The committee at MEPC 81 adopted amendments to Appendix IX of MARPOL Annex VI, requiring additional data to be submitted through the DCS, as per MEPC.1/Circ.913. This includes data on transport work and detailing fuel oil consumption per consumer type such as main engine(s), auxiliary engine(s), boiler and others, and on whether the ship is underway or not. Additionally, it was agreed to invite for early application of the amendments from 1 January 2025.

These amendments are expected to enter into force on 1 August 2025 while also inviting the parties to consider their early application from 1 January 2025.

Noting the fact that the aforementioned amendments are expected to enter into force halfway through a calendar year, which would result in two distinct levels of granularity for the data gathered in that calendar year, the committee considered a Unified Interpretation (UI) advising that:

• For ships flying the flag of the Administration that implements the amendments early (1 January 2025), to revise and verify the SEEMP prior to 1 January 2025 and to collect data with increased granularity throughout the entire year of 2025 and beyond
• For ships flying the flag of the Administration that implements the amendments on the entry-into-force date (1 August 2025), to revise and verify the SEEMP prior to 1 January 2026 and to collect data with existing level of granularity for the entire year of 2025, and with increased granularity from 1 January 2026
• For ships delivered on or after 1 August 2025 to collect data at the enhanced level of granularity from the date of delivery and onwards
