OIL ANALYSIS AND DIAGNOSIS OF ENGINE CONDITION

The analysis of engine oils, from samples taken from lubricating-oil systems, can benefit the shipowner by detecting contamination, engine malfunctions, and changes in oil characteristics, and should lead to lower operating costs, reduced maintenance needs, and fewer unscheduled engine shut-downs. After briefly describing these benefits, the paper discusses the requirements that an oil-analysis service should fulfil, and describes how the Mobil analysis service operates. This service is available at over 250 of the world's ports; the actual analysis is done at one of over 30 testing laboratories. Among the aspects considered in the paper are:--sampling frequencies for main and auxiliary engines; sampling location in the system; method of sampling; types of routine tests conducted and information obtained (these tests concern viscosity, flash point, fuel dilution, total base number, strong acids, insolubles, oxidation products, and water content); interpretation of results of tests; transmission of analysis report to shipowner; procedures for reviewing test programmes and establishing limiting values for the variables measured; services, outside the analysis service, available from the laboratories. Some information is included on the Mobil EM/PA (Engine Maintenance through Progressive Analysis) system, which has been successfully applied to non-marine engines and to marine engines in local service.
