Designing facilities for CO2 transport and injection requires a thorough analysis of the relevant degradation modes. This includes such effects as wet upsets in nominally "dry" CO2, running ductile fracture in CO2 fluid, stability of elastomers and low temperatures associated with CO2 depressurization. If existing facilities are to be used, an assessment of their integrity status with a view to CO2 service has to be performed as well. A case involving such an analysis is described. Next to internal corrosion and low temperature embrittlement, specific aspects considered are: effect of impurities in CO2 running fracture of the export pipeline internal epoxy flow coating stability valve material compatibility with CO2 well completion aspects Materials selection and corrosion control to mitigate potential threats to integrity are summarized. The work provides an outline of a framework that can serve to manage integrity in operation.
