Hierarchy re-organisation/build of existing/new register pre-verified asset equipment data into a structured arrangement of functional systems, subsystems and subset equipment, showing in descending hierarchical order (“parent-child”) their respective functional relationships.

The purpose of the hierarchy is to facilitate identification and allocation of maintenance at the optimum operational (hierarchical) level in order to organise and manage maintenance in the most efficient manner.

Assign a criticality rating to maintainable equipment based on probable failure effects on safety, the environment and production. Criticality Analysis is performed for the purpose of assigning and prioritising maintenance of equipment according to its criticality.

Equipment criticality is also used in Risk Spares Analysis as a factor in the decision logic process.

Develop and assign maintenance strategies and tasks to equipment, appropriate to its functional criticality and at the optimum maintainable (hierarchical) level, and to organise and construct these into a suite of planned maintenance routines (PMR’s). The PMR’s are subsequently arranged and scheduled into a planned maintenance programme, taking into consideration all operational and planning factors and ensuring an even maintenance workload distribution.

The purpose of the maintenance build is to produce a system of planned maintenance that ensures safe, reliable and efficient asset operation in order to maximise asset profitability and comply with legislation, and also to manage and plan maintenance in conjunction with operations.
