ABSTRACT:
A plurality of submerged control station junction boxes each include a microprocessor having data storage and transmission capability, airgun firing and related electronic circuits to control a predetermined airgun or airgun groups. These junction boxes are towed at spaced positions along an airgun array. An electrical cable and sections of high pressure air supply line are detachably coupled to each junction box. The predetermined airguns to be controlled by a junction box are detachably coupled thereto. Thus, the number of airguns in the towed array can be changed by coupling or uncoupling junction boxes and the associated airguns controlled by them. The junction boxes are automatically cooled on shipboard by increasing low pressure air until a relief valve opens for establishing a continuous cooling flow of low pressure through a protective hose sheath and the junction boxes. Local electronic microprocessor units in the respective junction boxes serve as local control and communication stations, and they communicate through a bus line with a master control station on shipboard. The junction boxes include electrical capacitors charged during intervals between firings of the airguns. These capacitors are controllably discharged in response to command signals from the master station for firing the airguns. The junction boxes and a protective hose sheath containing the electrical power supply lines and containing communication bus lines to the respective junction boxes are pressurized with low pressure air during submerged towing for excluding water in the event of a leak.
