What CCM caught, and what it saved.
Seven cases from vessels using CCM: failures that could have been avoided, wear caught early, and maintenance planned on condition.
Could this engine failure have been avoided?
A leaking injector went unnoticed between port inspections and broke a top piston ring at sea.
Scavenge space monitoring & proactive maintenance
Monthly images exposed which vessels kept scavenge spaces clean and which didn’t, and changed crew behaviour.
Early detection prevents a major breakdown
Rising iron in drain oil on Unit 1 pointed to scuffing rings, caught at sea and fixed at the next port.
Why new piston rings failed within months
Rings were renewed on an oval liner. Without honing or replacement, they could not seat and failed early.
Optimising cylinder lube-oil consumption
Visual evidence showed wet rings at 1.2 g/kWh: 20% over-lubrication that CCM benchmarking brought back to condition.
Predicting time between overhauls
Time-based planning said 25% ring life left. Condition-based forecasting said 74.5%, with replacement due in July 2027.
Correct running-in procedures prolong ring life
Controlled load steps let new rings bed in. CCM images from April to August 2025 prove it.
