Examensarbete för masterexamen

Failures on main and auxiliary marine engines due to issues with engine lubrication is a costly and frequently occurring type of engine failure. This thesis investigates main and auxiliary engine damages caused by lubrication failure, using data acquired from the Swedish Club on insurance claims over the past 11 years. The objective was to identify common causes of lubrication failure and preventive measures with the potential of reducing the frequency of engine damages caused by lubrication failure. The most frequently occurring cause of damage was identified to be water-contaminated lubricating oil, followed by faulty lubricating oil filters and incorrectly performed maintenance procedures. Different root causes of failure were also established, where the most common one was lack of maintenance, followed by previously performed maintenance. To prevent engines from sustaining damage due to lubrication failure, it is vital that maintenance is properly and timely performed. Likewise important is to maintain and monitor the engine lubricant condition. A well functioning engine lubricant condition monitoring scheme enables early detection of engine and lubricant issues. This can be accomplished by regularly performing engine oil analyses and by installing equipment which measures the oil condition in real-time.
