The Chairman’s Technical Committee, originally created in 1939, became the Technical Coordinating Committee in 1972. The new name was deemed more suitable since it was believed the terms of reference would better allow its members to review future programmes of technical work and make policy recommendations. It was also decided that, for continuity, the Chairman would hold office for three years. The new terms of reference empowered the committee to co-opt additional members whose advice was deemed to be desirable. In the first year, representatives from the Gas Council's production and supply division, marketing division and the SBGI were asked to serve on the committee. This pattern is still followed today with representatives of various bodies such as the HSE, Energy & Utilities Alliance (EUA) formally SBGI, Ofgem and companies dealing with gas supply, distribution, utilisation and LPG sitting on the committee in order to encompass the whole industry.
The four sub-committees advise and report to the TCC and consider all technical matters and new techniques on Natural Gas, LPG, LNG, unconventional gases and carbon dioxide; including the environmental impact of the construction and use of installations relating to:
Gas Transmission and Distribution Committee (GTDC)
- materials and ancillary plant
- health and safety of people
- the safe, construction, commissioning, operation, maintenance decommissioning and ultimate dismantling of plant and equipment and related engineering processes, all in respect of gas production, storage, transportation, distribution and use.
Gas Measurement Committee (GMC)
- meter installations, associated pressure regulation and measurement of flow of gas and measurement of gas quality as it affects the billing of energy used.
Gas Utilisation Committee (GUC)
- utilisation of gas and, in addition where appropriate and with the agreement of relevant leading organisations in the respective field, to include other energy sources such as oil and other fuel gases.
Liquefied Natural Gas Committee (LNGC)
- safe, construction, commissioning, operation, maintenance decommissioning and ultimate dismantling of plant and equipment and related engineering processes, all in respect of gas production, storage, transportation and use.
Technical Panels have balanced representation from the different sectors and are made up of experts involved in the subject matter of the Standard in question. Individuals not representing an organisation or company should be a member of IGEM.
The review of the Standards is a process that holds the integrity of the Standard above everything else. This is why the process is not governed by time. One of the main reasons that the Standards are so highly thought of and trusted is that they are developed and reviewed by experts from the industry. IGEM’s Council oversee the reviewing of the Standards and this responsibility is aided by IGEM Committees who appoint the Panel members.
IGEM’s Technical team assist in the drafting of the Standards and decide what Standards will be reviewed. Industry can comment at all stages of the review process and comments are considered and amendments made accordingly.
