Introduction

The design codes and standards for piping and pressure vessels provide rules for design, fabrication, inspection and testing of new systems. Piping and pressure vessels do degrade while in-service due to deficiencies from original fabrication or due to different causes of degradation.  Fitness-for-Service (FFS) assessments are quantitative engineering evaluation performed to determine the structural integrity of an in-service systems containing a flaw or damage. The FFS help engineers to make run-repair-replace decisions to help ensure that the system in-service can continue to operate safely.

Fitness-for-Service intends to ensure safety of plant personnel and public while older equipment continues to operate, to provide technically sound fitness-for-service assessment procedure to ensure that different service provide furnish consist life prediction, and to help optimize maintenance and operation of existing facilities.

FFS is an integration of three disciplines; these are materials, inspection, and mechanical analysis.

The course will discuss the three technological triad required for fitness-for-service assessment, and apply that on the piping and pressure vessels systems. All of the above will be presented in connection with the related codes and standards.

Examples will be presented using the known methods and programs. Delegates are asked to bring with them their own laptops to practice some of such exercises.

Objective

Audience

Mechanical engineers, process plant and piping / pressure vessels engineers and inspectors responsible for design, installation, operation, integrity and maintenance of piping systems and pressure vessels are encouraged to attend this course.

Methodology

Our courses are highly interactive, typically taking a case study approach that we have found to be an effective method of fostering discussions and transferring knowledge. Participants will learn by active participation during the program through the use of individual exercises, questionnaires, team exercises, training videos and discussions of “real life” issues in their organizations.
The material has been designed to enable delegates to apply all of the material with immediate effect back in the workplace.
