    • Objektiv metode for dokumentasjon av støtskader på laks 

      Steinke, Damian (Master thesis, 2021)
      I denne masteroppgaven ble det gjort et forsøk på å etablere en objektiv metode for å dokumentere hvilke effekter støt mot oppdrettslaks har for fiskehelse og -velferd. En oppdrettslaks opplever fysiske støt i rørsystemene ...
    • Oblique Loading of Aluminium Crash Components 

      Reyes, Aase Gavina R. (Dr. ingeniøravhandling; 2003:15, Doctoral thesis, 2003)
      The structural behavior of thin-walled aluminum extrusions, with and without aluminum foam filler, subjected to oblique loading was studied through experiments and numerical analyses. Extrusions similar to the ones tested ...
    • Oblique waves on a vertically sheared current are rotational 

      Ellingsen, Simen Andreas Ådnøy (Journal article; Peer reviewed, 2016)
      In the study of surface waves in the presence of a shear current, a useful and much studied model is that in which the shear flow has constant vorticity. Recently it was shown by Constantin (2011) that a flow of constant ...
    • Observasjons-ROV til Kystverket. 

      Skår, Morten Erling Strandman; Hellebostad, Christian Myklebust; Hellebostad, Anders Myklebust; Pedersen, Martin Strøm; Kvalsvik, Stephen Vegard Tarev; Øwre, Linn Kristin; Dittmann, Christian (Bachelor thesis, 2016)
      Hensikten med denne oppgaven er å utvikle et konsept til en kompakt og bærbar observasjons-ROV som kan bistå Kystverket med å inspisere sjømerker. ROV-en skal være lett å manøvrere, slik at inspeksjon og dokumentasjon kan ...
    • Observation of surface wave patterns modified by sub-surface shear currents 

      Smeltzer, Benjamin Keeler; Æsøy, Eirik; Ellingsen, Simen Andreas Ådnøy (Journal article; Peer reviewed, 2019)
      We report experimental observations of two canonical surface wave patterns – ship waves and ring waves – skewed by sub-surface shear, thus confirming effects predicted by recent theory. Observed ring waves on a still surface ...
    • Observations and Numerical Simulation of Icebergs in Broken Ice 

      Yulmetov, Renat (Doctoral theses at NTNU;2017:24, Doctoral thesis, 2017)
      Sea ice and icebergs are the major challenges for offshore activities in the Arctic. Design loads for Arctic offshore structures may be significantly reduced if the drift of sea ice and icebergs is possible to forecast ...
    • Observations from hydrodynamic testing of a flexible, large-diameter monopile in irregular waves 

      Bachynski, Erin Elizabeth; Thys, Maxime; Hoseini Dadmarzi, Fatemeh (Peer reviewed; Journal article, 2020)
      As the offshore wind industry moves toward larger wind turbines and deeper water, wave-induced loads on large-diameter monopiles are of increasing importance for ultimate limit state design checks. The combination of a ...
    • Observations of preferential summer melt of Arctic sea-ice ridge keels from repeated multibeam sonar surveys 

      Salganik, Evgenii; Lange, Benjamin Allen; Katlein, Christian; Matero, Ilkka; Anhaus, Philipp; Muilwijk, Morven; Høyland, Knut Vilhelm; Granskog, Mats (Peer reviewed; Journal article, 2023)
      Sea-ice ridges constitute a large fraction of the total Arctic sea-ice area (up to 40 %–50 %); nevertheless, they are the least studied part of the ice pack. Here we investigate sea-ice melt rates using rare, repeated ...
