The pattern
On many vessels CLO dosing is kept high “just in case”. It is safe, but it wastes oil and money. Manual or conservative settings ignore actual liner wear rate, ring/crown/liner condition, residual oil analysis, load profile and fuel quality.
What CCM showed
Visual cues (wet rings, heavy scavenge deposits, oil pooling, or dry scratched surfaces) reveal over- or under-lubrication but are easy to miss. CCM correlates this evidence with feed rates and oil analysis, and benchmarks against the fleet average for the same engine type.
