Fitness For Service Evaluations
API-579 / ASME FFS-1 Fitness-For-Service Evaluations are Performed to Demonstrate Structural Integrity of Tanks, Vessels, Silos and other Process Equipment that Exhibit Damage or Contain Flaws/Cracks.
Fitness for Service (FFS) assessments are conducted to API and other relevant Codes to determine whether damaged equipment (such as distortions or cracks) found by inspection is suitable for continued service. This also applies when a large deformation occurs due to unexpected single load. Fitness for Service Evaluations are an important aspect of an Asset Integrity Program in determining the safety and financial risk factors related to component repair or replacement.
There are many factors that affect plant aging. In the current competitive marketplace, extending the life of existing structures and components has become increasingly important in minimizing the total cost of ownership.

We perform Fitness for Service assessments in accordance with API 579 / ASME 579 FFS-1 to extend equipment life. This work includes assessments for clients in various industries, including pressure vessel fatigue life evaluations, assessment of undocumented equipment, and critical flaw sizing assessments.
Core asset failure can have far reaching consequences, which impact reputation, scheduling, and your bottom line. FFS evaluations often result in lower maintenance & operating costs as well as improved plant safety. Read our article on Fitness for Service in Stainless Steel World. (PDF).
