Background. Hydrogen Induced Cracking (HIC) / Stress Oriented Hydrogen Induced Cracking (SOHIC) is the process of hydrogen forming metals becoming brittle as a result of the diffusion mechanisms of hydrogen into the microstructure of steel structures.
Course Description. Background. Steels used in offshore flowlines, pipelines and risers are susceptible to corrosion fatigue in the presence of hydrogen sulfide (H2S) and moisture present in oil and gas production fluids.
Background. To ensure safety of any engineering system so that human life is protected and the environment is safe it is logical to be able to define when it is operating outside of its design condition.
