Lube oil monitor approved by engine company

Vaisala says that severe damage can be avoided by monitoring wear in the major bearings and water contamination in the lubrication oil. MAN Diesel & Turbo has recently recommended on-line condition-based water-in-oil monitoring for the MAN B&W marine two-stroke diesel engine range, in order to protect critical components.

In order to identify suitable vendors, MAN Diesel & Turbo conducted an extensive test programme of commercial water-in-oil sensors. The goal was to verify the measurement accuracy of the sensors under conditions similar to those in two-stroke marine diesel engine installations. The test results were evaluated on the basis of the accuracy of two alarm level values – a high alarm of water activity 0.5 and 0.9. As a result, the Vaisala equipment was approved by MAN for this purpose.

“The engine is the heart of a ship. Ensuring its operation is a truly business-critical task. It is great that a leading engine manufacturer has identified Vaisala as a reliable supplier with products to suit their needs,” says Senja Paasimaa, regional market manager at Vaisala.
