Abstract
Computing device, software and method for balancing forces acting on a piston of a marine vibrator towed in a body of water. The method includes estimating with a management system located on a vessel or a controller located on a marine vibrator, a transient pressure disturbance in the body of water; computing, at the controller, a force correction for the piston of the marine vibrator, based on the transient pressure disturbance; and instructing an actuation system of the marine vibrator to apply the force correction to the piston in anticipation of an arrival of the transient pressure disturbance.
