Guidance on 2024 SEEMP Guidelines

C25045 | 02 September 2025

Notice to: Ship Owners / Managers / Operators / Verifiers

This Circular serves to notify all concerned parties that the 2024 Guidelines for the Development of a Ship Energy Efficiency Management Plan (SEEMP), adopted under Resolution MEPC.395(82) on 04 October 2024, contain an outdated reference in Appendix 2.

Appendix 2, Section 5 currently cites:
2018 Guidelines on the method of calculation of the attained EEDI for new ships (Resolution MEPC.308(73))

This has been superseded and should be replaced with:
2022 Guidelines on the method of calculation of the attained EEDI for new ships (Resolution MEPC.364(79))

Act now

Ship Owners, Managers, Operators, and Verifiers are advised to take note, when updating or reviewing SEEMP Part II, to ensure that all updates and references reflect MEPC.364(79) instead of MEPC.308(73), to maintain compliance.
