Coating supplier Jotun said a study has shown emissions savings on vessels using Jotun Hull Performance Solutions (HPS)
An internal study carried out by Jotun, based on European Union monitoring, reporting and verification (MRV) data and showed that vessels using Jotun HPS reported a 20% lower carbon intensity in operations compared with vessels not using HPS between 2019 and 2020.
The study included major cargo vessel types, including bulk carriers, chemical tankers and oil tankers, with a dataset of almost 9,000 vessels, and the emissions report was verified by accredited parties. Only coatings applied within the three years preceding the emissions report were considered.
Jotun added, “cross-checked statistics also indicate lower carbon emissions than from vessels known to be sailing with some “low-friction” foul-release silicone coatings that claim to offer market-leading performance.”
In the study, container vessels with Jotun HPS reported 49% lower carbon emissions compared with their non-HPS peers, and a 10% advantage over vessels using some low-friction foul-release silicone coatings. Ships are designed to meet the Energy Efficiency Design Index (EEDI) and Energy Efficiency Existing Ship Index (EEXI) requirements but in practice, marine fouling, weather conditions and operational factors come into play.
Jotun global category director for hull performance Stein Kjolberg said, “Vessels using Jotun’s HPS typically have farsighted owners and operators that are willing to invest to achieve the most efficient operations. They are not too focused on the immediate cost of drydocking or short-term returns. They know the resulting fuel savings will eventually outweigh the upgrade cost of antifouling and other similar investments many times over.
“The fact that fuel savings translate directly into lower carbon emissions will further add to the return on investment in that stakeholders in the shipping industry will more strongly prefer and reward vessels with lower carbon emissions moving forward.”
