Reliability-Centred Maintenance selects maintenance tasks by examining functions, failure modes and consequences. Its strongest contribution to asset integrity is ensuring that protective, monitoring and mechanical tasks are linked to credible failure behaviour rather than inherited routines.
Begin with function
Define what the system must do and the required performance standard. Include containment, isolation, protection and support functions—not only production output. A valve can pass flow yet fail its required isolation function. The technical basis should identify the affected equipment, assumptions, uncertainties, responsible authority and evidence required to close the resulting action.
In practical application, begin with function should be translated into documented requirements for the relevant assets and responsible teams. For this subject, the priority is to ensure that reliability centred maintenance asset integrity leads to an auditable decision, appropriate field or engineering activity, and a defined response when results fall outside the approved basis. Records should remain linked to the asset so future reviews can compare assumptions with actual condition and operating experience.
Analyse functional failures
Identify how the function can be lost and the equipment failure modes that cause it. Connect those modes to degradation mechanisms and operating context. Similar equipment may need different tasks when duty and consequence differ. This keeps the work focused on a decision and prevents a completed inspection or calculation from being mistaken for a fully controlled integrity outcome.

Choose an applicable task
A condition-based task is useful when a detectable warning exists. Scheduled restoration or replacement suits age-related behaviour. Failure-finding is relevant to hidden protective functions. If no effective task exists, redesign, operating change or other risk control may be necessary. Where information is incomplete, the uncertainty should be recorded and addressed through verification, conservative assumptions, additional monitoring or appropriately timed examination.

Interface with inspection
Pressure-boundary inspection and machinery maintenance should share criticality, findings and work history. RCM should not override statutory or code requirements; it can help optimise tasks and reveal dependencies within those boundaries. Applicable codes and standards provide important structure, but their relevance, edition and acceptance requirements must be confirmed for the asset, jurisdiction and client-approved scope.

Review task effectiveness
Check whether a task detects the intended condition with enough lead time for action. Repeated failures, no-find inspections and unnecessary intrusive work are signals to revise the strategy. The review should consider maintenance-induced risk as well. The strongest result is a traceable connection between the observed condition, its engineering significance and the action that protects continued operation.

Produce an integrated programme
Map selected tasks into the maintenance system with interval, method, acceptance, response and ownership. Align them with RBI, corrosion management and shutdown planning so functional reliability and containment integrity reinforce each other. For UAE and GCC facilities, the final approach should also reflect local regulatory obligations, the owner’s engineering practices, environmental exposure and the practical access available during operation or shutdown.

How IAIS UAE can support this requirement
Integrity & Advanced Inspection Solutions UAE can support clients in developing a technically appropriate scope for reliability centred maintenance asset integrity. Depending on the approved requirement, the work may bring together asset records, inspection and monitoring evidence, damage-mechanism knowledge, corrosion or reliability information and engineering review. The purpose is to convert available information into traceable priorities and actions for safe, reliable and cost-conscious asset management. Final deliverables, methods, assessment levels and technical references are established for the equipment, operating context, jurisdiction and client specification.
