As operators look to repurpose existing natural gas pipelines for hydrogen, understanding how existing pipeline defects behave in a hydrogen environment becomes critical, especially when crack inspection data is limited or unavailable.

In the 30th issue of Dar Magazine, Penspen’s Head of Asset Integrity – East Region, Nick Molnar features, exploring how historical hydrostatic test data can be reinterpreted to infer representative crack populations and support engineering critical assessments (ECAs) for hydrogen repurposing. 

Nick discusses how these insights can be combined with pressure cycling and hydrogen-specific material considerations to prioritise integrity actions across large pipeline portfolios, providing a practical, data-driven pathway for managing hydrogen conversion risk.
