Our Methodology

How We Deliver RBI Programs

A structured, repeatable delivery model built on industry standards - engineered for practical implementation, not just documentation.

Why Methodology Matters

RBI programs fail not because of bad intentions - but because of inconsistent execution, poor data foundations, and models that are never revalidated. Our structured approach prevents all three.

Phase 1

Data Collection & Asset Register Review

We gather existing inspection records, process data, equipment drawings, material specs, and historical corrosion data. A structured data quality review identifies gaps before modelling begins.

Phase 2

Damage Mechanism Review & Circuitization

Our engineers identify active and credible damage mechanisms for each circuit and component - the foundation of any robust RBI model. We document corrosion loops and assign mechanisms per API 571.

Phase 3

RBI Model Development & Consequence Analysis

We build the RBI model, calculate probability of failure (PoF) and consequence of failure (CoF) for each component, and generate the risk matrix. Both qualitative and quantitative approaches are supported.

Phase 4

Inspection Plan Development & Interval Optimization

Risk-ranked components drive optimized inspection plans - specifying scope, technique, frequency, and CML locations. High-risk assets get more focused attention; low-risk assets are safely extended.

Phase 5

Ongoing Revalidation & Evergreening

An RBI model is only as good as its last update. We establish governance and workflow for routine revalidation after inspections, process changes, or turnarounds - keeping the model live and trusted.

Better Risk Visibility

Replace gut-feel inspection decisions with a structured, data-backed risk model that shows exactly where failure risk is highest.

Risk Clarity
Icon forMore Effective Inspection Planning
More Effective Inspection Planning

Focus inspection resources where they matter most - reducing wasted effort on low-risk assets while strengthening coverage of high-risk ones.

Inspection ROI
