From 2023, the IMO DCS data will be subject to the CII rating, and a rating (A, B, C, D or E) will be given to each ship from 2024.

The ships subject to the CII rating are required to develop a SEEMP (Part III) to include "CII calculation methodology", "Required CII values over the next 3 years", "implementation plan for achieving the required CII" and "procedures for self-evaluation and improvement", which should be confirmed by the Administration or an RO.

The ships subject to the IMO DCS are required to develop a ship fuel oil consumption data collection plan (SEEMP Part II) and the plan should be confirmed by the Administration or an RO.
