Abstract: A marine acoustic source system has relativley densely packed energy sources arrayed in a tandem-like fashion along a horizontal plane. Preferably, a longitudinal axis of each source lies orthogonal to a pre-determined towing direction. The system includes protective tubes that encloses supply lines and auxiliary equipment, and a harness. The harness provides the primary mechanical connection for towing the sources through the water. To minimize bending of the supply lines, connectors having angular portions connect the sources to the supply lines. Further, the sources can be arranged such that source connection interfaces for receiving power, hydraulic fluid, or data point alternately in opposing directions. During use, the sources, e.g., air guns, are supported at a predetermined depth beneath the water's surface by a floatation buoy. Upon activation, the sources of a cluster each release individual air bubbles into the water. Because the air guns are relatively densely packed, the individual air bubbles coalesce into a single bubble that produces the desired acoustical signal.

Abstract: An in-water distributed control system for use in marine seismic survey. The system includes a shipboard interface and power supply coupled to an in-water subsystem via a high bandwidth communication link. The in-water subsystem includes a remote control module for generating firing commands based on synchronizing and position parameters transmitted by the interface. The remote control module transmits power, data, and commands to a plurality of gun control modules. Each gun control module operates an air gun. An individually addressable remote cut-off valve controls air to each air gun. Depth and pressure at the gun control module is sensed by at least one DT/PT module. An optional expansion unit provides additional DT/PT capability.

Abstract: A graphical user interface (GUI) and control system for marine seismic data acquisition is described along with a method of real-time quality control of the seismic survey. The control system includes real-time data processing of individual source near-field measured signals and concurrent synthesis of array far-field signatures. The control system determines individual source out-of-specification conditions and computes far-field signatures based on an array configuration excluding the failed source. Source, array, and troubleshooting information are presented to a user in real-time over a GUI monitor to allow informed decision-making regarding continued and/or modified survey operations and operational parameters.
