Understanding Oily Water Separators (OWS): A Key Element for MARPOL Compliance

Oil-contaminated bilge water is an unavoidable byproduct of engine room operations. Discharging this mixture directly into the sea is strictly prohibited under MARPOL regulations. The Oily Water Separator (OWS) system ensures that bilge water is treated so the discharged water contains no more than 15 ppm of oil, protecting both the environment and vessel operators from severe penalties.

Why Is an OWS System Essential?

  • Ensures compliance with MARPOL Annex I
  • Minimizes the risk of environmental pollution
  • Prevents fines and detentions during inspections
  • Supports safer and more sustainable engine room operations
