Marine Diesel Engine Lubrication: A critical component to avoid main engine breakdowns——Detailed Particle Analysis and Other Methods

Contaminants created during the combustion procedure or caused by wear and tear (both normal and excessive) should be removed from the oil therefore debris may damage slipping surfaces, obstruct normal motion and cause precision components to seize.

Contaminants of the nature tend to trigger a series reaction as the resulting put on generates more particles, therefore increasing the rate of deterioration. Even though removing them from the essential oil will reduce this danger, it is equally important to determine the supply of the contamination in order to reduce the possibility of a major breakdown.

A number of methods may be used to analyse lubricating oil for impurities. Such as the detection of asphaltene contamination, spectrometry, microscopy, compound counting and analytical ferrography. In addition to determining whether or not the necessary oil is still suitable for use, these types of tests also provide valuable info regarding the condition of the motor.

Such checks are usually performed ad hoc rather than as a part of the actual vessel’s planned maintenance program. When evaluating the results, all possible influencing aspects should be considered including recent powerplant maintenance and changes to functional conditions and routines. The outcomes should also be scrutinised very carefully for tends, comparing the particular figures with previous reviews.
