Single Cable sonar/video systems from Cobra Technologies are designed for large-diameter pipeline inspections using a single cable up to 6,000 feet in length. Systems can be mounted on floats or large crawler-based platforms for use in 12-inch to 200-inch diameter pipes. The sonar sediment report provides a graph, indicating the volume of sediment, highest level of sediment and the percentage of sediment blockage for all pipeline segments observed (captured) during inspection. 800/443-3761; www.cobratec.com.
