Ensure Your Assets Are Safe, Reliable & Code-Compliant

Fitness For Service (FFS)

API 579 Fitness-For-Service Engineering Assessments

What Is Fitness-For-Service?

Fitness-For-Service (FFS) is an engineering methodology used to evaluate whether damaged, corroded, or aging equipment can safely continue operating under current or future conditions. Our certified engineers perform FFS evaluations in accordance with API 579-1 / ASME FFS-1, ensuring clear decisions backed by standards and real field experience.

Common Damage Mechanisms We Evaluate

Common Damage Mechanisms We Evaluate

We inspect and assess integrity issues such as:

  • Metal loss & corrosion

  • Cracking & fracture damage

  • Dents, gouging & distortions

  • Weld defects

  • Hydrogen damage

  • Creep & embrittlement

  • Fire & thermal damage

  • Fatigue and stress-related damage

FFS Assessment Levels (API 579 Compliant)

We provide full support across all assessment levels:
Level 1 – Screening / conservative evaluation
Level 2 – Detailed engineering analysis
Level 3 – Advanced simulation using FEM and stress analysis tools
This ensures the most cost-effective, reliable evaluation based on asset condition and urgency.

Equipment We Support

Pressure vessels
Process piping systems
Boilers and heat exchangers
Storage tanks (aboveground & underground)
Structural & rotating components
