Fitness For Services (FFS)

FITNESS FOR SERVICES (FFS)

For Onshore & Offshore Installations

Pressure equipment is assessed using fitness-for-service evaluations to check them for a wide variety of flaws. The pressure equipment that can be evaluated includes storage tanks, boilers, heat exchangers, piping, pressure vessels, etc. Following are some common flaws for which FFS evaluations are performed:

    •    Fire Damage
    •    Generalized Corrosion
    •    Cracks
    •    Dents
    •    Localized Corrosion/ Corrosion under insulation
    •    Bulging
    •    Blisters and Laminations
    •    Pitting Corrosion
    •    Fire Damage

All types of damage that can take place in the petrochemical and refining industries are evaluated by FCI. The evaluation is performed on a wide variety of the following:

  • Heat exchangers
  • Pressure vessels
  • Storage tanks
  • Process piping
  • Heaters (casing, tubes, and stacks)
  • Transmission pipelines
  • Mechanical components of specialized equipment

Frontier is experienced in the assessment of the following damage mechanisms:

  • Hot tap thermal analysis
  • Brittle fracture, including tank hydrotest exemption
  • Blast loading and other dynamic effects
  • General and locally corroded areas, including pitting
  • Mechanical vibration
  • Laminations and blisters, HIC and SOHIC damage
  • Wind-induced vibration of towers, stacks, and pipelines
  • Bulges and out-of-roundness
  • Modeling of weld residual stresses and incorporation into crack-like flaw assessment
  • Crack-like flaws, including stress corrosion and fatigue crack growth
  • Local PWHT of weld repairs
  • Dents, gouges, and dent-gouge combinations
  • Tank shell and edge settlement
  • Evaluation of hot spots
  • Ring joint flange cracking
  • Heater tube remaining life
  • Fatigue evaluation of welded joints
  • Evaluation of high-temperature equipment for creep and creep-fatigue damage
  • Thermal and mechanical fatigue
  • High-Temperature Hydrogen Attack (HTHA)
  • Fire damage
