Under Annex II, which documentation is required on ships?

• A. NLS Certificate
• B. Cargo Record Book
• C. P&A Manual
• D. Shipboard Marine Pollution Emergency Plan (SMPEP)

Answer: (B)

Under Annex II, the key document ships must carry is the Cargo Record Book. This on-board log records all cargo handling and related operations for noxious liquid substances carried in bulk, including quantities loaded, transferred, unloaded, retained in tanks, and any discharges or residue handling. It provides a clear, traceable record of how each cargo was managed from loading to final disposition, which helps ensure pollution prevention and enables authorities to assess compliance and respond if incidents occur. The other items listed serve different purposes or are not the primary on-board documentation required by Annex II: while an NLS-related certificate shows compliance with standards, and emergency plans or manuals are important planning tools, they are not the central cargo operation record that Annex II mandates to be on board.
