Fitness for Service - API 579-1/ASME FFS-1 2007

Overview:

Introduction:

A plant objective is to attain the maximum economic benefit and service life from existing equipment without sacrificing integrity. This requires an accurate assessment of the condition of the equipment and their suitability for the actual service. Fitness-For-Service (FFS) assessments are quantitative engineering evaluations that are performed to demonstrate the structural integrity of an in-service pressure equipment/component containing a flaw or damage. In June 2007 API and ASME produced a joint update of each society’s version of FITNESS FOR SERVICE.  The new standard is now called API 579-1/ASME FFS-1 2007 Fitness-For-Service. It has become the de facto international standard for conducting FFS assessments. The main deliverables from FFS assessments are improved plant integrity and reduced maintenance costs.

The participant in this integrated and comprehensive course will learn to apply the rules of the API/ASME 579 standard "Fitness-for-Service" to evaluate the integrity and remaining life of pressure vessels, storage tanks, piping systems, and pipelines, to make cost-effective run-repair-replace decisions, and select the appropriate repair options. In this program you will learn:

Course Objectives:

At the end of this course the participants will be able to:

  • Determine the fitness-for-service of operating tanks, vessels, piping systems, and pipelines; and make cost-effective run-repair-replace decisions based on the principles of API recommended practice 579 "Fitness-for-Service"
  • Provides the participants with the tools necessary to recognize and assess defects in pressure vessels, storage tanks, and piping
  • Presents and applies the fundamentals rules of the ASME code to operating equipment and systems
  • Introduce the practical application of the ASME and API rules for the structural integrity of static equipment and pipelines, and their use to assess the remaining life
  • Applies API/ASME 579 "Fitness-for-Service" through practical examples to analyze degraded conditions and make a cost-effective repair or use-as-is decisions
  • Applies the step-by-step 3-level approach of API/ASME 579 to evaluate inspection results and recognize potential failure modes
  • Evaluate the structural integrity of corroded or damaged equipment, and assess their remaining life. Degradation mechanisms include: brittle fracture, general metal loss, local wall thinning, pitting, blisters and laminations, mechanical defects (dents, gouges, misalignment, and distortion), crack-like flaws (stress corrosion cracking, weld flaws, crack-like defects), fatigue, and fire damage
