• Finite Element Implementation of Fibre-Reinforced Materials Model in Abaqus/Explicit 

      Vestrum, Ole (Master thesis, 2015)
      This thesis is concerned with the constitutive modelling of short fibre-reinforced composites in the finite element code Abaqus/Explicit. The model is presented as a generic framework which is based on a two-phase ...
    • Finite element modeling of porous polymer pipeline coating using X-ray micro computed tomography 

      Vestrum, Ole; Langseth, Magnus; Børvik, Tore (Journal article; Peer reviewed, 2019)
      Offshore pipelines are designed to sustain impact from fish trawl equipment and anchors, but due to component complexity, insulating coating solutions are often neglected in mechanical capacity estimates. In this work, ...
    • Impact against coated offshore steel pipes 

      Kulsrud, Eirik Bugge; Hammersvik, Steffen (Master thesis, 2017)
      This thesis is part of an ongoing research program between SIMLab and Statoil about impacts on coated offshore pipelines. Impact loads may occur from objects such as anchors or trawls, causing severe damage to the pipe ...
    • Mechanical behaviour of sacrificial sandwich panels 

      Bengtson, Olav Ingvaldsen (Master thesis, 2016)
      The main objective of this thesis is to conduct a numerical study of aluminium foam core sacrificial sandwich panels in order to understand how different parameters affect the energy absorption when subjected to various ...
    • Mechanical modeling of the polymeric coating on a subsea pipeline 

      Vestrum, Ole; Langseth, Magnus; Børvik, Tore (Chapter, 2019)
      Offshore pipelines may be exposed to a range of extreme loading situations during operation on the seabed such as impact by trawl gear or anchors. While not primarily being designed for it, thermal insulating polymeric ...
    • Quasi-static and dynamic indentation of offshore pipelines with and without multi-layer polymeric coating 

      Vestrum, Ole; Kristoffersen, Martin; Polanco-Loria, Mario; Ilstad, Håvar; Langseth, Magnus; Børvik, Tore (Journal article; Peer reviewed, 2018)
      Offshore pipelines are occasionally subjected to accidental impact loads from trawl gear or anchors, which may damage the pipe. In this study, a series of indentation experiments carried out on offshore steel pipes covered ...
