Finite Element Analysis of the Effect of Currents on the Dynamics of a Moored Flexible Cylindrical Net Cage

A numerical model associated with wave–current interactions a moored flexible cylindrical cage was developed based on the finite element method. An analytical formulated under linearised wave theory and small structural response, semi-analytical solution obtained using Fourier Bessel series least squares approximation method, along matching technique. The results from analysis of horizontal displacements for different design parameters uniform current were compared solutions. It seen that they had good level agreement their results. effects speeds time shapes analysed Further, mooring forces values height radius also presented. comparison indicated could be used confidence in net applications to offshore aquacultures.
