The IMO Sub-Committee on Implementation of IMO Instruments has failed to agree on whether poor CII performance should be a detainable deficiency.
The Sub-Committee held its 8th session from 25 to 29 July 2022, and considered how the enforcement of CII ratings would be handled. In particular, participants discussed whether Port State Control (PSC) authorities should consider it to be a detainable deficiency if a vessel is noted to be ineffectively implementing a corrective action plan to improve its CII rating under MARPOL Annex VI (after having received an E rating or three consecutive D ratings for its CII rating).
The IMO Sub-Committee on Implementation of IMO Instruments has failed to agree on whether poor CII performance should be a detainable deficiency.
ABS reports that some Member States believed this should be a detainable deficiency, due to the importance of this new CII rating, while others disagreed. They held that implementation of a corrective action plan should be measured over an extended time period, and also acknowledged that the CII regulations are considered to be in a review period until 2026.
It was also noted that there are complexities related to the enforcement of CII that have not been fully assessed, with it being observed that a vessel detention can also negatively affect the CII rating by affecting the ratio of emissions to transport work.
The Sub-Committee will advise MEPC 79 (December 2022) of these views and noted that interested parties may submit proposals for this to the MEPC in the future.
