Abstract:Float collar is an important component for the fish cage systems which are applied by the aquaculture industry. The integrity and reliability of the float collar are detrimental in order to avoid the critical failure which may lead to major loss and severe consequences. A finite element model for the structural analysis of the float collar for the metal fish cage in waves is developed and validated by comparing with the experimental data. The numerical simulation is performed to conduct the parametrical study of float collar and to analyze the deformation and the stress of a metal fish cage in waves. The results indicate that the numerical model can accurately predict the deformation of float collar and the tension force on mooring line. When the central angle of the arc between two neighboring clamps is larger than 15 degrees, the influence of the amount of clamps on the deformation of float collar is decreased significantly. For the metal fish cage structure, the upper part of the nets for the metal fish cage experiences the largest deformation, and thus the diameter of the net twine at the upper part of the metal fish cage should be increased to avoid the structural failure.
