RP3.2-11: Fitness for Service assessment of repurposed pipelines to Hydrogen

The outcome of this study will enable the existing operators to perform condition assessment and remaining life calculations for repurposing them to H2. Potential users can re-assess their existing assets (known defects) with a proposed change of fluid, as part of the potential transition from an all-hydrocarbons fluid to a blend of H2, and finally to an all-H2 composition. It will also identify gap in knowledge requiring further research by developing a research roadmap for further research.
