⚖️ Hold Volume Calculator

Stowage Factor — m³/MT

Cargo Quantity — MT

Broken Stowage — %void space allowance

Volume needed = Quantity × SF × (1 + broken stowage). Max cargo = (Volume ÷ (1 + broken stowage)) ÷ SF. Broken stowage accounts for void space; for trimmed bulk it is near 0%, for bagged/break-bulk it can be 10–25%.

📖 Reference Notes

Group A — cargoes that may liquefy if moisture exceeds the Transportable Moisture Limit (TML). Verify TML/MC certificate; carry out a can-test if in doubt.
Group B — cargoes with a chemical hazard (self-heating, gas emission, oxygen depletion, oxidizing, corrosive, etc.).
Group C — cargoes that are neither liquefiable nor chemically hazardous (but may still be dusty, heavy, or abrasive).
Stowage factor (SF) is volume occupied per unit weight: m³/MT. Multiply by ~35.88 for ft³/LT.
Figures are typical ranges from the IMSBC Code and standard references — the shipper's declaration and vessel cargo documents always govern.
