INTEGRITY METHODS & DECISION INPUTS

Different integrity questions require different evidence.

Inspection, testing, corrosion control, risk analysis, engineering assessment, materials knowledge, monitoring, and digital systems each answer different questions. Asset Integrity Management connects those inputs to the decision they are meant to support.

METHOD FAMILIES

Methods create evidence. Context gives that evidence meaning.

The method should fit the asset, the suspected degradation mechanism, the operating environment, the decision being made, and the confidence required. No single technique provides every answer.

INSPECTION & NDE

Observe, detect, measure, and characterize condition.

Inspection and nondestructive examination provide evidence about physical condition, location, dimensions, morphology, or change. Capability, access, calibration, coverage, and detection limits shape what can reasonably be concluded.

CORROSION MANAGEMENT

Connect mechanisms, environment, control, and field evidence.

Coatings, cathodic protection, monitoring, process conditions, materials, inspection, and historical performance contribute to understanding corrosion risk and control effectiveness.

RISK & RBI

Use likelihood and consequence to focus attention.

Risk assessment and risk-based inspection can help prioritize where evidence, inspection, mitigation, or review is most valuable when assumptions and uncertainty remain visible.

FITNESS FOR SERVICE & ENGINEERING ASSESSMENT

Evaluate whether observed condition can support continued service.

Engineering assessment brings material condition, geometry, loading, degradation, operating conditions, uncertainty, and applicable criteria together to support asset-specific decisions.

MATERIALS & METALLURGY

Understand what the material is telling the organization.

Material properties, degradation mechanisms, fracture behavior, laboratory findings, failure analysis, and historical records can clarify why damage occurred and what it means for future decisions.

MONITORING, DATA & DIGITAL

Extend visibility across time and across systems.

Condition monitoring, integrity software, connected records, analytics, digital twins, and AI can help organize and compare evidence when data quality, provenance, context, and validation remain intact.

METHOD SELECTION

Start with the integrity question.

WHAT NEEDS TO BE UNDERSTOOD?

Define the condition, threat, or uncertainty.

The first question is what the organization needs to know about the asset, rather than which technology happens to be available.

WHAT DECISION WILL FOLLOW?

Match the evidence to the decision.

Screening, prioritization, repair, continued operation, mitigation, reassessment, life extension, and replacement require different levels and types of evidence.

WHAT ARE THE LIMITS?

Keep capability and uncertainty visible.

Every method has boundaries. Detection limits, assumptions, operating conditions, data quality, model confidence, and validation affect the strength of the conclusion.

FROM METHOD TO DECISION

Technical inputs become useful when they remain connected to operating reality.

A result gains decision value when the organization can see where it came from, what question it answers, what assumptions or limitations apply, how it relates to asset history and operating conditions, and what qualified judgment was used to interpret it.

THE METHOD TEST

Does the method answer the integrity question, and are its limits understood?

Strong Asset Integrity Management connects technical capability to the decision being made, the operating context around it, and the evidence needed to verify what happens next.
