Amendments to MARPOL Annex I (by way of addition of a new regulation 43A) introduce a prohibition on the use and carriage for use as fuel of heavy fuel oil (HFO) by ships in Arctic waters on and after 1 July 2024.

Regulation 18.5 of MARPOL Annex VI requires ships of 400 gross tons and above to have on board a Bunker Delivery Note (“ BDN”) which records details (as set forth in Appendix V) of fuel oil delivered and used on board for combustion purposes. The BDN also provides the designation requirements for refiners, importers and distributors. The BDN now includes a selection box obliging the purchaser to obtain a notification from the fuel supplier’s representative that fuel is intended to be used in compliance with MARPOL, if the fuel supplied exceeds the 0.5% sulfur limit.

In December 2022, the MEPC adopted amendments to Annex V making it mandatory to include the flashpoint of fuel oil or a statement that the flashpoint has been measured at or above 70˚ C in the BDN. This amendment entered into force on 1 May 2024. At its 80th session, MEPC approved new unified interpretations to Regulations 18.5 and 18.6 of MARPOL Annex VI stating that the BDN is acceptable in either hard copy or electronic format.
