An investigation of the wear diagnosis of marine diesel engines is carried out to confirm the applicability of ferrography.<BR>In this report, as the first step, oil samples taken periodically from engines in service are analyzed by means of both quantitave and analytical ferrography.<BR>Results are summerized as follows:<BR>(1) The initial wear condition of the sliding machinery parts is distinguished from the normal wear condition by the observation of the wear particles concentration (WPC) and/or the wear severity index (Is) .<BR>(2) The quantity of wear particles in the cylinder/system oil increses where crank-pin bearengs failed.<BR>(3) The values of the wear particles concentration (WPC) and the wear severity index (Is) for the cylinder oil increase extremely where the abnormal wear of piston rings occured.<BR>These results suggest that the ferrography for lubricating oil is effective in the monitoning the condition of the diesel engines.
