Cut mean time between failure on fans

The problem

Fan solution
A refinery was experiencing an unacceptable number of critical fan failures. Correcting these failures cost 7 850 € each in parts and labour, plus the added high costs of lost production on the line.

The solution

After an assessment to study the causes of failure, SKF developed and implemented an SKF fan system solution that combined maintenance training and tools for customer personnel, as well as an upgraded bearing and lubrication products package.

The result

The refinery was able to realize a number of important benefits:
  • Extended Mean Time Between Failures (MTBF)
  • Reduced unplanned downtime
  • Lower maintenance costs
  • Improved safety
  • Reduced lubrication usage

Return On Investment (ROI)

  • SKF solution ROI over 37 months:  410 % 
  • Net benefit:  € 119 847 
  • (bearings, alignment, training, tools):  € 29 250 
  • SKF solution investment  
  • Total value: € 149 097
  • labour (4 staff x 4,3 hours x 26 € hour x 19): € 8 497
  • Components (7 400 € per fan x 19): € 140 600 
  • Cost of failures: 
  • (increased MTBF from 12 months to 37 months) 
  • Reduction in fan failures:  9 (fewer failures) 
  • Fan population:  12
