Corrosion of mild steel by coal and iron ore ScienceDirect
2002-12-1 Corrosion rates were measured inside a bulk carrier (ship) cargo hold that carried coal and iron ore cargo on successive voyages and are shown to be similar to those measured in the laboratory. The relevance of laboratory experiments using fine-particle samples for simulating the corrosion of steel exposed to coal and iron ore cargo is discussed.
Bulk carrier corrosion protection
2019-1-25 Bulk carriers have one of the highest loss rates of the world merchant fleet. During the period 1990-95 the average age of bulk carriers lost through leaks or disappearance was 18 years (Anon, 1996). Coal is more corrosive than iron ore due to the presence of sulphates and chlorides and its ability to produce an acidic leachate. Furthermore
