Indonesian cargo-shipping company Tanto wished to cut lubricant consumption for the two-stroke-engines across its container fleet to reduce its overall operating costs.
Shell Marine proposed a trial using the Shell LubeMonitor service to collect data from one container ship, the Tanto Jaya, to show that the cylinder oil feed rate could safely be reduced and thereby cut lubrication costs.
The data and information collected using Shell LubeMonitor condition monitoring indicated that the feed rate for the Tanto Jaya could safely be reduced from 420 to 396 l/d,
Reducing the cylinder oil feed rate for one vessel in the Tanto fleet potentially saves about $12,420 a year based on a lubricant consumption of 4,320 l/y.1 These savings may increase, as the programme to optimise cylinder oil feed rate is ongoing. Applying the same solution across the Tanto fleet could improve efficiency and help to cut lubrication costs overall.
1The savings indicated are specific to the calculation date and mentioned site. These calculations may vary from site to site and from time to time, depending on, for example, the application, the operating conditions, the current products being used, the condition of the equipment and the maintenance practices.
