Tugboat underwater inspection report in Vietnam

Our divers examine the commissioned underwater hull and external fittings while the vessel remains afloat, subject to port permission, safe access, weather, tide, current and visibility. The inspection areas and reporting standard are agreed before attendance.

Visual inspection records the visible condition and access limitations; it covers the surfaces the diver can see, not internal machinery condition. Where an owner, manager, surveyor or superintendent needs a particular damage area checked, identify its position in the enquiry.

• Hull shell plating visual condition
• Bottom condition and marine growth
• Propeller blade condition and visible damage
• Rudder and external steering-gear visual condition
• Sea chest and seawater intake areas
• Anode condition and visible wastage indication
• Bilge keel, skeg and underwater appendages
• Draft marks and underwater markings if required
• Visible post-grounding or contact damage
• Photographs and video of the commissioned inspection areas

A useful UWI report identifies the areas examined and describes the actual visible condition. General wording such as checked and found normal is insufficient if the owner cannot tell which hull surface, propeller, rudder or fitting was examined.

SVC provides the commissioned underwater photographs and video, diver comments, inspection summary and repair recommendations where warranted. The records let the owner or superintendent examine marine growth, visible damage, deformation, grounding or contact marks and external fittings alongside the written comments.

If the technical review calls for surveyor or owner’s representative attendance, include that as a separate appointed role. Specify the report recipient, required witnessing and the agreed inspection areas in the enquiry.

If inspection finds heavy marine growth, a fouled propeller, an obstructed sea-chest area or another underwater condition affecting operation, SVC divers can carry out a separately appointed cleaning or polishing scope when permission and safe conditions allow.

The owner agrees the work before it is carried out. Inspection footage describes the observed condition; post-cleaning photographs or video describe the worked surface. Keep those stages distinct in the report.

• Underwater hull cleaning
• Propeller polishing
• External sea-chest cleaning
• Rudder and propeller-area cleaning
• Underwater photographs and video after cleaning
• Selected underwater repairs subject to condition and safety approval

Send the vessel reference and the worklist to the SVC repair department. The inspection purpose, selected areas and recording requirement determine the attendance; a port name or a request for a general video alone does not define the scope.

• Vessel reference and vessel type
• Actual port, anchorage or shipyard location in Vietnam
• ETA, ETB, ETD and available working window
• Routine check, damage assessment, pre-purchase inspection, class requirement or drydock preparation
• Required hull, propeller, rudder, sea-chest, anode, draft-mark or specific damage areas
• Photographs, videos, formal diving report and any surveyor attendance requested
• Class, flag, insurer, owner’s superintendent or charterer instructions
• Safe access, isolation limits and the onboard attendance contact

For Vung Tau underwater inspection, provide the actual anchorage or berth and the tugboat’s operating window. For Vissai-Cua Lo underwater work, identify the external inspection areas and any separate cleaning scope. The Cai Mep marine-services page provides the existing port-call service route; confirm the actual berth or anchorage for a dive.

For Van Phong or Cam Ranh, name the terminal or anchorage instead of the province alone. See the Vietnam underwater inspection service for commissioned dive scope and the underwater cleaning and CCTV report for the distinct cleaning-evidence package.
