Fitness for Service (FFS)

API 579-1/ASME FFS-1 and BS 7910 fitness-for-service assessments for damaged or degraded pressure vessels, piping, and pipeline assets — turning inspection findings into defensible engineering decisions.

TES Canada provides Fitness-for-Service assessments that convert inspection findings into engineering decisions about continued operation, monitoring, repair, rerating, or replacement. Inspection tells us what is there; FFS determines what it means. Our assessments apply the appropriate assessment level for the damage type and consequence — from screening Level 1 calculations through detailed Level 2 and advanced Level 3 analysis — ensuring that the engineering effort matches the complexity and consequence of the assessment.
