Ferrographic Analysis of Wear Particles of Various Machinery Systems of a Commercial Marine Ship

The objective of this paper is to present the ferrographic analysis of wear particles contained in used lubricant oil samples that collected from the engines, generators and gearboxes of a commercial marine ship. Flash point, viscosity measurement, ferrography analysis and energy dispersive X-ray analysis (EDX) have been employed to extract the relevant information about the physical aspects of used oil and the wear condition of the parts from generator, gearbox and main engine. The study showed that the application of wear particle analysis and ferrography in particular is an effective means to identify and respond to maintenance needs of marine ships machineries.
