(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-14)With the aim of reducing the travel time of the coastal highway E39 by substituting ferries with bridges and tunnels, the National Public Road Administration project “Ferry Free E39” includes several fjord crossings demanding ... -
Dynamic analysis and validation of a multi-body floating wind turbine using the moving frame method
(Peer reviewed; Journal article, 2023)This research applies the moving frame method (MFM) to the multi-body dynamic analysis of an OC3 phase IV spar buoy with the NREL 5MW turbine. Further, it verifies previous results obtained through numerical comparisons ... -
Dynamic analysis for the installation of offshore wind turbine foundations
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)This report looks into the possibility for using modified phased out shuttle tankers to install jacket foundations for offshore wind turbines. New massive wind mill farms are now being planned out in water depths of 40 ... -
Dynamic Analysis of a Floating Fish Cage with Feeding Systems
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06)Aquaculture is one of the fastest growing industries in Norway, and one of the fastest growing food production industries in the world. Limited access to available locations along the coast is gradually forcing aquacultural ... -
Dynamic analysis of a suspension bridge
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)This master thesis is the final part of my Master degree in structural and material science at the University of Stavanger. The thesis consists of collecting and studying data for the Lysefjord Bridge in light of the ... -
Dynamic analysis of a two-rotor wind turbine on spar-type floating platform
(Peer reviewed; Journal article, 2021-07)The dynamic response of a two-rotor wind turbine mounted on a spar-type floating platform is studied. The response is compared against the baseline OC3 single-rotor design. Structural design shows how the two-rotor design ... -
