Amendments to Appendix IX of MARPOL Annex VI, mandating increased granularity in DCS fuel oil reporting, were adopted at MEPC 81. Additionally, the SEEMP Guidelines were revised, supporting the MARPOL amendments. The new requirements will take effect from 1 January 2026 for most ships1. However, for newbuilds delivered on or after 1 August 2025, the requirements will apply immediately from delivery date.

A revised and approved SEEMP Part II, along with a new Confirmation of Compliance (CoC) confirming compliance with the 2024 SEEMP Guidelines, must be on board by 1 January 2026.
