API121-API 579 and ASME PCC-2 : Fitness for Service Assessments and Repair Practices

Overview

Course Description

API 579 Fitness-For-Service (FFS) assessments are quantitative engineering evaluations that are performed to demonstrate the structural integrity of an in-service pressurized equipment that may contain a flaw or damage. The guidelines provided in this standard can be used to make “Run-Repair-Replace” decisions and if found fit for service, projected remaining safe life of the equipment can be determined.

When defects are identified using the procedures provided in the Fitness for Service, and if it is determined that repairs are required, the guidance on repair methods and procedures is provided in the ASME PCC-2: Repair of Pressure Equipment and Piping Standard. This training course is designed to give logical step-by-step procedures to assess the present structural integrity of the equipment, deciding its fitness for continued service, selecting and implementing the correct remedial action. The participants would be explained in detail the mechanics of adopting and applying the rules of API 579 and ASME PCC-2, for day-to-day use in their professional work, by explaining several real life case studies and problem solving. The discussion will also cover the relevant aspects of other Post-Construction Codes, such as API 510 and API 570.

Course Objectives

  • To Understand the in-service degradation and damage suffered by Pressure vessels and Piping.
  • To know the appropriate inspection methods and evaluation of inspection findings.
  • To learn step-by-step methodology for assessment of defects and flaws developed during the service.
  • How to choose between ‘3 R’ options i.e.“Run, Repair and Replace”.
  • Assessment of future remaining life.
  • Address the repair of components when repair is deemed necessary based on appropriate inspection and flaw assessment.
  • Deciding on temporary or permanent repairs.
  • Choosing the appropriate repair plan.
  • Methods of carrying out repairs without causing harm to the equipment.
  • Examination and testing of repaired equipments.
  • Repair Documentation and Reports.


Who Should Attend?

Pressure Vessel/ Piping/ Tank design engineers, process engineers, plant operating engineers and managers

Chemical/ mechanical engineers who are involved in integrity assessment of Columns, Vessels, tanks, piping etc.

Also recommended for the Design engineers, Inspection persons and maintenance engineers involved in Repair, maintenance and trouble shooting of plant equipments in Refining, Petrochemical and Chemical industries.

Individual certification of API 510/ 570/ 653 will be an added advantage to the participants
