Dynamic simulation of the fish cage net and floating collar subjected to currents and waves

The fish cage system consists of netting, mooring ropes, a floating collar, floats, sinkers and anchors. Whole elements of the cage system were modeled on the mass-spring model. The modeling method was applied to the dynamic simulation of the actual fish cage system simultaneously influenced by the current and waves in order to evaluate their practicality. Computer-based simulation provides a method to quantitatively analyze the environmental forces acting on fish cage systems and thereby provides valuable information necessary for designing an optimal structure.
