DNV Releases Recommended Practice for Offshore Hydrogen Pipeline Risk Validation

DNV has introduced a recommended practice (RP) for offshore hydrogen pipelines to reduce design and material uncertainty as subsea hydrogen transport projects progress. The RP, resulting from a five-year joint industry project, addresses hydrogen-specific integrity risks and aims to support early-stage engineering for planned hydrogen corridors connecting Southern Europe and North Africa with Northwest Europe. The next phase involves large-scale testing to validate data and enhance existing pipeline standards.

Developed through a five-year joint industry project, it aims to support engineering and qualification work for hydrogen corridors linking Southern Europe, North Africa, and Northwest Europe. DNV plans to conduct large-scale testing at its UK facility to validate material performance under hydrogen conditions, with results informing updates to the RP and aiding future investments in offshore hydrogen pipelines.
