When tanks have been washed with crude oil, and ballasted without being water rinsed, the ballast is referred to as _________.

🔍 Key Concepts

• Difference between clean ballast and dirty ballast as defined for tankers • Meaning of segregated and dedicated ballast systems under MARPOL/46 CFR • Effect of skipping a fresh water rinse after crude oil washing a cargo tank

💭 Think About

• Ask yourself: if a cargo tank still has oil residues after washing with crude oil and then is filled with seawater, what is likely mixed into that water? • Which ballast term is used when ballast water is carried in cargo tanks that may contain oil, versus ballast carried in tanks that never contain oil? • Which of these options (clean, dirty, segregated, dedicated) specifically depends on how the ballast water is actually contaminated or not, rather than on the design of the piping or tank system?

✅ Before You Answer

• Verify which term applies when ballast is in a cargo tank that still has oil residue present • Check which terms (segregated ballast and dedicated ballast) relate to special ballast tanks that are not normally used to carry cargo oil • Confirm whether "clean ballast" requires the water to meet a standard of no visible traces of oil at the outlet
