    • CO2 pipeline integrity: A coupled fluid-structure model using a reference equation of state for CO2 

      Aursand, Eskil; Aursand, Peder; Berstad, Torodd; Dørum, Cato; Hammer, Morten; Munkejord, Svend Tollak; Nordhagen, Håkon Ottar (Peer reviewed; Journal article, 2013)
      We present a coupled fluid-structure model to study crack propagation and crack arrest in pipelines. Numerical calculations of crack arrest, crack velocity and pressure profiles have been performed for steel pipes with an ...

    • CO2 pipeline integrity: A new evaluation methodology 

      Berstad, Torodd; Dørum, Cato; Jakobsen, Jana Poplsteinova; Kragset, Steinar; Li, Hailong; Lund, Halvor; Morin, Alexandre; Munkejord, Svend Tollak; Mølnvik, Mona Jacobsen; Nordhagen, Håkon Ottar; Østby, Erling (Peer reviewed; Journal article, 2011)
      A coupled fluid-structure model for pipeline integrity simulations has been developed. The pipe material and fracture propagation have been modelled using the finite-element method with a local fracture criterion. The ...

    • CO2 Pipeline Integrity: Comparison of a Coupled Fluid-structure Model and Uncoupled Two-curve Methods 

      Aursand, Eskil; Dørum, Cato; Hammer, Morten; Morin, Alexandre; Munkejord, Svend Tollak; Nordhagen, Håkon Ottar (Peer reviewed; Journal article, 2014)
      One challenge in CCS is related to the prevention of running-ductile fracture in CO2-carrying pipelines. Commonly used tools for ensuring crack arrest in pipelines hinge mainly on semi-empirical models, which may not be ...
