Tackling Cargo Liquefaction


[FONT=comic sans ms][U][B]A, B or C?[/B][/U][/FONT]
[U][B]The International Maritime Solid Bulk Cargoes Code (IMSBC Code)[/B][/U] sets out the internationally agreed provisions for the safe stowage and shipment of solid bulk cargoes, including cargoes that might liquefy.

The IMSBC Code classifies cargo into Group A, B and C cargoes.

• Group A Cargo: cargo that may liquefy if shipped at a moisture content in excess of its transportable moisture limit (“TML”), such as mineral ores and mineral concentrates.

• Group B Cargo: cargo that may possess chemical hazards.

• Group C Cargo: cargo that is neither liable to liquefy nor does it possess chemical hazards.

Group C cargoes have been known to exhibit Group A cargo characteristics – especially when wet. Nickel ore, iron ore fines, and bauxite, for instance, have all exhibited liquefaction properties despite being originally unclassified or listed as Group C cargoes.
