CLASSIFICATION society DNV GL and the Norwegian paint manufacturer Jotun have signed a co-operation agreement to work on improving hull performance.
The project will bring together two performance management services, Jotun's hull performance and DNV GL's ECO Insight to collect and analyse data on hull degradation.
Experts suggest that hull and propeller degradation accounts for up to 17 per cent of the world fleet's fuel costs and greenhouse gas emissions, reports London's Tanker Operator.
Advanced hull coatings or more regular hull and propeller cleaning are considered preventive measures. But there is no proof showing which paint is most best or how often propellers need cleaning, said the report.
"Our hull performance solution combines state-of-the-art hull coatings and application technologies with ISO-CD-19030-2 compliant performance measurements and high performance guarantees," said Jotun hull performance sales chief Stein Kjolberg.
DNV GL will provide Jotun with hull and propeller performance computations based on computational fluid dynamics (CFD) models that include the complete operational range of the vessel.
"This approach generates a much greater amount of baseline data than a conventional model tank test could deliver and provides customers with the information they need to prove that they reduced both fuel consumption and emissions to charterers for example," said DNV GL fleet performance chief Torsten Bussow.
ECO Insight computations also show how much resistance is added over time due to hull fouling.
