A 3D mathematical model associated with wave interaction with a horizontal floating flexible membrane supported by linear springs under linearized small-amplitude wave theory is presented. The dispersion relation of the referred problem is derived based on Green’s function technique and it is utilized in the solution by employing the velocity decomposition method. The level of accuracy of the analytical results is checked by comparing the results of reflection and the transmission coefficients against experimental model tests for different spring stiffnesses. The experimental setup, moadel preparation, and wave characteristics in the experimental program are described and the results of the model tests are presented. Further, to investigate the effect of linear springs and associated design parameters, several comparisons between the experimental results and analytical solutions are presented. The analysis covers spring and fixed edge connections from experimental model tests, 3D membrane deflection as well as wave loads on the membrane for different spring stiffnesses, membrane tension, water depths, modes of oscillation, and membrane width. The initial results analysis will allow a better understanding of the membrane response to develop a flexible membrane wave energy converter.
