• Analysis of full-scale riser responses in field conditions based on Gaussian mixture model 

      Wu, Jie; Eidnes, Sølve; Jin, Jingzhe; Lie, Halvor; Yin, Decao; Passano, Elizabeth Anne; Sævik, Svein; Riemer-Sørensen, Signe (Peer reviewed; Journal article, 2022)
      Offshore slender marine structures experience complex and combined load conditions from waves, current and vessel motions that may result in both wave frequency and vortex shedding response patterns. Field measurements ...
    • Experimental study of current forces and deformations on a half ellipsoidal closed flexible fish cage 

      Strand, Ida Marlen; Sørensen, Asgeir Johan; Volent, Zsolt; Lader, Pål (Journal article; Peer reviewed, 2016-08)
      Closed flexible fish cages are proposed as a new concept in marine aquaculture, replacing the conventional net cages in order to meet ecological challenges related to fish lice and escapes. It is important to understand ...
    • Hydroelastic response of concrete shells during impact on calm water 

      Abrahamsen, Bjørn Christian; Grytten, Frode; Hellan, Øyvind; Søreide, Tore H.; Faltinsen, Odd Magnus (Peer reviewed; Journal article, 2023)
      Many ocean structures located offshore are supported by large vertical concrete columns. High and steep storm waves – in the process of breaking – may induce large local slamming loads on these columns. The present work ...
    • Numerical and experimental investigations on mooring loads of a marine fish farm in waves and current 

      Shen, Yugao; Greco, Marilena; Faltinsen, Odd Magnus; Nygaard, Ivar (Journal article; Peer reviewed, 2018-05)
      A realistic aquaculture fish farm system in both regular and irregular waves is investigated by numerical simulations and model tests. The main purpose is to develop a reliable numerical tool and in this respect to investigate ...
    • Numerical and experimental study on the drainage and collapse of a floating flexible bag structure 

      Kristiansen, David; Su, Biao; Volent, Zsolt (Journal article; Peer reviewed, 2018-11)
      This paper addresses the possible drainage and collapse of closed flexible cages in sea-based fish farming. A closed flexible cage is a floating bag structure containing water that is enclosed from the ambient water. ...
    • Sloshing in a rotating liquid inside a closed sea cage for fish farming 

      Tsarau, Andrei; Lugni, Claudio; Lucarelli, Alessia; Kristiansen, David; Lader, Pål Furset (Peer reviewed; Journal article, 2021)
      Sloshing in a sea cage with a slowly rotating liquid is investigated. The cage is axisymmetric, and the liquid is subjected to a nearly uniform angular velocity about the vertical axis of the cage. Both experimental and ...
    • The influence of fish on the mooring loads of a floating net cage 

      He, Zhao; Faltinsen, Odd Magnus; Fredheim, Arne; Kristiansen, Trygve (Journal article; Peer reviewed, 2018)
      The influence of fish on the mooring loads of a floating net cage is studied numerically and experimentally. Two experimental series were conducted. One case was model tests with artificial fish. Nine rigid fish models ...
