Operation and Maintenance the Natural Gas Underground/Above Network

Introduction

This course is designed to provide a theoretical understanding of gas transportation through pipelines underground/above, linked to practical engineering principles, guidelines, codes, and standards using the concept of Natural Gas pipeline design as means of gas transportation. The course covers aspects of Conceptual Engineering, through Design, as well as Construction stages.

It provides the basic underpinning engineering knowledge of theories, equations, and models through to practical applications using case studies of several pipelines from real-life experience at each stage of the training, as well as including software modelling and simulation for the specific stage of design. This unique combination of theory and software modeling helps Engineers to bridge their theoretical and practical understanding of the design of gas pipelines.

Objectives

    The target of this course is to enable participants to:

    • Understand the relevance of gas pipelines as a means of gas transportation for the Underground / above network.
    • Compare options of pipelines and LNG in gas transportation.
    • Understand the flow regimes in gas pipelines.
    • Identify pipeline route and area classifications.
    • Identify compressor stations requirements along gas pipelines.
    • Understand pipeline expansion options and limitations.

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.

Who Should Attend?

  • Process Engineers, Flow Assurance Engineers, Pipeline Engineers, Mechanical Engineers.
  • Instrumentation and Control Engineers, Safety Engineers, and managers or supervisors dealing directly with gas pipelines design, operations, regulations and maintenance
