This episode presents a novel finite-element model for analyzing the hydroelastic behavior of large, floating visco-elastic membranes. The model couples a 2D membrane equation with a 3D potential-flow equation in the frequency domain, capturing both elastic deformation and viscous structural dissipation. The study explores the application of these membranes in offshore engineering, particularly as floating breakwaters and wave energy converters. It includes convergence analysis, modal analysis, and frequency domain solutions for 1D and 2D membrane configurations, examining the influence of material properties and wave conditions. The research investigates the energy absorption capabilities of the membrane and its potential for wave energy extraction. Finally, the model is applied to simulate a floating membrane around a monopile foundation, showcasing its capacity to handle complex geometries and providing insights into wave-structure interactions.
