Evolving marine fuels sulphur content legislation and the advent of slow steaming have consequences for engine maintenance costs and cylinder oil performance, in turn creating a challenge in maintaining safety margins while optimising operational efficiency. Castrol will present the results of its field evaluations that demonstrate the way slow steaming increases demands on cylinder lubrication. Based on research and development carried out in the laboratory and onboard ship, the company will present data showing that in certain conditions the selection of an 80 BN cylinder oil will prevent cold corrosion if the fuel sulphur level, engine load and feed rate make the lubricant stresses too severe for lower BN lubricants. At a time when the industry is likely to see a higher proportion of fuel bunker deliveries at the highest end of allowable sulphur content range, Castrol will outline why an 80BN lubricant enables optimised feed rates and provides greater neutralisation capacity, and hence better corrosion protection across the fuel sulphur range while slow steaming. Furthermore, as well as offering fuel cost savings, reducing overall speed can mitigate concerns over ash deposits when operating on low sulphur fuels in Emissions Control Areas.
