    • Case study of a large-scale solar and wind power hybrid system at Fakken Wind Farm, Troms 

      Tiller, Charlotte (Master thesis; Mastergradsoppgave, 2017-06-01)
      The objective of this thesis is to investigate the feasibility of a large scale hybrid system at Fakken, Troms. There is already an existing 54 MW wind farm at site. The wind farm has considerably higher power production during winter compared to summer, and the electricity grid is therefore not fully exploited during summer. Adding a solar panel utility to the site could be a solution to this issue. ...

    • Constraining Transient Climate Response Using the Historical Temperature Record 

      Tranås, Olaf Lehn (Master thesis; Mastergradsoppgave, 2018-06-01)
      Anthropogenic greenhouse gas emissions alter the planet's energy balance and cause heating of the surface and oceans. Estimates of the implications of continued emissions are necessary to assess the severity of the situation. The transient climate response (TCR) is a measure of the climate's response to a continued increase in CO2 concentration, and indicates how much the temperature will increase ...

    • Evaluation of probability of failure of static equipment in pressurized mud systems on an offshore drilling installation 

      Rød, Bjarte (Master thesis; Mastergradsoppgave, 2015-06-01)
      Degradation of pressurized topside static mud equipment is a very complex process. Inspection is a helpful tool to monitor degradation and helps reduce the number of critical failures. If it is left undetected and unchecked, it can lead to leakage resulting in accidents. To set up an effective inspection program, the concepts of Risk-Based Inspection (RBI) can be utilized. RBI helps to develop an ...

      Fredriksen, Liv-Ellen (Master thesis; Mastergradsoppgave, 2018-06-15)
      The Arctic climate has changed considerably in the last few decades. Hence, a large fraction of the current studies of the Arctic climate relies on global atmospheric reanalyses, due to the shortage of meteorological observations in the Arctic. However, global climate models have shown to struggle with simulating the current conditions in the Arctic region. Thus, the objective of this thesis is to ...
