Fitness-for-Service and Remaining Life

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.

Talk To An Expert

The typical outcome of an FFS assessment is a “go/no-go” decision on continued operation. Such assessments may also include an evaluation of remaining life or inspection intervals, along with remediation of the degradation mechanism. Quest Integrity has substantial FFS engineering assessment experience and has applied this approach to a wide range of assets. Our technical experts have been heavily involved in developing the API 579-1/ASME FFS-1 FFS standard, and some serve on the committee that maintains this document.

We also provide the industry-leading Signal™ FFS software, which enables end users to perform evaluations ranging from the routine Level 1 to the more in-depth Level 2 and advanced Level 3 remaining life assessment.

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 579-1/ASME FFS-1 Omega creep testing.

Fit Creep

Quest Integrity possesses a unique combination of industry-leading fracture mechanics expertise with data analysis and integrity management experience and software. Whether handling anomaly response plans, strain analysis of dents and deformations, FFS assessments, or failure analysis, our integrity management tools allow us to support our clients with both software and consulting solutions.
