A bulk carrier or bulker is a merchant ship specially designed to Transport unpackaged bulk cargo, such as grains, coal, ore, steel coils and cement, in its cargo holds. The term “dry bulk carrier” is used to distinguish bulk carriers from bulk liquid carriers such as oil, chemical, or liquefied petroleum gas carriers. A number of abbreviations are used to describe bulk carriers. “OBO” (Ore-Bulk-Oil) describes a bulk carrier that carries a combination of ore, bulk, and oil, and “O/O” is used for combination oil and ore carriers. The terms “VLOC”, “VLBC”, “ULOC”, and “ULBC” for very large and ultra-large ore and bulk carriers were adapted from the supertanker designations very large crude carrier and ultra-large crude carrier.
