Operators need to maintain asset integrity to avoid unplanned downtime and the associated safety and environmental incidents. Asset integrity management (AIM) ensure that assets deliver the required functions and performance in a sustainable manner. These systems have been proven to drive down inspection, maintenance and repair costs while improving plant reliability and operational safety. AIM manage and mitigate deterioration caused by corrosion and fatigue cracks.
The principal industry sector served by AIM suppliers is upstream oil and gas. The AIM market is primarily driven by increasing investment in the oil and gas sector to meet the escalating global demand. Other leading industries for AIM include electrical power generation, refining, and chemical.
Application of Asset Integrity Management
AIM are used manage the capability of an asset to perform its required function throughout the asset’s lifecycle. The systems help ensure that the people, systems, processes, and resources that deliver integrity are in place, in use and will perform when required.
Asset integrity is managed at each stage of the asset lifecycle, including project design, asset operation and decommissioning. Inspections, auditing/assurance and overall quality processes are just some of the means to execute an effective integrity management program.
Elements of Safety Integrity Management:
Inspection (advanced technologies)
Risk assessment and Risk Based Inspection (RBI)
Maintenance (reliability, predictive and preventive strategies)
Operational and process support (critical operating and process windows)
Process safety and mechanical integrity services
IT support/software tools
Management strategies
HSE strategies
Business and financial modeling
Training in industry codes, standards and regulations
Evaluation and Condition Monitoring of CP System
External Corrosion Direct Assessment (ECDA)
Fitness for Services (FFS)
Health, Safety&Environmental Critical Equipment Systems (HSECES)
Health, Safety and Environmental Impact Assessment (HSEIA)
Process Hazards Analysis Services (PHA)
Quantitative Risk Analysis (QRA)
Reliability Centered Maintenance (RCM)
Risk Based Inspection (RBI)
Safety Integrity Level (SIL)
Risk Based Inspection strategy
Pipeline integrity management typically for corrosion
In-service inspection with routine and specialist non-destructive testing
Condition-based maintenance
Vibration induced fatigue failure solutions
The AIM is used to maintain the asset in a fit-for-service condition while extending its remaining life span in a reliable, safe and cost-effective manner. In the US, AIM programs are deployed to meet API-580, API-581, and PAS 55 requirements.
An asset integrity management system does not exist in isolation. To successfully implement an asset integrity management system in a dynamic operating environment, it is essential that all stakeholders have a consistent and a unified understanding of what the essentials of asset integrity are and how they can be applied in their day-to-day operations, yet this is often cited as among the most significant challenges in achieving an integrity culture within an organization.
Current Trends for AIM
Industrial IoT (IIoT) offers the potential for more automated collection of data which would reduce the labor intensive aspects of inspections for asset integrity management.
