Comparative study of circular and square gravity-based fish cages with different dimensions under pure current conditions
Mjåtveit, Magnus Aske; Cheng, Hui; Ong, Muk Chen; Lee, Jihoon (Peer reviewed; Journal article, 2021-12)Two typical gravity-based fish cages with circular and square shapes are modeled in the present study to compare their cage deformations, cultivation volumes and drag forces under different pure current conditions. Two hy ... -
Comparative study of five commonly used gravity type fish cages under pure current conditions
Cheng, Hui; Li, Lin; Ong, Muk Chen (Peer reviewed; Journal article, 2022-04)Gravity type fish cages have been commonly used in marine aquaculture for years. However, only limited research efforts have been made to assess the influences of different design parameters on the structural responses of ... -
Development of a coupling algorithm for fluid-structure interaction analysis of submerged aquaculture nets
Cheng, Hui; Ong, Muk Chen; Li, Lin; Chen, Hao (Peer reviewed; Journal article, 2021-12)A coupling algorithm between two open-source numerical toolboxes, i.e., OpenFOAM and Code_Aster, is implemented for fluid-structure interaction analysis of submerged nets. This algorithm is developed to handle the wake ... -
Development of Advanced Numerical Tools for Dynamic Analysis of Aquaculture Structures
Cheng, Hui (PhD thesis UiS;, Doctoral thesis, 2022-04)Numerical methods to accurately predict dynamic responses of marine aquaculture structures are essential in the engineering design process, because these structures can be subjected to large wave and current loads in the ... -
Dynamic response of a single point mooring submersible fish cages in waves and current
Wen, Xueliang; Cheng, Hui; Ong, Muk Chen (Peer reviewed; Journal article, 2023)Submersible fish cages are designed for installing in the open sea sites that are subjected to violent sea conditions to reduce the hydrodynamic forces acting on the fish cages. To assess the dynamic responses of a single ... -
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 (Peer reviewed; Journal article, 2021)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 ... -
Numerical study of two typical Norwegian gravity-based fish cages with different cage shapes and weights
Mjåtveit, Magnus Aske (Master thesis, 2021)Fish cages usually have net deformation in marine environments, and this deformation can reduce the cultivation volume of the fish cage and thus reduce the fish welfare. Hence, it is necessary to understand the structural ... -
Numerical study on structural responses of gravity-based fish cages
Sim, Jaesub (Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020)The location of a fish farm is moving towards more exposed locations due to spatial and environmental concerns. As the fish farm moves to open seas, the structure of the fish farm would undergo increased environmental loads ... -
Typical hydrodynamic models for aquaculture nets: A comparative study under pure current conditions
Cheng, Hui; Li, Lin; Aarsæther, Karl Gunnar; Ong, Muk Chen (Peer reviewed; Journal article, 2020-03)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 ...
