Which statement is NOT a requirement for Annex II discharges?

• A. The ship must be en route at least 7 knots
• B. Not less than 12 nautical miles from land
• C. Must be discharged below the waterline
• D. Must be discharged at night only

Answer: (D)

Annex II governs the discharge of cargo residues and washings from ships carrying noxious liquid substances in bulk, with rules designed to minimize environmental impact. To discharge legally, the ship must be en route at a minimum speed (typically at least 7 knots), be at least 12 nautical miles from land, and perform the discharge below the waterline so the residues mix with seawater rather than spreading on the surface. There is no requirement to discharge only at night; that timing is not part of Annex II rules.
