This Hazardex Live 2025 presentation will see Karen Warhurst, Senior Principal Consultant at DNV, speak on behalf of the Institute of Gas Engineers & Managers to describe the key changes in Edition 3 of IGEM/TD/2. The revised code, and its content, is considered to represent the current UK best practice for QRAs of high pressure natural gas transmission pipelines.

IGEM publishes a range of technical standards that are widely used throughout the gas industry including IGEM/TD/1 “Steel pipelines for gas transmission” and IGEM/TD/2 “Assessing the risks from high pressure gas pipelines”. Edition 1 of IGEM/TD/2 was published in 2008 in response to the increasing use of Quantitative Risk Assessment (QRA) techniques to assist operators in managing the risks from high pressure natural gas transmission pipelines. A substantially revised Edition 2 of IGEM/TD/2 was published in 2013.  Since publication of Edition 2 in 2013, several areas where it would be useful to refine and extend the guidance in IGEM/TD/2 and to capture recent developments were identified in the light of experience.
