Tenaris will present initial findings from a study conducted in collaboration with IGI Poseidon, a joint venture between Greece’s DEPA International Projects and Italy’s Edison S.p.A., at the 17th OMC Med Energy Conference, held April on 8-10 in Ravenna, Italy.
Launched in 2024, the study involves fracture toughness testing of materials exposed to high-pressure hydrogen environments. The research focused on 22-inch welded pipe (DNV SAWL 485 FDU grade) and girth-welded joints subjected to H2 gas pressures of up to 330 bar.
By simulating worst-case scenarios, these tests validate material performance for offshore hydrogen transportation. Even at 330 bar, the examined materials maintained their fracture toughness with no additional loss compared to typical operating pressures. Results also showed consistent performance across different pipe sections, including the weld heat-affected zone and weld metal.
“Our strong collaboration with IGI Poseidon was instrumental in conducting these tests, which required significant efforts from all the parties involved. These findings mark an important step in the development of safe and efficient hydrogen infrastructure, supporting the expansion of offshore hydrogen pipelines as a key element of the global energy transition,” said Philippe Darcis, Tenaris Pipeline Technology Senior Director.
