Italian classification and marine engineering consultancy RINA has granted Saipem two certifications for their methodology in qualifying the performance of subsea hydrogen pipelines. One of the main challenges in transporting hydrogen through pipelines is the risk of material weakening. Saipem has responded by developing a protocol to assess the performance of metallic materials and welds in relation to the passage of hydrogen. This evaluation helps ensure the compatibility of pipelines during both the planning and operational stages. The Approval in Principle (AiP) and Technology Qualification certifications obtained from RINA are significant milestones in advancing innovative technologies and opening doors for further qualification processes. These certifications allow for the widespread adoption of Saipem's methodology in evaluating the performance of materials used in constructing subsea hydrogen pipelines, facilitating the transportation of gaseous hydrogen.
