Hull & Structural Inspection Checklist [FREE PDF]

Hull and structural inspections are critical for maintaining the seaworthiness of vessels and are mandated under SOLAS Chapter II-1 and USCG 46 CFR Part 71 and 91, requiring periodic surveys of structural components to verify they meet classification society standards. MARPOL Annex I and the ISM Code Section 10 additionally require structural integrity checks to prevent pollution incidents caused by hull failures, including oil spills from structural breaches in cargo or fuel tank areas.

External Hull Shell Plating

Visually inspect the external hull shell plating for corrosion, pitting, buckling, mechanical damage, and condition of protective coatings.

  • Is the external hull plating free of visible corrosion, heavy pitting, or wastage beyond class allowable limits?
  • Is the hull anti-corrosion coating system intact with no significant blistering, disbondment, or bare metal exposed?
  • Are sacrificial anodes on the external hull present, correctly sized, and not more than 50% depleted?
  • Is the hull free of indentations, buckled plating, or deformation caused by grounding or collision?
  • Are hull sea chests, inlet/outlet grating covers, and overboard discharge fittings in good condition?

Internal Structural Frames & Transverses

Inspect internal framing, transverse web frames, longitudinal girders, and brackets for structural integrity, corrosion, and deformation.

  • Are transverse web frames and longitudinal girders free of cracks, fractures, or weld failures?
  • Is the measured plate thickness of structural members within the acceptable wastage limit per class rules?
  • Are all stiffener end connections and bracket attachments free of cracking or detachment?
  • Are internal frames in cargo holds and ballast tanks free of significant corrosion pitting or section loss?
  • Are all structural penetrations (pipe supports, brackets) properly sealed and free of cracks at weld joints?

Ballast Tanks & Void Spaces

Inspect ballast tanks and void spaces for coating condition, structural integrity, and compliance with SOLAS and IMO enhanced survey requirements.

  • Are ballast tank coating systems in GOOD or FAIR condition per IACS coating condition criteria?
  • Are ballast tank vent pipes, drain plugs, and access hatches in serviceable condition?
  • Is the ballast tank free of sludge accumulation, biological growth, or invasive species?
  • Are structural members within ballast tanks (frames, stringers, floors) free of advanced corrosion?
  • Are all ballast tank access hatches and manholes fitted with serviceable gaskets and properly dogged?

Watertight & Weathertight Integrity

Verify the watertight and weathertight integrity of bulkheads, doors, hatches, and closures throughout the vessel.

  • Are all watertight bulkheads intact, with no visible cracks, holes, or unauthorized penetrations?
  • Are watertight doors operational, properly maintained, and free of damage to sealing faces and gaskets?
  • Are all weathertight closures (skylights, ventilators, storm valves) in good working condition?
  • Are freeboard deck penetrations (pipes, cables, fittings) properly sealed with no signs of leakage?
  • Are bilge alarm systems in all watertight compartments functional and recently tested?

Weather Deck Structural Condition

Inspect the weather deck plating, sheerstrake, deck fittings, and drainage arrangements for structural soundness and compliance with Load Line requirements.

  • Is the weather deck plating free of cracks, significant corrosion, or areas of heavy pitting?
  • Is the sheerstrake and connection to deck plating free of cracks or stress concentrations?
  • Are freeing ports and deck scuppers clear, unobstructed, and of adequate size?
  • Are deck handrails, guard rails, and bulwarks structurally sound and at the correct height?
  • Are deck fittings, ringbolts, pad eyes, and lashing points free of cracking or loose fastenings?

Engine Room & Machinery Space Structural Elements

Inspect structural elements within the engine room and machinery spaces, including double bottom tanks, girders, and tank boundaries.

  • Are double bottom tank structures in the engine room free of advanced corrosion and structural defects?
  • Are engine room floor plates and structural supports in satisfactory condition?
  • Are machinery space bulkheads and tank tops free of oil seepage or water ingress signs?
  • Are hull girder elements (keel, keelson, inner bottom) in the engine room free of deformation or damage?
  • Is the shaft tunnel and sterntube area free of water ingress, structural cracking, or seal leakage?

Inspection Findings & Recommendations

Document overall inspection findings, thickness measurement results, photographs, deficiencies, and recommendations for follow-up surveys or repairs.

  • Were ultrasonic thickness measurements (UTM) carried out at required locations?
  • Are photographic records of all areas inspected captured and referenced in the inspection report?
  • Are all structural deficiencies identified in this inspection categorized by severity and priority?
  • Has a copy of the previous hull inspection report been reviewed for outstanding items?
  • Please provide detailed notes on all deficiencies, measurements, and recommendations from this inspection.
