Planned updates to the Clean Shipping index in January 2022

The Technical Committee of the Clean Shipping Index has decided to update the CSI requirement with new criteria. The changes will be updated in the database from the 31st of January 2022. The changes are regarding the criteria connected to antifouling, sewage and NOx emissions. A criterion has also been added concerning scrubber water.

Antifouling: Scoring will only be received for non-biocidal antifouling paints (7 points). Since antifouling paints that contain biocides pose a risk to aquatic organisms no points are given to this category of paints. The data of the antifouling system used on the vessel is found in the antifouling system (AFS) certificate supplemented by the coating manufacturers, in the Materials Safety Data Sheet (MSDS) and in the Technical Data Sheet (TDS). In certain cases, a direct contact with the antifouling paint producer is needed.

Sewage: Scoring will only be received if ship has an approved sewage treatment plant according to MEPC on board (4 points) or if all sewage is left on land for treatment (5 points).

NOx emissions: Emissions of NOx will be compared with the Tier III-level in MARPOL Annex VI. Scoring is received for main engines and auxiliary engines. Click here for more information. Pdf, 330.8 kB.

New criterion in water and waste called “Scrubber water”: Points are given to ships that do not release any scrubber water but rather meet the Sulphur regulations through the use of either distillate oils, LNG or alcohols. Thus, the use of fuels containing residual oil, such as Very Low Sulphur Fuel Oil (VLSFO) or Ultra Low Sulphur Fuel Oil (ULSFO) do not render any points in this criterion due to the uncertainty in the risks for the marine environment and air quality from the use of such products. This new criterion is added to keep up with the growing scientific evidence that the release of scrubber water has risks for the marine environment.
