MobilGard™ Cylinder Condition Monitoring (CCM) is our scrape down oil analysis programme designed to:
- Optimise cylinder oil feed rates
- Extend piston overhauls*
- Control cold corrosion
The programme ultimately helps operators identify the most appropriate base number (BN) cylinder oil and determine the optimal feed rate.
Managing cold corrosion
OEMs including MAN Diesel & Turbo and Winterthur Gas & Diesel Ltd (formerly Wärtsilä) recommend the scrape down oil analysis for engines susceptible to cold corrosion – including the latest engine designs and those modified to optimise fuel consumption.
MobilGard CCM involves taking regular cylinder oil scrape down samples from the scavenge drain system. Tests are carried out on each sample to determine iron content and residual BN levels using onboard measurement units – allowing us to give detailed recommendations for vessel operators regarding cylinder oil and engine operation.
