The experienced bulk density of iron ore fines increases when loaded into the ship's holds; initially as a result of the loading process, and then as a result of particle re-distribution within the material itself due to the vibration and motions experienced within the hold during the voyage. Simply put, Bulk Density = Mass/ Volume.

Iron ore fines (IOF) is a type of bulk cargoes commonly transported at sea. In 2009, casualties of two vessels loaded IOF happened near Indian ports (IMO 2010a, 2010b).These casualties were reportedly caused by liquefaction of IOF due to its high water content when being loaded to the vessels in the monsoon season.
