 gate transistor during read operations. Also, the architecture for programming the array is not shown in detail but appears to require a relatively large number of lines to program and read the array and have considerable power consumption and space requirements. Since the marine seismic industry has progressed to towing multi-equipment, including two or more streamers, from one vessel, there has been a substantial increase in the operational down time whenever it is necessary to make repairs to a single streamer. Retrieving only a single streamer from among a plurality of towed equipment requires that the vessel maintain a nominal forward motion throughout. Utilizing present methods and apparatus, reeling in a single streamer while the vessel maintains a nominal forward motion results too frequently in damage to the streamer, i.e., holes, pinched wires and crushed bulkheads. Thus, the present industry norm dictates that the vessel be backed up while retrieving a streamer. This requires that all towed equipment be picked up, substantially increasing the effort and operational down time.
Streamers are complex cables usually comprised of a fluid filled jacket having a diameter of three or more inches. Some of the newer cables utilizing fiber optics may have diameters closer to two inches. There are various and numerous types and builders of seismic cables with associated varieties of includable equipment and means for their attachment. Generalizing with respect to this variety, cables are typically comprised of multiple electric lines, steel stress members, bulkheads, interconnects, hydrophones, program plugs, bird collars, and other equipment, predominantly encased in a polyurathene or PVC jacket. The typical jacket wall thickness is about 1/8 of an inch
Streamer lengths typically run between 2000 to 5000 yards. Each length is comprised of multiple sections. A section may run approximately 50 yards. Sections are connected by rigid connectors, several inches in length. Some connectors may exceed a foot in length. The connectors are held to the jacket by attachment means such as punch lock bands. Sections frequently contain, coupled within their length, other equipment, such as program plugs or bird collars. The plugs are comprised of rigid cylinders approximately twelve to fifteen inches long and are fixed within the jacket by attachment means such as punch lock bands. Bird collars are usually screwed around the circumference of the jacket, intermediate the sections.
A seismic cable must be handled with care. The length of the housing for certain of the included equipment dictates that the cable not be wound upon a drum with a curvature too great to accommodate certain straight cylindrical portions. The punch
