Your examiner asks: "What certificate evidences a chemical tanker's Annex II/IBC Code compliance, separate from its IOPP Certificate?"

A. The International Pollution Prevention Certificate for the Carriage of Noxious Liquid Substances in Bulk (NLS Certificate), issued following survey against the ship's approved P&A Manual and IBC Code certificate of fitness — held in addition to, not instead of, the vessel's IOPP Certificate for its own bunkers/machinery operations.

B. No separate certificate exists; the IOPP Certificate alone covers both oil and noxious liquid substance compliance.

C. The NLS Certificate is issued by the cargo charterer, not the flag state or a Recognised Organisation.

D. The Certificate of Fitness under the IBC Code is entirely separate from, and unrelated to, Annex II compliance.

A. Annex II regulates the carriage of noxious liquid substances in bulk and categorises them by hazard to marine resources/human health as Category X (major hazard, discharge prohibited), Y (hazard, discharge restricted by concentration/distance/speed), Z (minor hazard, less restrictive limits) and OS (Other Substances, evaluated as presenting no hazard, outside the Category X/Y/Z scheme).

B. Annex II only applies to crude oil carried in chemical tankers and uses the same Category A/B/C/D scheme as IMSBC.

C. Annex II categorises substances solely by flashpoint, with no relevance to discharge or tank-washing procedures.

D. Annex II applies only to substances also listed under the IMDG Code; substances not in IMDG are unregulated under Annex II.

A. A mandatory record, analogous to the Oil Record Book, of every cargo and tank-cleaning operation involving noxious liquid substances — loading, internal transfer, unloading, tank washing/prewash, slop disposal, and discharge of residues — with dates, positions, quantities and the substance's category, retained for inspection by PSC.

B. A voluntary commercial log used only to record freight rates and demurrage, with no MARPOL legal status.

C. The Cargo Record Book is required only for Category X substances; Y, Z and OS cargoes have no equivalent recording obligation.

D. The Cargo Record Book replaces the IOPP Certificate for chemical tankers and removes the need for an Oil Record Book.
