On 17 May 2019, MEPC 74 adopted resolution MEPC.321(74) to introduce the 2019 Guidelines for port state control (PSC) under MARPOL Annex VI chapter 3.

The 2019 PSC Guidelines are intended to provide basic guidance on the conduct of PSC inspections for compliance with MARPOL Annex VI and afford consistency in the conduct of these inspections, the recognition of deficiencies and the application of control procedures.

The 2019 PSC Guidelines are applicable from 1 January 2020 when exercising port State control under MARPOL Annex VI.

It is noted that the 2019 PSC Guidelines revoke the 2009 Guidelines for PSC under the revised MARPOL Annex VI adopted by resolution MEPC.181(59) from 1 January 2020.

The PSCO should ascertain the date of ship construction and the date of installation of equipment on board which are subject to the provisions of the Annex, in order to confirm which regulations of the Annex are applicable.

5. for a ship to which regulation VI/13.5.1 applies for a particular NOX Tier III emission control area and that has one or more installed marine diesel engines certified to both Tier II and Tier III or which has one or more marine diesel engines certified to Tier II only1 that there are the required log book and the recordings for the tier and on/off status of those marine diesel engines while the ship is within an applicable NOX Tier III emission control area;

6. the Approved Method File (regulation VI/13.7);

7. the written procedures covering fuel oil change over operations (in a working language or languages understood by the crew) where separate fuel oils are used in order to achieve compliance (regulation VI/14.6);

8. the approved documentation relating to exceptions and/or exemptions granted under regulation VI/3;

9. the approved documentation (SECC where issued, ETM, OMM, SECP) and relating to any installed Exhaust Gas Cleaning System (EGCS) or equivalent means, to reduce SOX emissions (regulation VI/4);

10. that the required EGCS monitoring records have been retained and show compliance. Additionally, that the EGCS Record Book including nitrate discharge data and performance records,2 or approved alternative, has been duly maintained;

11. the bunker delivery notes (BDNs) and representative samples or records thereof (regulation VI/18);
