DNV has published DNV RP F123 Hydrogen Pipeline Systems, a new recommended practice developed through the H2Pipe Joint Industry Project (JIP) to support the safe design, operation and requalification of offshore pipelines transporting hydrogen and hydrogen blends. The document addresses hydrogen-specific integrity and safety challenges, including material behavior and risks such as hydrogen embrittlement.
Tenaris has actively contributed to the H2Pipe JIP, which since 2021 has brought together 37 industry partners to consolidate research, testing and operational experience into practical, engineering-ready guidance, translating years of shared data and technical learnings into recommendations for direct use in engineering projects and qualification activities.
“The real value of the H2Pipe JIP lies in turning shared data into credible, site-ready guidance that engineers can use to scale hydrogen infrastructure,” said Philippe Darcis, Chairman of the H2Pipe JIP Steering Committee and Pipeline Technology Senior Director at Tenaris. “This practical tool helps reduce the ‘unknowns’ that often stall investment. Developed through industrywide collaboration, it provides operators with a robust basis for decision-making, enabling progress with fewer assumptions and greater confidence in safety and performance.”
The recommended practice supplements DNV’s long-established submarine pipeline standard, DNV-ST-F101, providing guidance tailored to hydrogen service. It applies to both new offshore developments and the requalification of existing infrastructure, helping reduce uncertainty around design limits, material suitability and operational requirements, key factors in scaling hydrogen transport as part of the energy transition.
With the launch of Phase 3 of the H2Pipe JIP, which includes large-scale testing, Tenaris continues to support the development of robust standards for offshore hydrogen pipelines, contributing to the safe and effective deployment of hydrogen infrastructure worldwide.
