By analysing the wiper oil from the underside of the piston, the ship's personnel can monitor the condition of the used oil and thus identify changes promptly.

Improve the efficiency of the engine!

Training Topics:

• Introduction
• Basics of cylinder drain oil
• Cylinder lubrication
• Piston running conditions
• Different lubrication systems 
• Cylinder wear, types of wear and how is it detected and measured/monitored 
• Low/high sulphur fuel – what does sulphur in respect of the lubrication regime? Legislations 
• The sulphur/base balance – optimise the feed rate 
• Cylinder Drain Oil Analysis – onshore/on board 
• Sampling the drain oil, how and when 
• Interpreting results and taking actions 
• Field experience 
• open discussion

Statements from engine manufacturers:

“It is MAN's experience that, in addition to visual checks through the air vents, analysis of the scraper oil can be very helpful in monitoring combustion and cylinder conditions. Examination of wiping oil can detect changes in cylinder wear and aid in lube oil rate optimization programs."

Wärtsilä Switzerland: “Measuring the iron content of the oil from the bottom of the piston can provide very valuable feedback on the piston running conditions in the individual cylinders. It allows the user to optimize the lubrication rate according to the current conditions.”
