Information sourced from industry media, conferences and seminars continues to raise concerns around the variability in the quality of IMO 2020-compliant fuel – very low sulphur fuel oils (VLSFOs).
The industry frequently identifies stability, compatibility, combustibility through to pour point and viscosity as likely key issues to be faced by ship operators come 1st January 2020. Furthermore, some sources have commented that asphaltene precipitation, a phenomenon not usually associated with two-stroke low-speed engines, may also be a concern. To help mitigate the effect of these issues on certain aspects of engine durability, the market requires a more robust lubricant solution.
Marine Diesel Engine Oils technology manager Harriet Brice stated, “It is clear that some of the features of VLSFOs introduce variability that will require higher-performing lubricants with improved deposit handling performance. Utilising our state-of-the-art laboratories and employing our propriety bench and fired-engine testing protocols, we have been able to identify and address these issues through enhanced additive technology solutions.”
Marine Diesel Engine Oils business manager Simon Tarrant added, “Matching IMO 2020-compliant fuel with the right cylinder lubricant to protect and provide engine durability is of crucial importance for ship operators. Our lubricant solutions for VLSFOs provide our customers with the confidence to serve the market through this transitional phase”.
