This course covers how to assess the fitness-for-service of pressure equipment, piping and storage tanks that have been found non-compliant with the original design condition. The objective with the course is to gain an understanding of the way API579-1/ASME FFS-1 2021 is organized for each of the parts relating to the assessment of corrosion, fracture, creep, mechanical or other in-service damage. The Step-by-Step procedures for each section will be explained and each of the assessment methods will be followed with hands-on examples for students to complete or to be completed jointly. The course will also cover how the procedure offers ways of rerating the pressure equipment. In addition, remaining life assessment options will be discussed for some common damage mechanics such as fatigue and creep, followed by some case studies.

Learning objectives:

  • API 579-1/ASME FFS-1 2021 is used to assess the fitness for service of pressure equipment and storage tanks that have exhausted their intended design condition.
  • Each part of the API579 standard relating to fracture, corrosion, and mechanical and in-service damage will be covered with the step-by-step procedures explained and tested on hands-on
    examples and case studies.
  • The procedure also offers ways of rerating the pressure equipment or re-evaluating the maximum allowable fill height for storage tanks. This rerating is offered with the calculation of the Remaining Strength Factor (RSF). The calculation of RSF will be covered in detail for the relevant parts of the standard.
  • The course will also cover the logic in the understanding of the way API579 is organized, which will help make the standard more approachable.
  • Review of relevant damage mechanics and the way remaining life assessments can be carried out.
  • Part 1: Introduction to Fitness-for Service
  • Part 2: Fitness-for-Service Procedures and general road map for API 579 assessments
  • Part 3: Brittle Fracture and Material Toughness Basics
  • Part 2B: Damage Mechanisms
  • Part 9: Assessment of Crack-Like Flaws (Level 1)
Day 2:
  • Part 9: Assessment of Crack-Like Flaws (Level 2)
  • Part 14: Fatigue assessment
  • Part 8: Weld Misalignment
  • Part 4: Generalized Corrosion
  • Part 5: Localized Corrosion
  • Part 6: Pitting
Day 2:
  • Part 13: Laminations
  • Part 7: Damage (HIC and Blisters)
  • Part 12: Dent and Gauges
  • Part 10: Creep Assessment
  • Part 11: Fire assessment
  • Course wrap up and discussion

Hand-calculated examples will be carried out in each section and options for using BechtFFS software as a comparison with the hand calculations

Annette Karstensen
Annette Karstensen, PhD. is a registered licensed engineer in Australia and United Kingdom with more than 25 years’ experience in Structural Integrity. She has extensive experience with client work covering assessments of engineering components relating to hydro power, fossil power and petrochemical plants. Her main expertise is the application of crack assessment and remaining life assessment procedures such as BS7910 and API 579 to develop allowable crack sizes and/or time for failure for components subjected to cyclic loads or high temperature exposure. Prior to joining Becht, Annette worked 18 years with Quest Integrity in Asia Pacific and 7 years with TWI in the UK predominantly focused on projects relating to Structural Integrity. The last 12 years Annette has conducted more than forty API 579 training courses in Asia, Australia, New Zealand, and Europe.
