Course Content – Fitness-For-Service

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.

Day1:

Introduction to FFS and API-579
Factors influence brittle fracture and Level 1 and 2 Brittle fracture assessment
