Saipem has been recognized by the classification society RINA with two certifications for its innovative performance qualification methodology concerning the materials utilized in constructing subsea pipelines for transporting gaseous hydrogen. The development of a protocol by Saipem has become essential due to the potential risks associated with using converted or newly built pipelines for hydrogen transportation, which could lead to material weakening. This protocol aims to evaluate the performance of metallic materials and welds with regards to the passage of hydrogen, ensuring the integrity and safety of the pipelines. By receiving approval in principle and technology qualification from RINA, Saipem has gained the necessary endorsement to continue its qualification processes and implement scalable methodologies. These certifications are pivotal in enabling Saipem to assess the compatibility of hydrogen pipelines during both the planning and operational phases, ensuring a secure and efficient infrastructure for hydrogen transport. Overall, this recognition marks a significant advancement in the field of hydrogen transportation, emphasizing the importance of thorough material qualification for the success of such projects.
