Jotun's new tool to forecast carbon intensity of vessel operations
Jotun has created a tool to calculate the CII of individual vessels and project the expected development in CII ratings based on different antifouling coatings. The digital tool will display options in a way that customers can easily visualise, according to the company's release.
Alongside the new tool, Jotun has published a paper that dispels the notion of “low friction” coatings that can improve vessel EEXI purely through theoretical calculations and adjustments. The findings are supported by vessel performance data analysed using the ISO 19030 standard.
The paper highlights that IMO guidelines clearly state that the effect of “low friction coatings” cannot be measured, calculated or certified in isolation. In the case of a sea trial, achieving low hull roughness requires the right surface preparation and skilled application, and not purely on choice of coating.
A premium antifouling keeps the vessel within regulatory expectations, while an ultra-premium antifouling with proactive cleaning delivers the best CII rating - much stricter requirements by the 5th year being the reason for the change from A- to B-rating.
