reported in fair condition, and all visible drain plugs were securely in place.

All sections of the bilge keels were reported in normal profile. The overall anodes were secure and active, with approximately 20% depletion documented.

Appendage verification is an important part of underwater cleaning work because it helps confirm that key underwater fittings remain secure and free from visible operational concerns.

Propeller Polishing Result

The propeller assembly was inspected and polished as part of the underwater service scope. The seal assembly was reported free from signs of leakage, and the rope guard was in fair condition.

The propeller was polished to grade “A” according to Rubert Scale. All propeller blades were reported free from damage, and the boss cap was secure with keeper intact.

Polishing the propeller to Rubert “A” helps reduce surface roughness and supports better propeller surface condition for vessel operation.

Rudder Assembly Inspection

The rudder assembly was checked as part of the final underwater condition verification. No visual movement of the rudder was detected.

The overall anodes were secure, and the drain plug was secure in place. No sign of pitting was observed during the rudder inspection.

These findings provide useful technical documentation for future maintenance planning and help confirm the underwater condition after the cleaning and polishing operation.

Why Full Hull Cleaning and Propeller Polishing Matter

Marine growth on hull plating, appendages, sea chest gratings, rudder areas and propeller surfaces can increase drag, affect vessel performance and create additional maintenance requirements.

Full Hull Cleaning and Propeller Polishing help vessel operators:

• remove marine growth from underwater surfaces;

• maintain cleaner hull condition;

• improve propeller surface condition;

• reduce surface roughness on propeller blades;

• verify appendage and rudder condition;

• document anode and drain plug status;

• support maintenance planning without immediate dry docking.

Final condition verification is especially important because it provides the vessel’s technical team with documented evidence after the cleaning and polishing work is completed.
