Cargo Hold Inspection
Cargo hold inspection is the formal assessment of a ship’s cargo holds to verify they are clean, structurally sound, and fit to receive the intended cargo without causing damage. A passing inspection is required before loading can commence.
Answer in Brief
Before bulk cargo is loaded, an independent cargo surveyor or port authority inspector examines the holds. They check for residues from previous cargo, structural defects, water ingress, and cleanliness standard appropriate for the new cargo. A failed inspection means no loading until deficiencies are corrected.
Who Conducts Hold Inspections?
Independent cargo surveyor: Appointed by the charterer, receiver, or cargo insurer. Their report is the primary commercial document.
National Grain Inspectors (for grain cargo in US): Official inspection required by USDA/FGIS for all grain loaded from US ports.
Port health authority: For some foodstuffs or agricultural products.
Master/Chief Officer: Internal inspection before inviting any external surveyor. You should know what condition your holds are in before the surveyor arrives.
Cleanliness Standards
Hold cleanliness requirements depend on the cargo:
| Standard | Typical Requirement | Example Cargo |
|---|---|---|
| Hospital clean / Grain clean | No previous cargo residue, no odour, no rust scale, dry, vermin-free | Grain, foodstuffs |
| Cosmetic clean | Clean but minor rust staining acceptable | Fertilisers, some ores |
| Shovel clean | Previous cargo residue shovelled out but not swept | Some bulk ores |
| Industry clean | Remove loose material only | Iron ore, coal |
Grain clean is the most demanding and common standard to achieve. It requires:
- All previous cargo residue removed
- Hold swept down
- Any remaining dust vacuumed or blown out
- No rust scale that could contaminate the grain
- No evidence of pests or rodents
- Bilges clean and covers in place
- Hatch covers weathertight (no water ingress)
The Inspection Process
1. Hatch cover examination: Inspector examines hatch cover closing mechanisms, rubber seals, and coaming drainage. Any sign of past water leakage is noted.
2. Visual examination of holds: Inspector descends into the hold (access ladder) and examines:
- Bulkhead surfaces — any previous cargo residue stuck to sides
- Tank tops (floor of hold) — residue, rust, pitting
- Frames and brackets — hidden residue in recesses
- Bilge wells and covers — must be clean, clear, and covered
- Light fittings — must be operational and protected
- Ventilation trunks — clean, no blockage
3. Structural examination:
- Frame corrosion (severe pitting or structural failure)
- Bulkhead plating condition
- Any damage from previous loading/discharging
4. For grain cargo:
- Methyl bromide fumigation certificate (if required)
- Hold certificate (that the hold meets IMO grain loading requirements)
- Absence of any taint-producing substances
When Inspection Fails
Inspector issues a Notice of Failure specifying deficiencies. The ship must correct them and call for reinspection. This costs:
- Cleaning time (1–48 hours depending on deficiency severity)
- Delay charges (demurrage if laytime has already started)
- Reinspection fee
Common reasons for failure:
- Previous cargo residue in corners, bilge wells, or under frames
- Rust scale accumulation on tank tops
- Hatch cover leakage (stains from previous voyage)
- Bilge covers missing or dirty
- Dead insects (grain requires insect-free)
Chief Officer’s Checklist Before Surveyor Arrives
- Walk every hold personally
- Torch every corner, behind every frame, under every bracket
- Check bilge wells: clean, covers in place
- Check all drain plugs in bilge wells are clear
- Confirm hatch cover cleats are operational and seals undamaged
- Confirm ventilation covers can be opened/closed
- Have all previous cargo documents available (Bill of Lading, cargo manifest)
