JOTUN STUDY SUGGESTS HPS ENABLES 20% LOWER CARBON INTENSITY

JOTUN STUDY SUGGESTS HPS ENABLES 20% LOWER CARBON INTENSITY

Wednesday, September 22, 2021 

A Jotun study based on EU Monitoring, Reporting and Verification (MRV) data has revealed vessels using Jotun Hull Performance Solutions reported a 20% lower carbon intensity in operations.

Based on the latest carbon emissions MRV data published by the EU, cargo vessels using Jotun’s Hull Performance Solutions (HPS) apparently reported a 20% lower carbon intensity on average in operations compared to non-HPS peers in 2019 and 2020. Cross-checked statistics 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. Only coatings applied within the three years preceding the emissions report were considered. The internal study carried out by Jotun investigated 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.

The Carbon Intensity Index (CII) set to be implemented by IMO in 2023 focuses on the yearly reduction in emissions during operations. So vessel owners cannot just rely on the 'out-of-dock' effect of a hull maintenance. They need a reliable and effective antifouling solution that will perform consistently throughout the service interval. Maintaining a cleaner hull with minimal fouling means a vessel has less resistance when sailing through water. Consequently, less power and fuel are required for the same speed and this directly reduces the amount of carbon dioxide released. Jotun’s HPS have a proven track record of long-term reliability and will become more important than ever for vessel owners to gain a competitive advantage.

“We thank our customers for their trust in our Hull Performance Solutions and the return on investment it delivers over the service interval,” said Stein Kjolberg, Global Category Director for Hull Performance, Jotun. “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 dry docking 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.”

In actual service, marine fouling, weather conditions and operational factors come into play. While there are multiple ways to reduce the carbon intensity of operations, fouling protection is perhaps one of the most important and simplest. It is already part of every maintenance docking. It is also the one with the most crucial aspect, as the increased resistance of a fouled hull can easily negate efficiency gains from energy saving devices and modifications. The best approach is to use a combination of approaches. In the study based on EU MRV data, container vessels with Jotun HPS reported 49% lower carbon emissions compared to their non-HPS peers, and a 10% advantage over vessels using some 'low-friction' foul-release silicone coatings.

Jotun HPS combines antifouling and application technologies with high-end technical service. The solutions enable vessel owners and operators to maximise hull performance, thereby reducing both fuel costs and greenhouse gas emissions. The performance and impact on vessel energy efficiency can be tracked and measured with transparent methods (ISO 19030), and additional high-performance guarantees that can secure return on investment for customers.
