Your examiner asks: "What certificate proves Annex I compliance, who issues it, and what is its validity?"

A. The IOPP Certificate is issued by the P&I Club as evidence of pollution liability insurance, not by the flag state.

B. The IOPP Certificate is issued by the cargo surveyor at each port of loading and is valid only for that single voyage.

C. The IOPP Certificate has no fixed validity period and remains valid indefinitely once issued, provided the Oil Record Book is maintained.

D. The International Oil Pollution Prevention (IOPP) Certificate, issued by the flag state or a Recognised Organisation acting on its behalf following survey, is valid for up to 5 years subject to annual and intermediate surveys/endorsements. It must be carried on board and produced to PSC on request, along with the supporting Record of Construction and Equipment.

A. Ships of 400 GT and above must carry an Oil Record Book (Part I, machinery space operations) and a SOPEP (Shipboard Oil Pollution Emergency Plan); tankers of 150 GT+ also need Part II (cargo/ballast operations). All oil tankers and ships of 400 GT+ must hold an IOPP (International Oil Pollution Prevention) Certificate. Oil filtering equipment/oily water separator is required, generally limited to discharging at no more than 15 ppm oil content outside special areas.

B. Only oil tankers above 5,000 GT need an Oil Record Book. SOPEP is voluntary and recommended only by the company P&I Club.

C. All ships regardless of size must carry an IOPP Certificate and a Garbage Record Book under Annex I.

D. The Oil Record Book is only required while the vessel is within a Special Area; outside Special Areas no oil-discharge record-keeping is required.

A. A SOPEP only contains a list of approved dispersant chemicals and their application rates.

B. A SOPEP contains: the master's reporting procedure and authorities to contact (including national contact lists, which must be updated periodically — commonly every 3 months); a list of shipboard officials responsible for combating spills; procedures for reporting oil pollution incidents; steps to control/minimise the discharge; coordination with national/local authorities; and equipment/material lists for spill response on board.

C. A SOPEP is a class society survey checklist used solely during the annual Annex I survey, with no operational content.

D. A SOPEP applies only to oil tankers; non-tankers carry a SMPEP (Shipboard Marine Pollution Emergency Plan) instead and have no SOPEP requirement.
