METHOD AND SYSTEM FOR HYDROSTATIC BALANCE CONTROL, BASED ON PRESSURE MODELLING, OF A MARINE SEISMIC VIBRATOR

摘要

Computing device, software and method for balancing forces acting on a piston of a marine vibrator (300) towed in a body of water. The method includes estimating (800) with a management system (403) located on a vessel (402) or a controller (330) located on a marine vibrator (300), a transient pressure disturbance in the body of water; computing (802), at the controller (330), a force correction for the piston of the marine vibrator, based on the transient pressure disturbance; and instructing (804) an actuation system (318) of the marine vibrator (300) to apply the force correction to the piston in anticipation of an arrival of the transient pressure disturbance.
