    • Simulator Studies on the Effectiveness of a Collision Avoidance Display in True Motion 

      Grepne-Takle, Ruben (Master thesis, 2011)
      A major concern for the navigator during a voyage is collision avoidance. The IBS (Integrated Bridge System) has a large quantity of marine traffic data available. Complicated and congested traffic may challenge the ...
    • Coupling of marine riser and tensioner system 

      Olssøn, Tor Trainer (Master thesis, 2011)
      A coupled model of a marine riser and a tensioner system is built. The riser is modeled using the multi-body dynamics program MSC Adams, and the tensioner system using the powerful controls and systems simulation tool, MSC ...
    • Development of a DP system for CS Enterprise I with Voith Schneider thrusters 

      Skåtun, Håkon Nødset (Master thesis, 2011)
      A model ship named CS Enterprise 1 (CSE1) has been purchased by the Norwegian University of Science and Technology (NTNU) to be used for demonstrations and student experiments at the Marine Cybernetics Laboratory (MC ...
    • Decision Models related to Ageing and Life Extension 

      Mogstad, Therese (Master thesis, 2011)
      Ageing is a process in which the characteristics of a Structure, System or Component (SSC) gradually change with time or use. Several installations tied to the Norwegian petroleum industry are ageing. They have reached ...
    • Prediction of ice loads of an Arctic SPAR 

      Fjellvang, Heidi (Master thesis, 2011)
      Asubstantial amount of the world’s hydrocarbon deposits is assumed to be found in the Arctic. The Arctic region differs from other regions mainly due to the climate and presence of sea ice features. In order to minimize ...
    • High energy ship collisions with bottom supported offshore wind turbines 

      Ramberg, Henriette Flathaug (Master thesis, 2011)
      Offshore wind farming is an industry under development and involves challenges. The farms might be located close to ship trading routes. This increases the risk of ship-wind farm impact, causing economic losses, environmental ...
    • The importance of added resistance and speed of ships due to waves for ships designed for slow-steaming 

      Sunde, Carl Arthur (Master thesis, 2011)
      In the recent years the greenhouse effect in the atmosphere has become much stronger because of emissions of greenhouse gases on the earth. One of these gases is CO2. This may come from combustion of fossil fuel. The ...
    • Pipeline Accidental Load Analysis 

      Vervik, Stian (Master thesis, 2011)
      Ship interaction in terms of anchor hooking on a subsea pipeline has been investigated in this thesis. An attempt has been made to predict the most probable anchor interaction loads on the Kvitebjørn gas pipeline in the ...
    • Interaction between bodies in a viscous flow 

      Hovrud, Jan Marius (Master thesis, 2011)
      Using the open-source CFD-solver OpenFOAM with a numerical scheme which is first order in time and second order in space, calculations of unsteady 3D flow around two cylinders in tandem arrangement at low Reynolds number ...
    • System design for rapid cargo change on liquefied gas carriers 

      Vesterdal, Øyvind L. (Master thesis, 2011)
    • AIS Technology as Support for the Risk Picture in Naval Transport 

      Skollevold, Christian (Master thesis, 2011)
      This thesis investigates the feasibility of using AIS technology as a support for determining the risk picture in naval transport. Traffic data is gathered from the AIS interface and compared with accident data from NMD ...
    • Meshfree Least Square-based Finite Difference method in CFD applications 

      Sandnes, Pål Grøthe (Master thesis, 2011)
      Most commercial computational fluid dynamics (CFD) packages available today are based on the finite volume- or finite element method. Both of these methods have been proven robust, efficient and appropriate for complex ...
    • Mixing in the stratified interface of the Faroe Bank Channel overflow: the role of transverse circulation and internal waves 

      Seim, Knut Sponheim; Fer, Ilker (Journal article; Peer reviewed, 2011)
      The overflow of cold water across the Faroe Bank Channel sill is a significant volume flux of dense water to the North Atlantic Ocean. Using observations of hydrography, current and microstructure from a 1 week cruise and ...
