THE MOTION OF BUOYANT SYSTEMS IN RESPONSE TO UNDERWATER SHOCK LOADING

Pressure, impulse, velocity and displacement parameters associated with the shock wave from an underwater explosion are identified. Consideration is given to the shock wave interaction at the fluid/structure interface in order to estimate velocities and displacements for both free plates and buoyant bodies, and to relate the change in momentum of the body to the impulse of the shock wave. The simplified approaches adopted allow bounds on velocities and displacements to be established which may be used as input for design, testing and computational studies. The shock parameters are linked to damage potential for surfaced and submerged buoyant platforms. Associated bubble interactions are briefly considered.
