MARPOL Annex VI – SOx Related Requirements for Low-flashpoint Fuels and Gas Fuels

The IMO has adopted amendments to MARPOL Annex VI concerning the requirements for using low-flashpoint fuels or gas fuels. This follows the 81st session of the Marine Environment Protection Committee, which adopted these amendments by Resolution MEPC.385(81). The amendments enter into force on 1 August 2025.

Further to Class News 02/2022, IMO Resolution MEPC.385(81) includes a minor amendment to exclude ships which use high-flashpoint gas fuels (e.g. ammonia) from the requirement to fit or designate in-use fuel oil sampling points. The amendments also include a small change to the format of the Supplement to the IAPP certificate, which will be rolled out when the ship’s certificate is next reissued after the amendments enter into force.
