Underwater Services for Vessels in Vietnam
Underwater inspection and hull cleaning can directly affect vessel performance, fuel consumption, class requirements, charterer confidence, port clearance and drydock planning. Marine growth, fouled propellers, blocked sea chests, damaged rudder areas, draft mark visibility issues or suspected underwater damage may require quick diver attendance during port stay or anchorage.
SVC Marine coordinates underwater inspection and hull cleaning support at major Vietnamese ports and anchorage areas, subject to port permission, weather, diving safety, vessel condition, class requirement and local availability.
Our support is suitable for:
- Vessels requiring underwater inspection during port stay
- Hull cleaning before voyage, charter or inspection
- Propeller polishing to improve vessel performance
- Sea chest and grid cleaning
- Draft mark inspection and cleaning
- Rudder, propeller and thruster visual inspection
- Class-related underwater survey coordination
- Underwater damage check after grounding, contact or suspected impact
- Drydock planning and pre-docking condition check
Our Underwater Inspection and Hull Cleaning Scope

- Propeller and rudder area inspection
- Sea chest and grid inspection
- Bilge keel and hull appendage inspection

3. Propeller Polishing
Propeller fouling and roughness can affect vessel performance. Propeller polishing may help improve propulsion efficiency and reduce performance loss, depending on vessel condition and operational profile.
- Propeller blade cleaning
- Propeller polishing coordination
- Photo/video record before and after work
- Rudder and propeller area visual check
- Coordination with vessel crew and diving team

- Diver attendance coordination
- Photo/video evidence collection
- Communication with class surveyor where required

Underwater Damage Inspection
After suspected grounding, contact, floating object impact, propeller vibration, steering issue or unusual machinery alarm, underwater inspection may be required to check visible damage before the vessel continues operation.
SVC Marine can coordinate underwater inspection for visible condition checking of:
- Hull bottom and side shell areas
- Propeller blades
- Rudder and rudder stock area
- Bilge keel
- Sea chest and grids
- Thruster tunnel and tunnel grids where applicable
- Draft marks and underwater fittings
Any serious structural, class-critical or safety-related finding should be reviewed by the vessel’s manager, class society, flag administration, insurer and relevant authorities.
Class, Owner and Technical Reporting
Underwater work often needs clear reporting. Owners and managers need photos, videos, work summary, diver comments and practical recommendations to decide whether the vessel can sail, needs further repair or should proceed to drydock.
Depending on the assignment, our report support may include:
- Service attendance summary
- Underwater photo and video records where available
- Before-and-after cleaning evidence
- Observed defect or fouling summary
- Diver/service provider report collection
- Class or surveyor follow-up support where required
- Recommended next action for owner or manager
Underwater Services During Ship Repair or Drydock Planning
Underwater inspection is often linked to ship repair, drydock planning, pre-purchase inspection or vessel delivery. A short underwater inspection before docking or purchase can help identify visible damage, marine growth, propeller condition and repair priorities.
SVC Marine can combine underwater service coordination with:
