  • Finite element analysis of materials for aquaculture net cages. FEA of materials for aquaculture net cages using ANSYS Workbench 

    Myrli, Odd Einar Lockertsen (Master thesis; Mastergradsoppgave, 2017-06-20)
    The number of good sites in less exposed locations for aquaculture farming is limited. Trends are now that the fish cages are increasing in both width and depth as well as more weather-exposed locations are taken into use. As the net cages continues to increase in size, so does the material costs. The design of the sea cages should be modified for safe and reliable use in remote offshore locations. ...

  • Sikkerhetsvurdering av Tromsøysundtunnelen 

    Jensen, Sondre Finjord (Master thesis; Mastergradsoppgave, 2016-05-31)
    Veitunneler er statistisk sett en av de sikreste delene av veinettet, med svært få hendelser sammenlignet med det øvrige nettet. Det er derimot spesielle forhold som i vesentlig grad avviker fra veinettet for øvrig med tanke på brann og rømning. De ulike sikkerhetssystemene i tunnelen er med på å hindre at hendelser oppstår, og redusere konsekvensene hvis ulykken først er ute. Gjennom oppgaven ...
  • The application of unmanned aerial vehicles for snow avalanche search and rescue
