Which certificate confirms that the ship has pollution prevention measures and equipment as required by MARPOL I?

• A. Cargo Securing Manual
• B. IOPP Certificate
• C. International Tonnage Certificate
• D. Ship's Medical Chest

Answer: (B)

The main idea is that MARPOL Annex I sets the requirements for oil pollution prevention, and the certificate that shows a ship meets those requirements is the International Oil Pollution Prevention Certificate. This certificate is issued after a survey verifies that the ship has the necessary oil pollution prevention measures and equipment—things like the oil-water separator, proper bilge handling, and appropriate discharge arrangements—are in place and functioning according to MARPOL Annex I. It stays valid for five years, with mandatory annual checks and a renewal survey before expiration. The other items listed relate to different topics: a cargo securing manual is about how cargo is stowed and secured, an international tonnage certificate concerns ship size/tonnage, and a ship's medical chest covers medical supplies.
