MAINTENANCE RULE OPTIMIZATION

  • Consolidate and Align Maintenance Rule function definitions to the design mitigation function and monitor for loss of that function.

  • Set thresholds for degraded functionality using Condition Monitoring.

  • Design a graded approach so that Maintenance Rule is a backstop.

ILD'S SOLUTION

Maintenance Rule Program savings for an optimized site typically exceed 2.5 person-years per year, representing a substantial reduction in implementation costs and freeing up site personnel to perform other core business activities

THE PROBLEM

  • Maintenance Rule programs are man-hour intensive and duplicate efforts of other programs.

  • They classify equipment problems as functional failures when the design function was not lost.

  • They do not implement a graded approach and assign investigations/evaluations to degraded conditions that are not an actual loss of risk significant functions.
