DNV Releases Guidelines for Safe Hydrogen Pipeline Infrastructure

DNV has published the recommended practice DNV-RP-F123, focusing on the design and operation of offshore hydrogen pipelines. This guideline addresses the unique risks associated with hydrogen, such as hydrogen embrittlement, which can compromise pipeline integrity. Developed through the H2Pipe joint industry project from 2021 to 2026, it consolidates research and testing to provide actionable guidance for both new and existing pipeline infrastructures. The practice complements the long-standing DNV-ST-F101 standard for natural gas pipelines. DNV aims to facilitate the transition to hydrogen transport, which is crucial for reducing emissions in hard-to-decarbonize sectors. The new guidelines will help organizations make informed decisions about requalifying existing infrastructure for hydrogen service. DNV is also moving towards full-scale testing to validate the data and refine the standards further.

Key Points: • DNV-RP-F123 provides guidelines for safe hydrogen pipeline design and operation. • The practice addresses risks unique to hydrogen, including hydrogen embrittlement. • Developed through the H2Pipe project, it involves 37 industry partners for comprehensive guidance.
