Your vessel built after 01 January 2000 and due for International Air Pollution Prevention Certificate renewal survey.

The IAPPC (International Air Pollution Prevention Certificate) is issued under MARPOL Annex VI. As the 2nd Engineer, I would prepare by:

1. Reviewing the MARPOL Annex VI requirements and the ship's IAPPC, the NOx Technical File, the EIAPP certificates, and the SEEMP/energy data.
2. Ensuring the engines (main and auxiliary) are in compliance with the NOx requirements: the NOx Technical File is on board and correct, the engines are operating within the certified parameters, and any NOx-reduction device (SCR/EGR) is functional.
3. Ensuring the fuel oil quality and sulphur content comply: the bunker delivery notes (BDN) are on board and correct, the fuel changeover to low-sulphur fuel in ECAs is recorded, and the designated fuel oil sampling points are fitted and accessible.
4. Ensuring the ODS (ozone-depleting substances) record is maintained and that no ODS is being emitted; the refrigeration systems are leak-free.
5. Ensuring the incinerator (if fitted) is operational and complies with the requirements (approved type, correct operation, no prohibited waste).
6. Ensuring the VOC control (for tankers) and the exhaust gas cleaning (scrubber, if fitted) are in order.
7. Carrying out the required tests and checks (e.g. the engine operation, the fuel sampling, the ODS record) and preparing the engine room for the surveyor's inspection.
8. Coordinating with the Chief Engineer and the Master, and ensuring the survey is scheduled at the appropriate time.

• The current IAPPC and the previous survey reports.
• The NOx Technical File and the EIAPP certificates for the engines.
• The bunker delivery notes (BDN) and the fuel oil records (sulphur content, the fuel changeover log).
• The ODS (ozone-depleting substances) record book and the refrigerant log.
• The SEEMP and the energy-efficiency data (EEXI/CII, the fuel consumption records).
• The engine log and the maintenance records (engine operation, the NOx-relevant adjustments).
• The incinerator records (if fitted) and the type-approval certificate.
• The VOC control records (for tankers) and the scrubber records (if fitted).
• The records of the tests carried out (engine, fuel, ODS).
• The relevant procedures (fuel management, NOx compliance, ODS management) and the crew's training records.
• The IOPPC and other MARPOL certificates as supporting documents.
• The surveyor will verify that the ship complies with MARPOL Annex VI, so all the records and certificates must be current, accurate and available.
