    • Quantifying Icebreaker Performance in Ice Management Operations by High-Fidelity Numerical Simulations 

      Bjørnø, Jon; van den Berg, Marnix; Lu, Wenjun; Skjetne, Roger; Lubbad, Raed; Løset, Sveinung (Chapter, 2020)
      In the study presented in this paper, the problem of quantifying the performance of icebreaker operations within ice management (IM) has been targeted, using the capabilities of high-fidelity simulations by a discrete ...

    • Review of wave-ice interaction studies 

      Li, Hongtao; Lubbad, Raed; Monteban, Dennis (Chapter, 2018)
      In the past several decades, sea-ice cover in the Arctic Ocean advances later than usual in the autumns and retreats earlier in the springs due to climate change. Concomitantly, total area of ice cover reduces and average ...

    • Sentinel-1 sar observations of peak wavelength and dominant wave direction in the marginal ice zone of the barents sea 

      Monteban, Dennis; Lubbad, Raed; Johnsen, Harald (Journal article; Peer reviewed, 2019)
      Synthetic aperture radar (SAR) has proven to be a very important source of data in the Polar regions because it covers large areas continuously, independent of the weather and time of day. In this study, we make use of ...

    • Simulator for Arctic Marine Structures (SAMS) 

      Lubbad, Raed; Løset, Sveinung; Lu, Wenjun; Tsarau, Andrei; van den Berg, Marnix (Chapter; Peer reviewed, 2018)
      As offshore activities in the Arctic constitute a relatively new field with only a handful of relevant operations to draw experience from, and since full-scale trials are extremely expensive, there is an expressed need for ...

    • Splitting as a Load Releasing Mechanism for a Floater in Ice 

      Lindseth, Sverre Haug (Master thesis, 2013)
      This master thesis divided into three parts: 1) A literature review on available literature concerning ice, fracture mechanics and theories for splitting of ice floes; 2) The development of a robust criterion for determination ...

    • Stålkai som ro/ro-rampe 

      Vevatne, Jens Kristian S (Master thesis, 2014)
      Denne oppgaven handler om prosjektering av en kai i forbindelse med en havneutvidelse. Kaien skal fungere som en ro/ro-kai hvor det legges til rette for at lasten kan rulles på lasteskipet og rulles av på destinasjonen. ...

    • Systematic investigation of data analysis methods in wave-ice interaction problem 

      Li, Hongtao; Gedikli, Ersegun Deniz; Lubbad, Raed (Chapter, 2020)
      Wave climate and extent of ice cover in the Arctic ocean have changed significantly in recent decades. Concomitantly, interest in studying wave-ice interaction has rapidly increased in the last two decades. Laboratory-scale ...

    • Toward a holistic load model for structures in broken ice 

      Kim, Ekaterina; Lu, Wenjun; Lubbad, Raed; Løset, Sveinung; Amdahl, Jørgen (Journal article; Peer reviewed, 2015)
      Over the past decade we have seen an increase in marine operations in Arctic waters. Despite research and work on several offshore standards and ship rules, the ice loads on fixed and floating structures are not fully ...

    • The Value of High-Fidelity Numerical Simulations of Ice-Ship and Ice-Structure Interaction in Arctic Design with Informed Decisionmaking 

      van den Berg, Marnix Albert; Bjørnø, Jon; Lu, Wenjun; Skjetne, Roger; Lubbad, Raed; Løset, Sveinung (Chapter, 2022)
      Long-term changes in the climate lead to an increase of activities in the Arctic. Ships and structures operating in Arctic waters may encounter sea ice and must be designed to withstand the loads resulting from ice-ship ...
