  • Preventing Atmospheric Icing in Aviation: Passive Repulsion of Super Cooled Water Droplets through Hydrophobic Nanocomposites 

    Hobitz, Gøran Frantzen (Master thesis; Mastergradsoppgave, 2020-07-13)
    The aviation industry already consists of a complex system of strict regulations related to operation and maintenance, where severe weather conditions further challenge flight operations. Recent research has shown that most aircraft accidents are caused by icing externally, where severe icing conditions lead to the critical degradation of the aerodynamic effectiveness – increasing the stall speed. ...
  • Limitations of Ice Accretion on Offshore Aquaculture Facilities 

    Marsden, Benjamin (Master thesis; Mastergradsoppgave, 2021-12-15)
    Sea spray icing is a constant risk for fish farms operating in cold climates, such as on the Northern Norwegian coast, and there must therefore exist methods to reduce this risk. This thesis discusses the consequences of ice accretion to the traditional plastic circular fish cage design, and how the cage reacts under the pressure of added mass from sea spray icing. The prediction of sea spray icing ...
  • Resilience, Reliability, and Recoverability (3Rs) 

    Jheeta, Manjit Singh (Master thesis; Mastergradsoppgave, 2022-01-06)
    Recent natural and human-made disasters, mortgage derivatives crises, and the need for stable systems in different areas have renewed interest in the concept of resilience, especially as it relates to complex industrial systems with mechanical failures. This concept in the engineering systems (infrastructure) domain could be interpreted as the probability that system conditions exceed an irrevocable ...

    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 ...
  • Roll motion on small traditional Norwegian fishing vessels 

    Kristiansen, Gøran (Master thesis; Mastergradsoppgave, 2021-08-09)
    Roll motion is one of the six degrees of freedom and is the most difficult to predict, as roll motion is extremely sensitive to the viscous effect and induced flow separation. The smaller fishing vessel fleet commonly operates in almost all weather conditions, and sometimes in remote areas with cold arctic water where rescue can be far away and difficult. The safety of fishers depends on the vessel's ...

  • Implementation and Control of an Inverted Pendulum on a Cart 

    Hanekam, Halvard (Master thesis; Mastergradsoppgave, 2021-05-28)
    An Inverted Pendulum on a Cart is a common system often used as a benchmark problem for control systems. The system consists of a cart that can move in one direction on the horizontal plane and a pendulum attached to the cart through a hinge point. The pendulum can rotate 360° on the plane made up of the vertical direction and the direction the cart can move. The system is controlled by applying a ...
  • Simulation of Meteorological and Oceanographic Parameters: An Application in Spray Icing Prediction 

    Shojaei Barjouei, Abolfazl (Master thesis; Mastergradsoppgave, 2020-07-13)
    Sea spray icing is considered as a major environmental challenge in the Arctic Ocean, which poses a critical risk not only to the vessels and industrial operations but also to human safety. Although some studies have been carried out to estimate spray icing rate (e.g., RIGICE04 and ICEMOD models), such models suffer from some unrealistic modeling assumptions and limited verification. Moreover, limited ...

    Waste incineration-based district heating plants in Norway struggle from energy efficiency drawbacks during the warmer months of the year from May - September due to the reduced demand in heating. As a result, thermal energy gets discarded to ambient air, which affects the energy efficiency of the plants. This study aims at presenting an overview of the waste incineration industry in Norway and ...
  • Study of failure profiles in the bridge structures 

    Amiri, Razieh (Master thesis; Mastergradsoppgave, 2019-10-15)
    Bridge safety is an indispensable part of transportation safety. However, each bridge is unique with respect to its material, design and the environment which it is located in, and other relevant factors. This makes defining a unified framework for studying and categorizing failures in the bridges a difficult task. The current report aims at taking the first step to reach such a goal. This report ...
