Petroleum coke (’petcoke’) is a bulk by-product of oil refining. Among other end-uses, it is traded as a form of fuel (e.g. for cement manufacture) or an input to other industrial applications (e.g. smelting). It is commonly transported at sea in bulk carriers. As with most other bulk cargoes, after discharge there remain residues in the holds and on deck which must be cleaned before new cargoes can be loaded. The cleaning process typically entails dry sweeping, high pressure water washing, the application of a chemical cleaner and a final high pressure water wash. In theory, the dirty wash water is either disposed of at sea or discharged for treatment in land-based reception facilities.
