Course description
The transition of pipeline infrastructure toward low-carbon energy systems requires technically robust decisions on the transportation of hydrogen, ammonia and carbon dioxide. These fluids cannot be treated as simple substitutions for conventional natural gas or liquid hydrocarbon service. Each introduces specific design, materials, fracture, corrosion, inspection, operational and regulatory requirements that must be addressed before new construction, conversion, uprating or continued service can be justified.
This training programme provides a structured technical review of pipeline systems used for hydrogen, ammonia and CO2 transportation. The emphasis is placed on pipeline integrity, material compatibility, damage mechanisms, inspection requirements, requalification of existing assets, and the practical use of current international standards. The programme reflects recent developments in the ASME B31, EN, ISO and DNV frameworks, including the 2024 revision of EN 1594, the 2025 editions of ASME B31.4, ASME B31.8 and ASME B31.8S, ISO 13623:2017/Amd 1:2024, ISO 27913:2024, and the introduction of DNV-RP-F123:2026 for hydrogen pipeline systems.
For hydrogen pipelines, the programme addresses dedicated hydrogen systems and the conversion of natural gas infrastructure. Particular attention is given to hydrogen embrittlement, hydrogen-assisted fatigue crack growth, fracture mechanics, material traceability, weld integrity, pressure cycling, leak detection and integrity-management requirements. The programme also covers the practical differences between ASME B31.12, ASME B31.8, ASME B31.8S, EN 1594:2024, EN 12007 and supporting ISO/DNV guidance.
For ammonia transportation, the programme focuses on the use of ammonia as an energy carrier and on the integrity risks associated with liquid ammonia pipeline systems. The technical treatment includes ASME B31.4 application, liquid ammonia stress corrosion cracking, material selection, weld residual stress, cooling and pumping requirements, toxic release considerations, terminal interfaces and inspection planning.
For CO2 transportation, the programme distinguishes gaseous, dense-phase and supercritical operating envelopes. The technical treatment includes ASME B31.4, ISO 27913:2024, DNV-RP-F104, CO2 stream quality, impurities, water control, corrosion, decompression behaviour, running ductile fracture, fracture arrest, emergency response and requalification of existing pipeline systems for CCUS applications.
The programme is intended for pipeline, inspection, corrosion, materials, asset integrity, NDT, regulatory and project professionals who require an up-to-date technical framework for evaluating pipeline systems in the energy transition. The focus is on practical engineering decisions, current standard requirements, credible damage mechanisms and integrity-management methods.
