    • Parallel channels' fracturing mechanism during ice management operations. Part I: Theory 

      Lu, Wenjun; Lubbad, Raed; Shestov, Aleksey; Løset, Sveinung (Journal article; Peer reviewed, 2018)
      It is frequently observed that long cracks in sea-ice tend to form between parallel channels during ice management operations. The long cracks that develop play an important role in reducing the size of the managed ice ...

    • Parallel channels' fracturing mechanism during ice management operations. Part II: Experiment 

      Lu, Wenjun; Lubbad, Raed; Løset, Sveinung (Journal article; Peer reviewed, 2018)
      During ice management operations, cutting parallel channels with narrow spacing in the ice using icebreakers can effectively reduce the size of ice floes reaching the protected vessel/structure. A narrow channel spacing ...

    • Performance Quantification of Icebreaker Operations in Ice Management by Numerical Simulations 

      Bjørnø, Jon; Skjetne, Roger; van den Berg, Marnix; Lu, Wenjun; Lubbad, Raed; Løset, Sveinung (Peer reviewed; Journal article, 2021)
      The paper addresses the problem of quantifying and assessing the effectiveness of icebreaker operations in ice management (IM) using a high-fidelity simulator. The numerical model includes an accurate geometric representation ...

    • Probabilistic methods for estimation of the extreme value statistics of ship ice loads 

      Chai, Wei; Leira, Bernt Johan; Næss, Arvid (Journal article; Peer reviewed, 2017)
      It is well known that when a ship sails in ice-covered regions, the ship-ice interaction process is complex and the associated ice loads on the hull is a stochastic process. Therefore, statistical models and methods should ...

    • A review of environmental impacts of winter road maintenance 

      Vignisdottir, Hrefna Run; Ebrahimi, Babak; Booto, Gaylord Kabongo; O'Born, Reyn Joseph; Brattebø, Helge; Wallbaum, Holger; Bohne, Rolf André (Peer reviewed; Journal article, 2019)
      The need for winter road maintenance (WRM) is changing in cold regions due to climate change. How the different modes of WRM will contribute to future overall emissions from infrastructure is therefore of great interest ...

    • Time-frequency analysis of acceleration data from ship-ice interaction events 

      Heyn, Hans-Martin; Skjetne, Roger (Journal article; Peer reviewed, 2018)
      During operations with ships in ice-infested waters, vibrations of the hull occur due to ship-ice interaction. The acting ice load and the induced vibrations depend on the ice regime and ice breaking mechanism. Especially ...
