On-board noise and vibration has become an important concern across the maritime industry. Prolonged exposure to noise and vibration causes an unsafe working conditions and reduces the performance of marine professionals. In order to mitigate noise and vibration generated by on-board sources, a proper design of the insulation system and ship structural dynamics should be carried out. Viscoelastic materials (VEM) are widely applied as damping materials for structure-borne noise and vibration control in various industries. The most notable examples are aerospace, automotive and marine industries. But still now there is no standard design formulation to apply VEM effectively to the ship’s hull structure. This study provides a better understanding on the effects of VEM on ship structures in order to provide ship designers with effective ways to simulate the dynamics of VEM when applied to ship structures.
