Inspection Frequency vs Maintenance Cost
Implement risk-based inspection intervals under ISO 55001 asset management, prioritising high-criticality equipment to optimise cost and integrity.

Regulations
Business Context
Regular inspections identify deterioration before failures occur, supporting safe and reliable operation. Increasing inspection frequency improves visibility into equipment condition but requires additional labor, shutdowns, and inspection costs.
The Contradiction
Increasing inspections improves equipment integrity.
However, additional inspections increase maintenance costs.
Why the Contradiction Exists
Inspection resources are limited, while equipment condition changes at different rates.
Operational Risks
Too few inspections increase failure risk, while excessive inspections consume unnecessary resources.
Oil Industry TRIZ Analysis
Risk-based inspection programs should prioritize equipment according to failure probability and operational consequences, optimizing inspection resources while maintaining integrity.
Applicable TRIZ Principles
Principle 3 – Local Quality
Principle 23 – Feedback
Principle 15 – Dynamics
Decision Tree
If degradation risk remains low, optimize inspection intervals.
If deterioration increases, expand inspection frequency.
Operational Playbook
Assess equipment risk.
Prioritize inspections.
Execute inspections.
Evaluate findings.
Plan corrective actions.
Review inspection strategy.
Verification Metrics
Inspection effectiveness, integrity findings, inspection cost, equipment failures, and compliance.
