Oily Water Separator Operator

The oily water separator operator is the engine-rating training topic covering the correct use of the OWS, the bilge-water treatment equipment that must discharge below 15 parts per million of oil under MARPOL Annex I Regulation 14. Proper operation, oil-content-meter integrity, and accurate oil record book entries are critical: bypassing the OWS with a magic pipe is among the most prosecuted MARPOL offences. Training reinforces the legal and technical limits of the equipment.
