· Iron Ore Fines (IOF) are a product of iron ore, commonly having a particle size less than 6.3 mm, which is transported around the world in bulk carriers. Since the holds of bulk carriers are not designed to carry liquid, if liquefaction of IOF or other minerals occurs, it can cause the vessel carrying the cargo to list or even capsize.
