SEEMP Part II & Collection and Reporting of Fuel Oil Consumption Data 11.05.2025 15:56
Amendments to MARPOL Annex VI Appendix IX enter into force on 1 August 2025 that require ships to collect and report additional fuel oil consumption data in a calendar year.
This additional data includes:
• Fuel oil consumption per consumer type and fuel type (including main engines, auxiliary engines etc)
• Fuel oil consumption while not underway per consumer type and fuel type
• Onshore power supplied to the ship
• Laden distance travelled
• Installation of innovative technologies
• Total transport work
Updates to and Review of the SEEMP Part II
In accordance with MARPOL Annex VI Regulation 5, the ship’s Ship Energy Efficiency Management Plan (SEEMP) Part II will require amendment and review by the flag Administration or Recognised Organisation before the subject ship collects the associated data:
• For existing ships: reviewed before 1 January 2026
• For new ships: reviewed before the ship enters service
Section 7 of MEPC.395(82) sets out the recommended methods to collect this “new”, more granular data related to fuel oil consumption per consumer type. This includes the following methods:
• Using flow meters
• Bunker fuel oil tank monitoring
Owners, operators and managers should consider this data collection at an early stage to ensure the necessary equipment and procedures are in place on board for the 1 January 2026 deadline.
