“…Using the Fourier-Bessel series expansion formula, the velocity potentials satisfying governing Equation (8), along with the relevant boundary conditions in Equations ( 8)-( 10), (15), and (20) in their respective regions, the velocity potentials in R 1 , R 2 , and R 3 are derived as…”

“…To obtain the added mass and drag coefficients in the Morison Equation, forced oscillation tests were conducted to simulate the water particle motions around a hollow cylinder in waves and the results were applied in their FEA model in [14]. In order to apply the buoyant load correctly, a "Buoyancy Distribution" method was developed using parallel beam elements to model the collar [15]. The comparison of different models of the net with the experimental results was made in [16] and concluded that these models can calculate the hydrodynamic load under currents slower than 0.5 m/s accurately but overestimate the drag forces under large currents.…”

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

“…Therefore, if the floating collar is partly immersed, the buoyancy force cannot be calculated correctly. The "buoyancy distribution" method [19] was adopted in this study to deal with this instantaneous-buoyancy problem by replacing the partly immersed floating collar by several distributed coupled beams, as shown in Fig. 4.…”

“…He and Zhao (2012) introduced Sanders' mid-long cylindrical shell theory and its application to ocean engineering structures. Li et al (2013) studied the dynamic responses of the semi-immerged floater and the fish cage system consisting of the floater and nets in waves and currents with the help of ABAQUS software. Nevertheless, the research on the deformations of the elastic floating collars of net cages in waves is inadequate.…”
