Practical integrity solutions built for real-world operations.

At Prairie Integrity Services, we help operators simplify compliance, strengthen inspection programs, and reduce risk — without adding unnecessary bureaucracy.
Every service we offer is built around one goal: to make integrity management clear, defensible, and efficient.

Our services.

  • Risk-Based Inspection (RBI)

    Aligning inspection priorities with actual risk.

    Whether you’re building an RBI program from scratch or updating an existing one, we help you focus on what matters most.

    - RBI program development and reassessment (API 580/581, AB-505).

    - Damage mechanism identification and probability-of-failure review.

    - Risk ranking, inspection interval calculation, and mitigation strategies.

    - Integration of RBI outcomes into inspection schedules and data systems.

    Deliverables: Clear risk matrices, updated inspection plans, and defensible documentation for ABSA audits.

  • Audit Readiness

    Take the stress out of audit season.

    A strong integrity management system doesn’t just exist on paper — it holds up under review.
    We provide an independent, practical audit preparation service to ensure you’re ready.

    - Program gap assessments against AB-512, AB-505, and AB-506.

    - Documentation reviews and corrective action tracking.

    - Mock audits and pre-inspection interviews.

    - Tailored guidance to close findings.

    Outcome: A confident audit experience with zero surprises.

  • Integrity Assessments

    Bringing clarity to complex integrity decisions.

    When inspection data or corrosion history gets messy, we turn uncertainty into defensible logic.

    - Fitness-for-service (FFS) Level 1–2 evaluations.

    - Corrosion mechanism reviews and thickness trend analysis.

    - Remaining life assessments and inspection optimization.

    - Recommendations for repair, replacement, or continued service.

    Benefit: Evidence-based decisions that balance safety, cost, and production realities.

  • QA/QC & Shop Surveillance

    Independent quality verification — from fabrication to field.

    Our QA/QC and vendor surveillance services give you confidence that fabrication, repair, and installation work meet the applicable codes and your own quality expectations.

    - Weld procedure and welder qualification review (ASME IX).

    - Material traceability, inspection hold-points, and NCR documentation.

    - Witnessing hydrotests, fit-ups, and dimensional inspections.

    - Vendor auditing and quality documentation packages.

    Result: Compliance verified before the job leaves the shop floor.
