    • Wave inhomogeneities in a wave basin of constant water depth 

      Lafleche, Sebastien Jacques Marie; Ommani, Babak; Kristiansen, Trygve; Fouques, Sebastien (Journal article; Peer reviewed, 2023)
      Experimental testing of large marine structures in hydrodynamic laboratories requires an accurate reproduction of waves over a large area of the basin. However, with a uniform motion of the wavemaker, wave interactions ...

      Brørby, Bjørn Theodor Torp (Master thesis, 2022)
      Denne masteroppgaven presenterer alternative metoder for bølgelastkompensasjon i dynamiske posisjonering (DP) av marine fartøy, der stabile og robuste konvensjonelle kontrollere med tilbakekopling vanligvis brukes. Slike ...

    • Wave load effect analysis of a floating bridge in a fjord considering inhomogeneous wave conditions 

      Cheng, Zhengshun; Gao, Zhen; Moan, Torgeir (Journal article; Peer reviewed, 2018)
      When designing a floating bridge crossing a deep and wide fjord, a homogeneous wave field is usually assumed for simplicity. However, waves in fjords are commonly inhomogeneous, and hence the mentioned design practice ...

    • Wave loads on decks of offshore structures in random seas 

      Kota, Ravikiran S (Doktoravhandlinger ved NTNU, 1503-8181; 2012:163, Doctoral thesis, 2012)

    • Wave Loads on Underwater Protection Covers 

      Havn, Jarle (Master thesis, 2011)
      Submerged structures in shallow water can be exposed to large hydrodynamic wave- and current forces. An estimate of the total external loads will be important for the design and robustness of the structures. The aim will ...

    • Wave power statistics for sea states based on wind statistics 

      Myrhaug, Dag (Journal article; Peer reviewed, 2018)
      The paper addresses how the wave power for sea states can be assessed based on available wind statistics for an ocean area. Results using a simple analytical tool are exemplified for a Pierson–Moskowitz wave spectrum ...

    • Wave propagation in multicomponent flow models 

      Flåtten, Tore; Morin, Alexandre; Munkejord, Svend Tollak (Journal article; Peer reviewed, 2010)
      We consider systems of hyperbolic balance laws governing flows of an arbitrary number of components equipped with general equations of state. The components are assumed to be immiscible. We compare two such models: one in ...

    • Wave propagation over rugged topography Mehamn Harbourentrance case study 

      TAEHUN, KIM (Master thesis, 2011)

    • Wave Propulsion of Ships 

      Bøckmann, Eirik (Doctoral thesis at NTNU;2015:16, Doctoral thesis, 2015)
      Propelling a boat forward by converting wave energy into propulsive thrust was first proposed in 1858 and first successfully done in practice in the 1890s - to the author's knowledge. Several experimenters have since ...

    • Wave Response Experiments of Fish Farms 

      van der Meij, Jesper (Master thesis, 2023)
      Den globale havbruksnæringen er i en fase med store expansjon. Bærekraftig vekst i havbrukssektoren er en flott mulighet til å sikre sunn mat for mange. Det krever strenge regler og forskrifter, som drar nytte av omfattende ...

    • Wave response of closed flexible bags 

      Lader, Pål; Fredriksson, David W.; Volent, Zsolt; DeCew, Jud; Rosten, Trond Waldemar; Strand, Ida Marlen (Journal article; Peer reviewed, 2017)
      Recent environmental considerations, as salmon lice, escape of farmed fish and release of nutrients, have prompted the aquaculture industry to consider the use of closed fish production systems (CFPS). The use of such ...

    • Wave runup and wave rundown estimation based on long-term variation of wind statistics 

      Myrhaug, Dag; Sunde, Tonje (Journal article; Peer reviewed, 2018)
      The paper presents a simple analytical method that can be used to estimate wave runup (RU) and wave rundown (RD) on shorelines and coastal structures for sea states based on long-term wind statistics. Eight different ...

    • Wave Runup and Wave Rundown on Shorelines and Coastal Structures Based on Long-Term Variation of Wind and Wave Conditions 

      Sunde, Tonje (Master thesis, 2017)
      In the resent years the fear of violent storms occuring more often, and with increasing violence, has drawn new attention to research on wave runup and wave rundown. Severe storm conditions could cause great damage on ...

    • Wave Slamming Forces on Offshore Wind Turbine Jacket Substructures 

      Tu,Ying (Doctoral theses at NTNU;2018:237, Doctoral thesis, 2018)
      Currently, the development of offshore wind energy is mainly in shallow or intermediate water, where bottom-fixed substructures (e.g. monopiles and jackets) are mainly used. In harsh environmental conditions at certain ...
