Hydrogen significantly influences fatigue life, showing critical effects on pipeline girth welds under high stress.
S-N curves from fatigue testing revealed reduced performance in hydrogen environments compared to air.
The study characterizes girth weld and base material performance, aiming to inform pipeline design against embrittlement.
These findings support safe offshore hydrogen transport, emphasizing the need for revised guidelines and standards.
