Marine propulsion is one of the most critical fields where a predictive maintenance approach may give the best results regarding R.O.I.
A few Euros spent on condition monitoring for used oil analysis can provide precious answers related to “where” and “how” impending failures may be detected beforehand. Minimal amounts of sodium may lead to salt water contamination through the corrosion of heat exchangers & internal cooling systems.
This is even worse if the engines are not routinely running but are seldom used, only in times of leisure. Evaluation of the oil’s quality and residual lubrication properties is vital to the efficiency of the systems.
