Hydrogen-induced degradation of offshore steels in ageing infrastructure – models for prevention and prediction (HIPP)

The primary objective of HIPP is to develop a model framework which describes and couples environment-assisted hydrogen degradation mechanisms at different length and time scales towards a predictive mechanism-based integrity assessment approach for oil and gas steel infrastructure.

In the project HIPP we develop a model framework which describes and couples environment-assisted hydrogen degradation mechanisms at different length and time scales towards a predictive mechanism-based integrity assessment approach for oil and gas steel infrastructure.
