    • Thermal and Mechanical Properties of SK One Component Polyurethane (SKOCP). Determining the Thermal and Mechanical properties of SKOCP in Colder Conditions 

      Eidesen, Hans-Kristian Norum (Master thesis; Mastergradsoppgave, 2017-05-30)
      Polymers have an extreme wide range of potential applications. From artificial heart valves, computer hardware, coating materials, noise damping materials and so on. Polyurethane is one of the such materials with a broad range of applications. A few such applications and properties are, but not limited to, treatment of leakage of an expansion joint, abrasion resistance, anti-freezing performance and ...

    • Thermal properties of neoprene and natural rubber in wetsuits 

      Busvold, Mads H. (Master thesis; Mastergradsoppgave, 2023-06-02)
      Surfers have concurred some of the harshest regions of the world with their surfboard, like the arctic waves of Norway. This is only made possible due to the wetsuit, a critical piece of equipment that enables surfers to stay in frigid waters and temperatures for hours. To understand the thermal behavior of wetsuits, knowledge on the phenomenon of heat transfer, and especially the conductive ...

    • Thermography and tensile tests of steel samples. Study of material properties and internal friction effects 

      Stange, Even (Master thesis; Mastergradsoppgave, 2018-06-01)
      The thesis presents analysis of material properties and internal effects in steel samples, with varying temperatures. Uniaxial tensile tests were conducted in both room temperature and low temperatures, to generate graphical measures of the mechanical properties. The steel samples were monitored with thermography throughout the course of the tensile tests, to investigate the heat generation associated ...

    • Towing of Floating Wind Turbine Systems 

      Jayachandran Nair, Rohith (Master thesis; Mastergradsoppgave, 2020-07-11)
      Towing is an important marine operation and floating wind turbines are the new way forward in our ever-expanding need for energy. In offshore floating wind turbine installation process, transport is an important phase. Presently, the turbines are assembled on shore and then towed to the installation spot one at a time. In this thesis, the theory behind the towing operation, modelling and simulation ...

    • Training of seafarers working on ships operating in polar waters 

      Pedersen, Martine Maria (Master thesis; Mastergradsoppgave, 2022-01-11)
      The aim of this thesis is to identify the competence gaps for seafarers who sail in polar waters have after completing the existing training courses based on the Polar Code. The best way to protect the environment and people in the Polar regions is by increasing the knowledge and competence of the people working in the vulnerable regions to ensure they make the best possible decisions and avoid ...

    • UAV as an inspection tool for power lines in Troms: Assessment of UAVs as a viable alternative to already established methods for inspection of power lines. 

      Ubeda-Nordnes, Jonathan (Master thesis; Mastergradsoppgave, 2018-06-02)
      Power line inspection is one of the most important things in a modern society, and therefore it is important that it be kept in a functional state. Because of this, many methods are used to keep it that way. There are many factors to consider before using UAVs as a viable alternative to already established methods. Factors such as robustness against harsh weather, limits to its range and battery ...

    • Upgrading technologies for biogas production plants. Overview and life cycle cost analysis of available technologies 

      Brendeløkken, Hanne Wasmuth (Master thesis; Mastergradsoppgave, 2016-06-01)
      An increased focus on waste management has emerged during the last decade. Renewable energy, efficient energy usage and cuts in greenhouse gas emissions are highly prioritized by the EU. The International Energy Agency (IEA) and the World Energy Council estimates that the global energy demand will grow within the next decades. The continuously increasing energy demand, contributes to development of ...

    • Utfordringer ved snøkrabbefangst med hensyn på risiko ved operasjoner på sjøen. Kartlegging av risiko og risikoreduserende tiltak 

      Jørgensen, Andreas (Master thesis; Mastergradsoppgave, 2016-05-31)
      Sentrale organer innenfor norsk fiskeri har de siste årene kartlagt spredning av arten ”Chionoecetes Opilio”, snøkrabbe, til norske farvann. Bestanden av snøkrabbe kommer fra russisk side av delelinjen i Barentshavet, og sprer seg vestover til norske territorialfarvann. Norsk havforskningsinstitutt mener at krabben kommer til å etablere seg i Svalbardsonen de kommende år. Krabben anses å være ...

    • Vessel operations in relation to new types of offshore aquaculture facilities, and weather windows in exposed areas 

      Kristiansen, Elise (Master thesis; Mastergradsoppgave, 2022-06-01)
      The marine aquaculture industry is expanding the production into new sea areas. The technology is advancing, and offshore aquaculture facilities are being developed. The offshore developments can offer significant benefits that applies to the economy, optimization of operations and production, as well as minimizing the impact on the coastal areas. Structural and operation procedures need to be ...

    • Well Testing in the Barents Sea. Risk Analysis; Methods and Procedures 

      Mathisen, Espen Heiskel (Master thesis; Mastergradsoppgave, 2014-06-01)
      The thesis is done in co-operation with DNV GL Harstad and Schlumberger. DNV GL has provided access to historical accidents data, by using technical documents. Schlumberger has provided technical information about well testing and hazards related to such an event, and an internal risk analysis document, which they use in their operations. This document is modified to suit, and account, for arctic ...

    • Wind Chill Effect & Thermal Insulation. Study of Wind Chill Effect and Thermal Insulation using Infrared Imaging 

      Ahmad, Tanveer (Master thesis; Mastergradsoppgave, 2017-05-15)
      Wind chill factor is explained as the cooling sensation due to the exposure of wind temperature environment. The wind chill factor depends on air temperature, wind velocity, and humidity. Wind chill poses serious health risks. Various wind chill index models are given in the literature. In order to understand the wind chill effect, it is important to understand the phenomenon of heat transfer. There ...
