Risk-Based Inspection (RBI)

What Is a Risk-Based Inspection (RBI) ?

Risk-Based Inspection (RBI) is a strategic methodology used to optimize inspection planning for pressure equipment, piping systems, and storage tanks by prioritizing actions based on risk, rather than fixed intervals. By evaluating the probability of failure and the consequence of failure, RBI helps facilities reduce downtime, improve mechanical integrity, and maintain regulatory compliance under API 580 / API 581 standards. This data-driven approach ensures inspection resources are focused on high-risk assets, lowering operational costs and enhancing safety, reliability, and asset performance across oil & gas, petrochemical, and industrial plants.Using methodologies aligned with API 580 / API 581, we identify where failures are most likely to occur and what consequences they may have. The result: inspections that actually prevent downtime and incidents, instead of wasting resources on low-risk equipment.

What RBI Solves

RBI puts inspection effort exactly where your facility needs it most.
Excessive inspections on low-risk equipment
Missed degradation in high-risk systems
Unnecessary maintenance spending
Limited visibility into asset risk levels
Compliance gaps in MI and PSM programs
Material or metallurgical issues
Improper installation or maintenance
High-temperature degradation

What Our RBI Services Include

Image

Risk Evaluation (PoF & CoF)

We evaluate:

  • Probability of Failure (PoF) — degradation, damage mechanisms, condition data

  • Consequence of Failure (CoF) — safety, environmental, financial impact

This creates a risk profile for every critical asset.

 

Image

Damage Mechanism Assessment (DMA)

Identification of how assets degrade, based on:

  • Materials

  • Process conditions

  • Temperature & pressure

  • Fluids & corrosion behavior

  • Past inspections and failures

Image

CML & Inspection Optimization

  • Condition Monitoring Location (CML) Optimization

  • Selection of best inspection methods (UT, AUT, PAUT, MT, PT, RT)

  • Interval optimization using risk-based criteria

Image

Corrosion Rate & Remaining Life Analysis

Industry-standard calculations to support:

  • Reinspection intervals

  • Repair timing

  • FFS and rerating decisions

Image

RBI Software + Data Integration

We support RBI programs in:

  • Excel-based tools

  • Common RBI platforms (Meridium, PCMS, InspectTech, Credo, etc.)

  • API 580/581 based methodologies

We can build, implement, or improve your RBI model.
