Vibration and noise reduction in ships and floating structures can significantly enhance dynamic stability and improve hydrodynamic performance during navigation, exploration and exploitation of deep and ultra-deep offshore geo-resources. In this paper, slip damping with sandwich composite elastic beam-plate smart structures for dissipation of vibration and active noise control mechanism is investigated analytically. For this problem, a boundary value partial differential equation is formulated for linear and non-linear hydrodynamic wave loading. In particular the effect of interfacial pressure distribution variation at the interface of the layered smart structures on the energy dissipation, logarithmic damping decrement and spatial transfer function is analyzed and presented for design application and selection of stabilizers.
