Pressure compensation for a marine vibrator

Abstract

A marine vibrator assembly includes a vibrational source; a hose connectable between the vibrational source and a gas source; and a releasable coupling between the hose and the vibrational source. A method of operating a marine vibrator assembly includes deploying a vibrational source into a body of water at a first depth, wherein an internal pressure of the vibrational source balances an external pressure on the vibrational source at the first depth; supplying gas at a flow rate to an interior of the vibrational source from a gas source as the vibrational source moves from the first depth to a second depth, wherein the internal pressure of the vibrational source balances the external pressure on the vibrational source at the second depth; stopping the supplying the gas from the gas source.
