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.
