Equipment Criticality Assessment

Equipment Criticality Assessment

Improve reliabiliy of assets through equipment criticality assessment

A major part of success and prevention of downtime costs lies in pro-active asset management. An equipment criticality analysis shows which equipment is critical in terms of sustainable operation, production costs, safety, protection of the environment and prevention of legal or class limitations.

ISO9001-14001-18001

Introduction

Pro-active asset management is an integral part of a larger successful business process. The Equipment Criticality Assessment focusses on the maintenance of physical asset reliability.

Apart from that, an Equipment Criticality Analysis focusses on those parts of the asset, which are critical in terms of safety, environment, process / operation or legal/ class restrictions.

This is translated to effective preventive mainte- nance processes and the spare part policy.

Process

Step 1: Build the mother list
Elaboration of the mother list per asset, containing all physical equipment, systems, etc. Items will be numbered with an unique ID. The list can be derived from existing maintenance systems like Star, Marad, Maximo, etc.

Step 2: Assess criticality per item

Assess the degree of criticality by using a proven TOP-method, looking at:

  • Consequence on safety;
  • Consequence on environment;
  • Risk failure starting up;
  • Risk failure in operation;
  • Level Emergency stop;
  • Effect on production;
  • Complexity;
  • Costs repair/ replacement.

Step 3: Implement outcome in maintenance system
Provision of a procedure, describing the chosen method and setup in order to be able to perform and review the assessment at a later stage.

“I CAN PREDICT THINGS. I CAN IMPROVE THE UPTIME AND THE RELIABILITY. I CAN INTERVE- NE AND CAUSE A BETTER OUTCOME BEFORE THERE’S A PROBLEM”

Benefits

1. Compliance with legal requirements and codes (ISM/ ISO 55000);
2. Inherent process safety with reduced capital and operational costs;
3. To the point and realistic output for preventive maintenance proce- dures;
4. Direct input for spare part policy, prevention of too much spares in store or critical spare not available in time;
5. Minimizing of problems during commissioning and early operation;
6. Opportunity of sharing knowledge and decision making and learning across engineering functions.
