    • Effects of mooring line breakage on dynamic responses of grid moored fish farms under pure current conditions 

      Cheng, Hui; Li, Lin; Ong, Muk Chen; Aarsæther, Karl Gunnar; Sim, Jaesub (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-17)
      Due to the lack of sheltered area, Norwegian fish farms are expanding to more exposed and remote sites. The severe environmental conditions in exposed sites can increase the risk of structural failure during aquaculture operations. In the present study, the program FhSim is employed to conduct time-domain simulations to investigate structural responses of a single-cage and 1 × 4 multi-cage fish farm ...

    • Numerical investigation on the cage-to-cage wake effect: A case study of a 4 × 2 cage array 

      Sim, Jaesub; Cheng, Hui; Aarsæther, Karl Gunnar; Li, Lin; Ong, Muk Chen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-12)
      Aquaculture has been the world’s fastest-growing food producing method and grown to become the second-largest export industry in Norway during the past 40 years. Usually, the high-value fish such as Atlantic Salmon (<i>Salmo salar</i>) is raised in a multi-cage fish farm, where the flow interactions between fish cages exist. In this study, the interactions between fish cages are implemented into the ...

    • Typical hydrodynamic models for aquaculture nets: A comparative study under pure current conditions 

      Cheng, Hui; Li, Lin; Aarsæther, Karl Gunnar; Ong, Muk Chen (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-17)
      The net is regarded as the most critical component in marine aquaculture facilities as it is the only barrier which protects the environment from fish escapes. Accurate predictions of the net cage deformation and drag force on the nets are needed, both for ensuring fish welfare and for dimensioning of the mooring system. Thus, an appropriate hydrodynamic model is essential. In practice, two types ...
