As of August 1, 2025, amendments to MARPOL Annex VI Appendix IX will require ships to collect and report expanded fuel oil consumption data. These changes aim to enhance the transparency and accuracy of energy efficiency reporting.
Key Updates:
The additional data required includes:
- Fuel oil consumption by consumer type and fuel type (e.g., main engines, auxiliary engines).
- Fuel oil consumption while not underway, categorized by consumer type and fuel type.
- Onshore power supplied to the ship.
- Voluntary reporting of laden distance traveled.
- Installation and use of innovative technologies.
- Total transport work.
These amendments, adopted under IMO Resolution MEPC.385(81) in March 2024, encourage flag States to implement the changes voluntarily starting January 1, 2025.
Clarifying Data Collection Timelines
To avoid mid-year disruptions, the IACS Unified Interpretation (UI MPC131) and MEPC.1/Circ.913 confirm that:
- Additional data collection should align with full calendar years.
- For ships collecting data under the existing Appendix IX requirements before August 1, 2025, continued collection is required post-implementation to ensure consistency.
- New ships entering service after August 1, 2025, must collect all required data, including the new additions, from their start date.
Action Items for Shipowners and Operators
For Existing Ships:
- Continue collecting existing data through 2025.
- Start collecting additional data per MEPC.385(81) on January 1, 2026.
- Ensure the Ship Energy Efficiency Management Plan (SEEMP) Part II is amended and verified before 2026.
For New Ships:
- Begin collecting all required data upon entry into service after August 1, 2025.
- SEEMP Part II must be amended and verified prior to the ship’s service start.
For Flag States with Early Implementation:
If amendments are adopted before August 2025, ships must amend SEEMP Part II to reflect collection methods and undergo verification by the early implementation date.
Importance of Compliance
