Codes and Certification Consulting

Our methodology is based on Design by Analysis, according to the most demanding international standards.

When it's needed

Do you need to justify a design beyond formula?

  • Your geometry doesn't fit design-by-formula and must be justified by analysis.
  • The equipment operates in the creep regime or under severe cycles and the code requires specific fatigue and creep assessments.
  • The project targets high-temperature service or next-generation nuclear/renewable environments with advanced code requirements.

What we do

The codes we work with.

Each standard, applied through high-fidelity numerical analysis.

  • ASME VIII Div. 2 + API 579/ASME FFS-1

    Advanced pressure vessel design through numerical analysis.

  • ASME III Div. 5

    Components for high-temperature service and next-generation nuclear/renewable environments.

  • EN 13445-3

    European code for unfired pressure vessels.

How we do it

Complete traceability, from hypothesis to result.

Every code check is performed on high-fidelity simulation results, with the complete traceability that a technical review demands: hypotheses, load cases, acceptance criteria and results, all documented.

What we deliver

Traceable documentation, ready for certification.

  • Complete calculation report with all checks of the applicable code.
  • Traceable documentation, prepared for the project's review and certification process.

Why Vanguard FSI

Technical rigor, controlled risks and calculation ready for certification.

  • A single problem, not two

    Where others treat the fluid and the structure separately, we solve the coupled problem. The mechanical results are based on actual temperature and pressure distributions, not on simplifications.

  • Risks detected at the design stage

    We identify the critical points before manufacturing: it saves prototypes, repairs and surprises during commissioning.

  • Calculation ready for certification

    We work with Ansys Mechanical and Ansys Fluent and deliver complete and traceable calculation reports, prepared for the certification process the project requires.
