What are precautions for loading cargo which may Liquefy ?
Important section- All officers on board bulk cargo vessel must familiarise
Cargoes includes : Concentrates, certain coals & other materials having similar properties as listed in Appendix “A” of code
Concentrates :
heavy, dense cargo with very low SF
absorb moisture until all the concentrate is wet- Moisture Migration
flow state develops if liquid permeates sufficient amount of cargo
Liquefaction produce dense sludge cause free surface effect-affecting stability,structural damage
If list develops can cause negative GM & ship may be lost.
Trim cargo level- irrespective of Angle of Repose
Moisture Content not exceed the TML
Do not stow cargoes which contains liquid in space above or adjacent to it
Do not permit entry of liquid into cargo spaces
If necessary to cool cargo –use water spray
Specially constructed bulk carriers not so restricted by virtue of their structural arrangements – but must have evidence that it is suitable for the type of cargo carried.
