Challenge

Lack of reliable and efficient tool for evaluating the performance of CRAs with respect to their susceptibility to sulphide stress cracking (SSC)

Solution

  • Modeling tool to understand and predict the electrochemical parameters that can be used to evaluate the susceptibility of super martensitic steels to SSC in sour environment
  • Guidelines and technique on evaluate the SSC susceptibility of super martensitic steels in sour environment

Benefits

  • Provide a predictive tool for materials performance evaluation
  • Provide a quantitative measure of the material susceptibility to SSC which in turn helps better define the environmental limits
  • Reduce the project specific testing effort

Value

Successful launch of this JIP will further improve DNV GL’s leading position in material selection and evaluation for challenging oil and gas production environment.
