- —Scalable from single-unit assessments to full-facility RBI programmes
- —Deliverables compatible with common RBI software platforms
RBI Program Reassessment
Periodic reassessment and update of existing RBI programs to incorporate new inspection findings, process changes, and evolving damage mechanism understanding — maintaining program validity and inspection effectiveness over time.
- —Structured reassessment of existing RBI programs against current operating data
- —Integration of recent inspection findings and turnaround results

Inspection Interval Optimisation
Engineering-led optimisation of inspection intervals based on assessed risk, damage rates, and inspection effectiveness — reducing unnecessary inspection costs while maintaining equipment integrity and regulatory compliance.
- —Risk-informed inspection interval determination based on assessed damage rates
- —Remaining life calculations supporting interval extension or reduction decisions
- —Inspection effectiveness evaluation for current and proposed methods
- —Documented engineering rationale for each interval recommendation
- —Alignment with jurisdictional and regulatory inspection requirements

- —Reduction of unnecessary inspection costs on low-risk equipment
- —Prioritisation of inspection resources toward higher-risk items
Consequence of Failure Assessment
Assessment of potential consequences arising from equipment failure, covering safety, environmental, production, and financial impact scenarios to support risk ranking within RBI and integrity management programs.
- —Safety, environmental, production, and financial consequence evaluation
- —Release scenario modelling for flammable and toxic fluid services
- —Consequence analysis aligned with API 581 methodology
