About this Training
Fitness-for-Service (FFS) is a critical methodology for evaluating whether equipment with flaws, degradation, or damage can continue to operate safely. This course provides in-depth coverage of API 579, which offers structured assessment techniques for evaluating pressure vessels, piping, and tanks with respect to their integrity.
Participants will learn how to conduct Level 1, 2, and 3 assessments, covering typical damage mechanisms such as cracks, corrosion, dents, and fire damage. The course explains how to use FFS assessments to avoid unnecessary repairs or replacements, improve decision-making, and extend asset service life.
By combining theory with practical case studies, this course equips professionals with the ability to perform integrity evaluations, comply with standards, and manage risk effectively in line with API 579 guidelines.
Q1. What is Fitness-for-Service (FFS)?
Fitness-for-Service is a methodology for evaluating whether damaged or degraded equipment can continue operating safely. API 579 provides detailed assessment procedures for pressure vessels, tanks, and piping.
Q2. What types of damage can API 579 assess?
It covers defects such as general and localized corrosion, cracks, dents, bulges, misalignment, fire damage, and weld flaws. Different assessment levels (1–3) provide increasing accuracy.
Q3. What are the levels of FFS assessment?
Level 1: Simplified, conservative screening.
Level 2: More detailed assessment with engineering calculations.
Level 3: Advanced analysis using finite element modeling or fracture mechanics.
Q4. How does FFS support cost savings?
By allowing safe operation of equipment with defects, FFS can prevent unnecessary repairs or replacements. This reduces downtime and extends asset life while maintaining safety.
Q5. What industries apply API 579 assessments?
FFS is used in oil and gas, refining, petrochemicals, power generation, and midstream facilities—anywhere equipment damage must be evaluated for continued service.
Q6. How does FFS relate to RBI?
While RBI prioritizes inspection activities based on risk, FFS evaluates specific equipment conditions to decide if they can remain in service. The two methods complement each other in asset integrity programs.
