    • AC Corrosion of Electrically Heated Pipelines 

      Solheim, Kristian Thinn; Høyer-Hansen, Martin; Lervik, Jens Kristian (ISOPE - International Offshore and Polar Engineering Conference. Proceedings;2017, Chapter; Peer reviewed, 2017)

    • AC Corrosion Tests of Carbon Steel, AlZnIn Anodes and 25Cr Duplex for Subsea Applications 

      Solheim, Kristian Thinn; Høyer-Hansen, Martin (Chapter; Peer reviewed, 2021)
      This paper presents results from AC corrosion tests on 25Cr duplex and cathodically protected carbon steel. The results show that the corrosion rate is independent of transfer current density (0-200 A/m2) and power frequency ...

    • AC Corrosion Tests on Materials for Electrically Heated Flowlines 

      Solheim, Kristian Thinn; Høyer-Hansen, Martin; Larsen, Magnus Hurlen; Iversen, Øyvind (ISOPE - International Offshore and Polar Engineering Conference. Proceedings;2018, Chapter; Peer reviewed, 2018)

    • Inclusion of Wire Twisting Effects in Cable Impedance Calculations 

      Gustavsen, Bjørn Alfred; Høyer-Hansen, Martin; Triverio, Piero; Patel, Utkarsh R. (Journal article; Peer reviewed, 2016)
      Cable-series impedance modeling is widely applied in electromagnetic transients simulations and power-loss calculations. The calculations are usually performed in a 2-D frame using the finite-element method or alternative ...

    • Optimisation of power cable ampacity in offshore wind farm applications 

      Høyer-Hansen, Martin; Hellesø, Svein Magne; Solheim, Kristian Thinn; Mehammer, Eirill Bachmann; Eberg, Espen; Pedersen, Per Atle (Peer reviewed; Journal article, 2022)
      Inter-array power cables are used to connect wind turbines to the collector and export cable. In the transition from turbine tower to sea, the cable is installed in a J-tube, which has an unfavourable thermal environment ...

    • Trace heating of wet insulated subsea flowlines 

      Solheim, Kristian Thinn; Høyer-Hansen, Martin (ISOPE - International Offshore and Polar Engineering Conference. Proceedings;33, Chapter; Peer reviewed, 2023)
      This article evaluates flow assurance by heat trace cables for wet insulated flowlines as an alternative to direct electrical heating or chemicals. Heat trace cables are attractive for their simple and flexible design and ...

    • Voltages and AC Corrosion on Metallic Tubes in Umbilical Cables Caused by Magnetic Induction From Power Cable charging Currents 

      Gustavsen, Bjørn Alfred; Høyer-Hansen, Martin; Hatlo, Marius; Midttveit, Steinar (Journal article; Peer reviewed, 2018)
      Offshore umbilical cables often include both power cables and elements such as metallic tubes and signal cables. It was concluded from a recent failure of stainless tubes that AC corrosion was the failure cause. This paper ...
