    • Effect of wave-current interaction on a long fjord-crossing floating pontoon bridge 

      Dai, Jian; Abrahamsen, Bjørn Christian; Hansen Viuff, Thomas; Leira, Bernt Johan (Peer reviewed; Journal article, 2022)
      Fjord-crossing floating bridges are sophisticated structures subjected to complex environmental loadings including combined action of wave and current. However, the effect of wave-current action is often neglected in a ...

    • Hydroelastic response of concrete shells during impact on calm water 

      Abrahamsen, Bjørn Christian; Grytten, Frode; Hellan, Øyvind; Søreide, Tore H.; Faltinsen, Odd Magnus (Peer reviewed; Journal article, 2023)
      Many ocean structures located offshore are supported by large vertical concrete columns. High and steep storm waves – in the process of breaking – may induce large local slamming loads on these columns. The present work ...

    • Hydroelastic response of Froude scaled stiffened steel panels exposed to design-critical wave slamming 

      Abrahamsen, Bjørn Christian; Grytten, Frode; Andreassen, Erik; Hellan, Øyvind (Peer reviewed; Journal article, 2023)
      Stiffened steel panels of offshore ocean structures may experience violent wave impacts which needs to be accounted for in design. The slamming pressures are often measured in scaled wave tank tests and imposed on finite ...

    • LFCS Review report – Model testing Model testing of large structures in a wave basin 

      Abrahamsen, Bjørn Christian; Stansberg, Carl Trygve (SINTEF Ocean AS rapporter;OC2018 A-073 - WP5, Research report, 2019-03-18)
      This document describes previous model tests on large structures in general and long pontoon bridges in particular. Furthermore, this report highlights the challenges related to model testing of these type of structures. ...

    • Study of an Entrapped Air Pocket due to Sloshing Using Experiments and Numerical Simulations 

      Firoozkoohi, Reza; Abrahamsen, Bjørn Christian; Faltinsen, Odd Magnus (ASME Proceedings | Offshore Technology;OMAE2017-62390, Chapter, 2017-09)
      The capability of the OpenFoam software to model slamming where air is entrapped between the free surface and the structure is investigated. The test case studied is a previously studied phenomenon, where an air pocket is ...
