Under what conditions is it permissible to pump machinery space bilges directly overboard without processing by an oily-water separator?

🔍 Key Concepts

• MARPOL pollution prevention rules for machinery space bilges (Annex I) • Difference between normal operations and emergency actions for safety of the ship • Requirements and limits when using an oily-water separator (OWS) vs. bypassing it

💭 Think About

• Ask yourself: Are you ever allowed to bypass pollution-prevention equipment during routine operations? • In which situation would protection of life and the vessel legally take priority over pollution rules? • Does “looks clean” or being “far offshore” change the legal requirement to control oil discharge from bilges?

✅ Before You Answer

• Verify that normal bilge discharges from machinery spaces must meet oil content limits (e.g., 15 ppm) and use installed equipment. • Check MARPOL Annex I provisions about discharges necessary to secure the safety of a ship or to save life at sea. • Confirm that merely being beyond a certain distance from land does NOT remove the requirement to control oil content from machinery space bilges.
