Training Course: Process Equipment & Piping Systems

Introduction

Process equipment and piping systems constitute the major portion of plant assets and their integrity and reliability are essential for plant availability and performance. Many process equipment and piping systems are subjected to hazardous service conditions and damage mechanisms which, if not adequately monitored and assessed, could result in major failures with consequential significant injuries and business losses.

It is essential to inspect the process equipment and piping system to detect any damage, characterize it, and assess its impact on the equipment integrity. With so many pieces of equipment and extensive piping systems and networks, it is obviously impossible to inspect totally every piece of equipment or piping in a plant. Therefore, an approach based on criticality, i.e. risk-based, taking into consideration the damage mechanisms and failure risk must be taken.

Objectives

The key objectives of this comprehensive course are as follows:

• To increase the participants awareness and understanding that the mechanical integrity of process equipment depends jointly on the proper design, operation, condition assessment, and maintenance of the equipment.

• To provide the participants with a clear understanding of the degradation mechanisms that process equipment could be subjected to over their operating life, how to identify them, predict and determine their impact, and what appropriate measures can be taken to prevent and control the resultant damage.

• To provide the participants with the knowledge and failure analysis skills they need to conduct damage and failure analysis so as to prevent similar failures from happening.

Benefits

The delegate will gain sound and practical understanding of the major degradation mechanisms in oil & gas plants and refinery process units, how to predict them, how to assess their impact on process equipment over their operating life, and how to prevent and control these degradation and damage mechanisms using best industry practices including API 571 and API 580.

• Enhance knowledge about inspection and testing strategies and methods and their effective application to achieve the highest probability of detection of damage and defects.

• The delegate will achieve a better understanding of the regulations and industry practices pertaining to repairs and alterations to safeguard against related failure and to avoid excessive repair costs.

• Enhance competence and productivity thereby enhancing their competence and performance level and making additional value added contributions to their organizations.

Competencies

Participants will enhance their competencies in the following areas:

• Working knowledge in the mechanical design of pressure equipment and piping systems.

• The inter-dependence of design, operation, and maintenance for achieving mechanical integrity of pressure equipment and piping systems.

• Understanding, prediction, and identification of degradation and damage mechanisms that affect process equipment fitness for continued service and could result in significant potential failures.

• Application of risk-based inspection - API 580.

• NDT methods and their effective application.

• Performing fitness-for-service assessments - API 579.

• Failure investigation techniques and root cause analysis.
