A cleaner engine and an end to cold corrosion thanks to Mobilgard™ 5100

LOOKING CLOSER

Cold corrosion issues were resolved and a significant reduction in cylinder oil consumption was realised by switching the Colombo Express to Mobilgard™ 5100.

Following modification the Hyundai-MAN B&W 12K98ME engine of the container vessel Colombo Express started to suffer from cold corrosion. To address the problem ExxonMobil ran a field trial to monitor the performance of Mobilgard 5100, a 100 BN cylinder oil. On-board and laboratory analysis of scrape-down samples enabled engineers to gauge wear and optimise feed rates. During the tests the vessel ran at a slow-steaming pattern of 20 to 30 per cent load.

Scrape-down samples showed that cold corrosion was eliminated as a result of switching to Mobilgard 5100, while older black marks and carbon deposits were reduced. Sweep test findings also highlighted that Mobilgard 5100 performed well at minimum feed rates, realising a cost saving due to reduced lubricant consumption.
