• Bending and buckling of internally-pressurized steel lined pipes 

      Gavriilidis I., Karamanos S.A. (2019)
      During offshore installation, steel lined pipes are subjected to severe plastic bending, resulting in detachment of the thin-walled liner pipe from the outer pipe and eventually, the formation of local buckling in the form ...
    • Effect of Manufacturing Process on Lined Pipe Bending Response 

      Gavriilidis I., Karamanos S.A. (2020)
      The effects of manufacturing process on mechanically lined pipe structural performance are investigated. Alternative manufacturing processes are considered, associated with either purely hydraulic or thermo-hydraulic ...
    • Influence of lined pipe fabrication on liner wrinkling 

      Gavriilidis I., Karamanos S.A. (2019)
      An economical method to protect offshore pipelines against corrosive ingredients of hydrocarbons is a double-walled (also called “lined” or “bi-metallic”) pipe, in which a thick-walled low-alloy carbon steel (“outer pipe”) ...
    • Liner wrinkling in offshore steel lined pipes during reeling installation 

      Gavriilidis I., Karamanos S.A. (2021)
      A three-dimensional numerical model of a mechanically bonded lined pipe is developed, simulating its structural response during the reeling installation method. An installation/failure–repair scenario is considered with ...
    • Structural response of steel lined pipes under cyclic bending 

      Gavriilidis I., Karamanos S.A. (2022)
      Motivated by reeling installation of mechanically-lined offshore steel pipes, the present paper investigates the structural performance of a bi-material lined pipe under cyclic bending, using advanced finite element tools. ...
