Ankaa Consulting provides Structural Risk Based Inspection (RBI) Technical Services for offshore and onshore oil and gas assets.
These services help operators manage structural integrity risk and optimise inspection planning.
Our Structural RBI approach focuses inspection effort on high-risk structural components. As a result, operators can improve safety, reduce unnecessary inspections, and manage asset integrity more effectively.
All Structural RBI studies are performed in alignment with recognised international codes, standards, and industry best practices.
and industry best practices, ensuring technical credibility, regulatory alignment, and auditable outcomes.
Structural Risk Based Inspection Overview
Structural Risk Based Inspection is a structured approach to inspection planning.
It defines what to inspect, where to inspect, and how often inspections should be performed, based on risk.
Risk is assessed by considering two key factors.
These are the likelihood of structural failure and the consequence of failure to safety, environment, and operations.
By applying a risk-based approach, inspection resources are directed to safety-critical and high-risk structural elements. Consequently, inspection programmes become more efficient and defensible.
Applicable Codes, Standards, and Guidelines
Ankaa Consulting’s Structural RBI methodology is aligned with, and informed by, the following internationally recognised codes and standards, as applicable to the asset type and project scope:
-
API RP 2SIM – Structural Integrity Management of Fixed Offshore Structures
-
ISO 19901-9 – Structural Integrity Management of Offshore Structures
-
ISO 19902 – Fixed Steel Offshore Structures
-
DNV-RP-C203 – Fatigue Design of Offshore Steel Structures
-
DNV-RP-C201 – Structural Design of Offshore Units
-
DNV-RP-F109 – Risk Assessment of Pipeline Protection (where applicable to structural interfaces)
-
ISO 55000 / ISO 55001 – Asset Management principles (risk-based decision support)
-
Operator-specific and regulatory authority requirements
Where required, these standards are supplemented by engineering judgement, inspection data, and structural analysis results to ensure a practical and defensible RBI outcome.
Our Structural RBI Approach
Ankaa Consulting applies a structured and scalable RBI methodology.
This approach is suitable for offshore topsides, jackets, subsea structures, and onshore facilities.
In practice, our Structural RBI approach includes:
-
Defining structural system boundaries and asset hierarchy
-
Identifying credible damage and degradation mechanisms
-
Grouping structural components to manage inspection complexity
-
Assessing likelihood and consequence of failure
-
Ranking structural elements based on risk
-
Defining inspection strategies and inspection intervals
As a result, the RBI process remains transparent, consistent, and auditable.
Scope of Structural RBI Technical Services
Our Structural RBI Technical Services typically include:
- Structural system review and data assessment
- Risk screening and criticality assessment of structural components
- Definition of inspection strategies based on risk ranking
- Optimisation of inspection scope and inspection frequency
- Development of inspection plans and inspection schedules
- Documentation and reporting suitable for management review and regulatory submission
Where required, RBI studies can be supported by structural reassessment results, fatigue analysis inputs, and inspection findings to enhance confidence in inspection recommendations.
Benefits of Structural Risk Based Inspection
Implementation of Structural RBI delivers the following benefits:
- Improved focus on safety-critical structural components
- Reduced unnecessary inspection scope and cost
- Enhanced visibility of structural integrity risk
- Improved confidence in inspection and maintenance decisions
- Stronger alignment with regulatory and industry expectations
