How you'll learn
Fully 100% online training on the SEIUM campus, with downloadable material, recorded lessons and an assigned technical tutor. No fixed timetables: students progress at their own pace within the intake period, which makes it easy to combine with work.
Each module combines theory, guided reading of the original standard and applied exercises. The software used is HyRAM+, DNV Phast, FLACS, ALOHA, in free, academic or evaluation versions. Case studies draw on real procedures for ATEX zone classification at hydrogen refuelling stations, quantitative risk analysis of leaks, and review of filling protocols at 350 and 700 bar. Assessment is continuous across each module, plus the final integrative project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Describe the hydrogen properties relevant to safety.
Analyse the risks of storage at 350 and 700 bar.
Explain refuelling protocols and their temperature and pressure limits.
Identify the specific risks of liquid hydrogen.
Apply qualitative and quantitative risk analysis methodologies.
