The environment and structure of the tanks used in aquaculture vessels are remarkably different from those of ordinary ships,and the resulting problem of structural strength is related to breeding safety.In this study,a model of aquaculture tank corrosion was constructed by using the multiphysical field coupling analysis software COMSOL Multiphysics,and wave and sloshing loads were calculated on the basis of potential flow theory and computational fluid dynamics.The influence of different calculation methods for corrosion allowance and sloshing load on the structural responses of aquaculture tanks was analyzed.Through our calculations,we found that the corrosion of aquaculture tanks is different from that of ordinary ships.The corrosion allowance in Rules for the Classification of Sea-going Steel Ships is small,and the influence of the aquaculture environment on corrosion can be ignored.Compared with the method set in the relevant rules,our proposed coupling direct calculation method for the structural response calculation of aquaculture tanks can better combine the specific environment of aquaculture tanks and provide more accurate calculations.
