RBI

Delivering Intelligent, Risk-Driven Asset Integrity Solutions

At Erika Perkins Consults Nigeria Limited (EPC), we help asset-intensive industries transform conventional inspection program into intelligent, risk-based, digitally enabled Asset Integrity Management systems. Our Enterprise Risk-Based Inspection (RBI) implementation services are developed in accordance with internationally recognised engineering standards including API RP 580, API RP 581, API 571, API 579-1/ASME FFS-1, API 584, API 970, API 510, API 570, API 653, applicable ASME Codes, AMPP guidance, and ISO 31000 risk management principles.

Our methodology goes beyond conventional RBI implementation by integrating engineering assessment, inspection planning, integrity operating windows, fitness-for-service evaluation, damage mechanism management, digital dashboards, and enterprise data integration into a single decision-support platform. The result is a Living RBI Program that continuously evolves with operating experience, inspection findings, management of change, and business risk priorities—enabling organisations to improve safety, optimise inspection expenditure, enhance equipment reliability, and strengthen regulatory compliance throughout the asset lifecycle.

Whether deployed as a secure cloud-based (SaaS) solution or an on-premise enterprise platform, our RBI implementation framework is designed to integrate seamlessly with existing SAP S/4HANA, CMMS, Inspection Data Management Systems (IDMS), process historians, and digital engineering environments, allowing clients to leverage existing infrastructure while meeting their cybersecurity and data governance requirements.

Our Enterprise RBI Implementation Capabilities

1. API RP 580/581 Risk-Based Inspection

We establish enterprise RBI programmes using internationally recognised API methodologies to optimise inspection intervals, prioritise resources, and improve mechanical integrity based on quantified risk rather than fixed inspection frequencies.

2. Probability of Failure (PoF) Assessment

Our PoF methodology evaluates the likelihood of equipment failure by analysing credible damage mechanisms identified in accordance with API 571, incorporating equipment design, materials of construction, inspection effectiveness, corrosion rates, operating history, process conditions, and management system performance.

3. Consequence of Failure (CoF) Analysis

We perform both API 581 Level 1 (Semi-Quantitative) and Level 2 (Quantitative) consequence assessments, considering fluid properties, release phase, inventory, ignition potential, toxic dispersion, environmental impact, business interruption, asset replacement cost, and personnel exposure to establish a comprehensive enterprise risk profile.

4. Damage Mechanism Assessment (API 571 / API 970)

Our specialists identify, screen, and validate all credible degradation mechanisms affecting plant assets through structured Damage Mechanism Reviews (DMRs), ensuring inspection strategies remain aligned with actual operating conditions and process changes throughout the asset lifecycle.

5. Fitness-for-Service (FFS) Assessment

Where degradation approaches allowable engineering limits, our integrated API 579-1/ASME FFS-1 workflow supports remaining life evaluations, flaw assessment, repair justification, rerating studies, and continued service decisions. The solution supports Level 1 and Level 2 assessments, with interfaces for advanced Level 3 finite element analysis where required.

6. Integrity Operating Windows (API 584)

We implement Integrity Operating Window (IOW) programmes that continuously monitor critical operating parameters against approved integrity limits. Real-time exceedance management enables early identification of conditions that may accelerate degradation, automatically triggering engineering review, inspection reassessment, and corrective action workflows.

7. Role-Based Executive Dashboards

Our platform delivers configurable dashboards tailored to different user groups, including Executive Management, Asset Integrity Managers, Inspection Engineers, Corrosion Specialists, Operations, Maintenance, Reliability, and Regulatory stakeholders. Dashboards provide real-time visibility of equipment risk, inspection compliance, IOW exceedances, FFS status, corrosion trends, KPIs, and overall asset health.

8. Digital Integration & Enterprise Connectivity

The solution integrates seamlessly with SAP S/4HANA, CMMS, Inspection Data Management Systems (IDMS), process historians, and other enterprise applications through secure APIs and structured data exchange, creating a single source of truth for inspection, maintenance, and integrity management activities.

9. Flexible Deployment Options

Recognising that organisations have different cybersecurity, IT infrastructure, and operational requirements, our Enterprise RBI platform is available as either:

Cloud-Based (SaaS): Secure, scalable, subscription-based deployment with automatic updates and reduced infrastructure requirements.

On-Premise: Installed within the client’s environment to satisfy strict cybersecurity policies, regulatory requirements, and internal IT governance standards.
