Cylinder liners’ wear rate has been significantly increased, while on the majority of 2-stroke engines, operators are struggling to efficiently balance the cylinder oil type and feed rate in accordance with new bunkers’ sulfur content and properties.

CHRIS MARINE together with TECHNAVA SA, provide complete solutions in 2-stroke engines Cylinder Condition Monitoring by utilizing qualified Service Engineers and state-of-the-art LDM (Liner Diameter Measurement) device combined with a fully detailed service report.

In order to be one step ahead and meet customers’ demanding requirements, CHRIS MARINE utilizes their great experience in engines’ reconditioning and, upon engineer disembarkation, an official Wear/Replica Analysis report is compiled in the Headquarters of CHRIS MARINE in Sweden.

This report may include upon request:

• Wear data
• Replica Sampling Microscopic Analysis
• CTM (Coating thickness measuring) data
• Chris Marine LCC (Liner Condition Camera) photos that documents the condition of the cylinder liners surface
• Important technical recommendations for the improvement of M/E Cylinder liners’ condition

Benefits of LDM

• Measures safely, fast (1 hr/liner) and accurately M/E liners’ wear
• No need to open cylinder heads for LDM measurement
• Device enters the liner through air scavenging ports and is placed on the piston crown
• Capable of measuring liners from 500mm – 980mm bore size
• Takes port-starboard and front-aft measurements
• 36 measurements in TDC levels – Clover measurement
• Ideal equipment for preventive maintenance
