New sensor and data analysis technology allows in-depth views of ship engines’ lubrication issues. Statistics reveal a range of issues that challenge operators.
With operators challenged by continued economic pressures and changing regulations, the need to protect engines and dri[ds_preview]ve operational efficiencies is more important than ever. Data analysis of more than 400,000 oil samples from ExxonMobil’s MobilGard Cylinder Condition Monitoring (CCM) programme has identified the wide range of potentially damaging engine issues facing vessel operators.
The monitoring service is designed to help optimise engine protection and minimise operating costs. Analysis from the advanced cylinder condition monitoring shows that operators have many opportunities to optimise their engine efficiency and also potentially mitigate catastrophic engine failures.
Most common scenario: over-lubrication
According to the ExxonMobil data, as many as 50% of marine vessels have an opportunity to optimise feed rates. In the most common scenario of over-lubrication, the result is wasted oil consumption and unnecessary expense. But the effects can be far more serious, generating excessive piston and liner wear that can ultimately lead to even more significant costs to operators.
The analysis also demonstrated a growing issue with cat fines and continued cold corrosion challenges for many operators. The statistics show that 43% of vessels have an issue with cat fines, which can lead to catastrophic engine failure in severe cases, ExxonMobil says.
»Many are missing the opportunity to drive efficiency«
15% are suffering from cold corrosion, which can reduce engine life dramatically if operators fail to address the problem quickly. High levels of iron in the scrape down oil were found in 9% of the vessels. This is indicative of engine wear and can lead to reduced piston, liner and overall engine life. 25% are experiencing water washing problems. The presence of water in the engine removes the cylinder oil from the liners and can cause high wear.
»It is no secret that the marine industry is facing challenging times,« said Iain White, Global Marketing Manager at ExxonMobil Marine. »Operators are constantly under pressure to save money, so efficiency continues to be front of mind. The data captured by our MobilGard CCM programme has indicated that many are missing the opportunity to drive that efficiency, and some are even facing a real risk of catastrophic engine failure.«
