• Column slamming loads on a TLP from steep and breaking waves 

      Vestbøstad, Tone M.; Økland, Ole David; Lian, Gunnar; Stavang, Terje Peder (Journal article; Peer reviewed, 2017-06-25)
      Previous model test campaigns of various large-volume platforms indicate that wave impact loads on vertical platform columns can become high in extreme sea states. Column slamming is a highly non-linear and complex problem ...
    • Dynamic responses of a jacket-type offshore wind turbine using decoupled and coupled models 

      Ong, Muk Chen; Bachynski, Erin Elizabeth; Økland, Ole David; Passano, Elizabeth Anne (ASME Proceedings | Ocean Renewable Energy;OMAE2014-24246, Chapter, 2014-06)
      This paper presents numerical studies of the dynamic responses of a jacket-type offshore wind turbine using both decoupled and coupled models. In the decoupled (hydroelastic) model, the wind load is included through ...
    • Experimental study of floating bridge global response when subjected to waves and current 

      Hansen Viuff, Thomas; Ravinthrakumar, Senthuran; Økland, Ole David; Grytå, Ole Anton; Xiang, Xu (Journal article; Peer reviewed, 2023)
      The present paper investigates the wave- and current-induced responses of the Bjørnafjord phase 5 K12 floating bridge concept based on small-scale model tests. Due to the extensive length of the bridge concept combined ...
    • LFCS Review report - Environmental conditions Wind, wave and current in coastal areas 

      Fergestad, Dag; Økland, Ole David; Stefanakos, Christos; Stansberg, Carl Trygve; Croonenborghs, Eloïse; Eliassen, Lene; Eidnes, Grim (SINTEF Ocean AS rapporter;OC2018 A‐073 - WP1, Research report, 2018-07-12)
      A review is performed on the description of evironmental conditions in Norwegian coastal areas in relation to Large Floating Coastal Structures and the planning of long floating bridges across fjords. First, an outline of ...
    • Model test of a hydroelastic truncated floating bridge with a stay-cable tower 

      Hansen Viuff, Thomas; Ravinthrakumar, Senthuran; Økland, Ole David; Grytå, Ole Anton; Xiang, Xu (Journal article; Peer reviewed, 2023)
      Experimental studies of long offshore and coastal structures such as very long floating bridges are challenged by the combination of coastal wave environments with relatively small design waves and excessive structural ...
    • Model tests of a hydroelastic truncated floating bridge 

      Rodrigues, José Miguel; Hansen Viuff, Thomas; Økland, Ole David (Peer reviewed; Journal article, 2022)
      Literature on tank tests of floating bridges is extremely rare, while a very limited number of publications covering tests of other types of very large floating structures exist. Here, the authors share their experience ...
