Saipem, a renowned player in the energy and infrastructure sectors, has achieved significant milestones in the qualification of materials for subsea hydrogen pipelines. By developing a performance evaluation methodology, Saipem aims to address the critical issue of material integrity when transporting hydrogen through pipelines. The certifications from RINA, namely the Approval in Principle (AiP) and Technology Qualification, mark a pivotal step towards ensuring the safety and efficiency of hydrogen transportation infrastructure. The risk of material degradation is a key concern in the transportation of gaseous hydrogen, necessitating rigorous evaluation protocols. Saipem's protocol not only assesses metallic materials but also examines the welds for compatibility with hydrogen passage. This comprehensive evaluation allows Saipem to determine the suitability of pipelines for hydrogen transportation, laying the groundwork for scalable and efficient methodologies in the future. With a legacy of 65 years in offshore activities related to hydrocarbon transportation, Saipem's foray into hydrogen pipeline construction signifies its commitment to innovation and sustainability. The recent certifications from RINA validate Saipem's capabilities in designing, constructing, and installing pipelines for safe and reliable hydrogen transportation. These certifications not only enhance Saipem's credibility but also open doors for further advancements in the field of subsea hydrogen infrastructure.
