Pipeline Operations and Maintenance

Introduction

This course comprises two sections. The first examines the design requirements for process plant piping systems. The second section examines the Operation and maintenance requirements for these systems. In each case, the course goes beyond merely repeating the material contained in the governing standards. It discusses practical applications and typical procedures.

The course also contains sample problems that are put together with written exercises for you to complete.

Objectives

After completion of the course the participants will be able to:

• Understand the total structural integrity of process plant piping systems throughout their useful life
• Discover how the ASME B31.3 code has been correctly and incorrectly applied.
• Ensure the total structural integrity of process plant piping systems throughout their useful life.
• Discuss and apply the design requirements of the ASME B 31.3 Code.
• Achieve higher levels of maintenance excellence in refineries and other process plants.
• Examine and apply the maintenance and inspection requirements of API 570 to process plant piping systems.
• Perform engineering audits of designs and procedures

Training Methodology

The most up to date training methodology is used to present this workshop. The workshop is carefully designed to address practical style of learning and to fully engage participants. Tutorials are used through individual exercises and group discussions. These discussions provide opportunities for personal participation in simulated real situations. During these discussions the participants will discover what they might do and what they can do out of what they are learning. This process makes the training fun filled, fast-paced, challenging and empowering.
