Fitness-for-Service and Remaining Life

Featured Image

Quest Integrity’s Fitness-for-Service (FFS) engineering assessment is a multi-disciplinary approach to evaluate structural components to determine if they are fit for continued service. The typical outcome of an FFS assessment is a "go/no-go” decision on continued operation. An evaluation of remaining life or inspection intervals may also be part of such an assessment, along with remediation of the degradation mechanism.

Quest Integrity has substantial FFS engineering assessment experience and has applied its approach on a wide range of assets. Our technical experts have been heavily involved in the development of the API 579-1/ASME FFS-1 FFS standard, and many serve on the committee that maintains this document.

We are also the leading provider of Fitness-for-Service software. SignalTM Fitness-For-Service enables end users to perform evaluations that range from routine Level 1 to highly advanced Level 3.

    Remaining Life Assessment Based on Creep Testing

    Quest Integrity’s advanced creep testing service provides accurate and reliable life assessment of components prone to creep damage. This service provides a higher level of accuracy in life assessment techniques based on actual creep property of components. Creep testing assessments enable operators to determine effective inspection intervals, optimize operating conditions and extend component life.
     
    Quest Integrity has extensive experience in creep testing methods such as Iso-thermal, Iso-stress creep rupture testing method and API 579 Omega creep testing.

     


  • Pipeline Defect Assessment
    Quest Integrity possesses a unique combination of industry leading fracture mechanics expertise with data analysis and integrity management experience and software.
    Our integrity management tools allows us to support our clients with both software and consulting solutions whether they are handling anomaly response plans, strain analysis of dents and deformations, fitness-for-service assessments or failure analysis.
