| description | The goal of this paper is to provide a comparative analysis of two commonly used approaches to discretize offshore fish cages： the lumped-mass approach and the finite element technique. Two case studies are chosen to compare predictions of the LMA（lumped-mass approach） and FEA（finite element analysis） based numerical modeling techniques. In both case studies, we consider several loading conditions consisting of different uniform currents and monochromatic waves. We investigate motion of the cage, its deformation, and the resultant tension in the mooring lines. Both model predictions are sufficient close to the experimental data, but for the first experiment, the DUT-Flex Sim predictions are slightly more accurate than the ones provided by Aqua-FETM. According to the comparisons, both models can be successfully utilized to the design and analysis of the offshore fish cages provided that an appropriate safety factor is chosen. |
