Saipem, an Italian company, has received two certifications from RINA for their innovative approach to subsea hydrogen pipelines. RINA granted Saipem Approval in Principle and Technology Qualification for their hydrogen pipeline safety methodology, focusing on material compatibility and performance evaluation. Saipem's unique protocol assesses the performance of metallic materials and welds under hydrogen flow, ensuring safety during pipeline construction. With 65 years of offshore activity experience, Saipem's track record adds credibility to their ability to plan, realize, and install pipelines for hydrogen transportation. The certification from RINA will enable Saipem to qualify the performance of materials used in subsea hydrogen pipeline construction, paving the way for further qualification processes and scalable procedures. Additionally, Strohm BV secured a significant contract from TotalEnergies for supplying ultra-deepwater pipelines using their thermoplastic composite pipeline technology, demonstrating the growing market for efficient hydrogen transportation. These developments in subsea pipeline technology and material compatibility highlight the evolving hydrogen value chain and the potential for safe and efficient hydrogen transportation between economies.
