      Fiskeri- og havbruksnæringens forskningsfond (FHF) ønsket å gjennomføre et forskningsprogram for å arbeide med utvalgte sider av rømmingsproblematikken. Spesielt viktig for FHF var det å fokusere på de viktigste årsakene ...

    •  Simulation of TDP Dynamics during S-laying of Subsea Pipelines 

      Hong, Wei (Master thesis, 2010)
      During the past one and a half decade, pipeline has been proven to the most economical means of large scale overland transportation for crude oil, natural gas and other products. At the same time, more and more problems ...

    • Wave induced effects on floaters of aquaculture plants 

      Kristiansen, David (Doctoral Theses at NTNU, 1503-8181; 2010:20, Doctoral thesis, 2010)
      The main objective of this work is to study wave loads on floaters of fish farms. Several incidents of major fish escapes due to structural collapse of fish farms in harsh weather have motivated this study, as a step towards ...

    • Underreporting of maritime accidents to vessel accident databases 

      Hassel, Martin (Master thesis, 2010)
      Underreporting of maritime accidents is a problem not only for authorities trying to improve maritime safety through legislation, but also to risk management companies and other entities using maritime casualty statistics ...

    • Analysis of accidental iceberg impacts with membrane tank LNG carriers 

      Myhre, Stine Aas (Master thesis, 2010)
      The probability of ship-iceberg impacts are increasing due to increasing production and due to more transportation routes near arctic areas. The first part of this thesis is an introduction to Liquefied Natural Gas (LNG) ...

    • Marine Machinery Systems - Tools and Architecture 

      Sandbakken, Egil Christoffer (Master thesis, 2010)
      The thesis presents tools and architecture regarding design of marine MSs in OSVs. It enlightens important aspects regarding the design based on a research study, and proposes a design methodology consisting of tools and ...

    • Wind Turbine Propulsion of Boats and Ships 

      Bøckmann, Eirik (Master thesis, 2010)
      Increasing focus on reduction of CO2 emissions, and the possibility of future severe shortage of oil have sparked renewed interest in wind as supplementary propulsion of merchant ships. Several alternative solutions are ...
