SEEMP Part I, II, III

The Ship Energy Efficiency Management Plan (SEEMP) is the mandatory operational document under MARPOL Annex VI Regulation 26, in three parts. Part I is the management plan for improving energy efficiency, required since Chapter 4 entered force on 1 January 2013. Part II is the data collection methodology for the IMO DCS fuel reporting, required from 2019. Part III, added by MEPC.328(76) from 1 January 2023, sets the ship’s plan to meet its required CII year by year and must be verified and carry a corrective action plan if the ship is rated D for three years or E. The three parts together link design and operational efficiency to the CII regime.
