    • Hydrodynamic Modeling of Tension Leg Platform Wind Turbines 

      Bachynski, Erin Elizabeth; Moan, Torgeir (Chapter, 2013)
      In order to compute the system response of tension leg platform wind turbines (TLPWTs), it is important to accurately capture the hydrodynamic loading not only at the wave frequency, but also in the low (difference) and ...

    • Hydrodynamic modelling and estimating response of a glacial ice near a drilling rig 

      Ommani, Babak; Berthelsen, Petter Andreas; Lie, Halvor; Aksnes, Vegard Øgård; Løland, Geir (Chapter, 2019)
      Impact scenarios involving a typical drilling rig and glacial ice are studied. The goal is to better identify the important physical effects in modelling the dynamics of glacial ice in presence of waves and a floating ...

    • Hydrodynamic Modelling Effects on Fatigue Calculations for Monopile Offshore Wind Turbines 

      Malik, Mohibb Ghani (Master thesis, 2016)
      For shallow and intermediate water depths, monopile foundations are the most commonly used concept, and is considered the most promising with respect to the cost of energy. The typical highest structural eigenperiods of ...

    • Hydrodynamic modelling of physical habitat conditions for fish in the Ekso river near Flatekval 

      Deng, QIqi (Master thesis, 2018)
      In this study, a 2D hydrodynamic model HEC-RAS is used to simulate the flood inundation, water depths and flow velocities of the river reach in the Eksingedal watercourse near Flatekval in western Norway. The objectives ...

    • Hydrodynamic optimization of bulk and tank ship hulls 

      Utby, Haakon (Master thesis, 2016)
      International shipping transports more than 80 percent of global trade. Traditionally bulk carriers have been built to minimize construction cost and maximize cargo-carrying capacity, neglecting hydrodynamic characteristics. ...

    • Hydrodynamic Optimization of Trimaran Workboat Hulls 

      Kursetgjerde, Andrea Marie Schmedling (Master thesis, 2017)
      The object of this master thesis was to perform an initial design optimization for a trimaran concept, with the goal of minimizing the hydrodynamic resistance for a speed of 30 knots. The thesis is written in cooperation ...

    • Hydrodynamic optimization of wetland restoration measures at the Storelva river floodplain with its meanders and oxbow lakes in Southern Norway 

      Lulla, Florian (Master thesis, 2019)
      The “Fellesprosjektet Ringeriksbanen og E16” is an infrastructure project in the south of Norway connecting Oslo and shortening the travel time with the new housing and develop-ment area of Ringerike. For the connection ...

    • Hydrodynamic performance of sail-assisted merchant vessels 

      Kramer, Jarle Andre (Master thesis, 2014)
      The main goal of this project was to explore the different physical effects that are involved when a ship is using the technology of wing sails as propulsion. The wing sails can provide a lot of thrust, but they also create ...
