 ▸ Most common – introduction of formulated cleaners (which contain detergents, water-soluble solvents, water-insoluble solvents and surfactants) by machinery cleaning into the bilge.

▸ Introduction of detergents, which emulsify solvents (e.g., diesel oil and lubricants) already present in the bilge.

▸ Introduction of stabilized solvent formulations from machinery space cleaning that allow residues to enter the bilge and subsequently become emulsified by certain types of pumps often used on OWS units.
