Tackling Cargo Liquefaction

[FONT=comic sans ms]A, B or C?[/FONT]
The International Maritime Solid Bulk Cargoes Code (IMSBC Code) 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.
