IMO DCS in a nutshell
The data collection for IMO’s fuel data collection system (DCS) started on 1 January 2019. DCS aggregates data such as fuel consumption, distance travelled and hours underway for individual ships of 5,000 GT and above.
Connection between the DCS, CII and SEEMP Part III
The aggregated DCS data forms the basis for the CII (Carbon Intensity Indicator) rating and the SEEMP Part III (Ship Energy Efficiency Management Plan). From 1 January 2023 the SEEMP Part III must be verified and onboard ships of 5,000 GT and above to document their plans to achieve their CII targets.
Starting in 2024, the CII must be calculated based on the DCS data of the previous year, and then reported to the DCS verifier to be verified together with the aggregated DCS data. The attained CII and the environmental rating (A to E) will then be noted on the DCS Statement of Compliance (SoC), which will be required to be kept on board for five years.
