High Pressure Gas Transmission Systems: Foundation

Course Overview

This five day intensive course provides gas industry pressure control foundation training for managers, engineers and technicians. It includes a combination of classroom and practical tuition for personnel working in power generation, industry and gas supply.

The programme aims to develop knowledge and understanding of the standards and regulations that govern the industry, in particular the safety issues. The design and build of gas transmission systems is covered from both a theoretical and practical aspect. Typical equipment from the various processes is studied and operated.

Hands-on experience is gained in the isolation, maintenance and operation of gas transmission systems. Training is provided in a controlled environment, avoiding operational disruption.

Course Objectives

On completion of this course, by means of classroom sessions and practical workshops, delegates will:

  • Understand the structure of the UK gas industry, the operating standards and the legislation that impacts upon owners and operators of gas pipelines and assets;
  • Recognise safe working practices when working in hazardous areas including site entry, safe use of electrical equipment and emergency/evacuation procedures;
  • Demonstrate knowledge of the standards to which fuel gas supply systems are designed, in particular, pipelines and pressure regulating equipment;
  • Understand the advantages of the various maintenance philosophies available as applied to gas supply pipelines and associated plant;
  • Be able to safely isolate, vent and purge a section of gas pipeline and plant in line with industry best practice.

Who Should Attend

Managers, engineers and technicians involved with gas systems above 7 bar.
