A strong and valuable programme under construction with key topics at EUROCORR 2025👌
Norwegian Corrosion Society | Norsk Korrosjonsteknisk Forening and EFC - European Federation of Corrosion are honored to present Vigdis Olden as a Keynote Speaker at EUROCORR 2025. Vigdis Olden is a senior research scientist at SINTEF Industri in Trondheim, Norway. Her main field is hydrogen embrittlement of metallic materials. She is working in a research group where a large part of the project portfolio is related to the structural integrity of subsea infrastructure in oil and gas, including hydrogen. Presentation Overview Since the late 1990s, hydrogen embrittlement in Norwegian subsea infrastructure for natural gas transport, caused by hydrogen from cathodic protection, has posed significant challenges for pipeline operators and energy companies. Through intensive research and development, the industry has learned to manage and mitigate these issues, incorporating the acquired knowledge into design and operational guidelines. Currently, the industry is exploring the feasibility of repurposing this subsea infrastructure for 100% hydrogen gas transport. The existing Norwegian pipeline network spans 8,900 km and is primarily constructed from higher strength steel than onshore pipelines, making it more susceptible to hydrogen embrittlement. These pipelines are also designed for different loads and operating environments compared to onshore pipelines. The anticipated operating pressures and purity of hydrogen gas in the Norwegian subsea network are 150-200 bar and 100% hydrogen, respectively, which are higher than those in existing hydrogen pipelines. Since 2019, SINTEF has been conducting the HyLINE I and HyLINE II projects to establish fundamental knowledge about the effects of hydrogen gas on pipeline steels and their weldments, aiming to enable the safe and efficient use of both existing and new subsea pipeline infrastructure. The research topics include hydrogen uptake and diffusion, nano- and micro-mechanical characterization, fracture toughness and fatigue, as well as numerical modeling for fracture assessment. A summary of key findings within these research areas and their interconnections will be presented. Register here - https://lnkd.in/dAJfBY8V We are looking forward to September 2025, see you there!
