The disclosed embodiments include in-line inspection devices, methods to perform in-line inspections of pipeline and protective casings, and methods to determine anomalies of pipeline and protective casings. The method includes deploying an in-line inspection device in a section of a pipeline enclosed by a protective casing. While the in-line inspection device is traveling along the pipeline, the method also includes transmitting, at a frequency, a transmitted signal toward the protective casing; and detecting a scattered signal scattered by the protective casing. The method further includes detecting a scattered signal scattered by the protective casing. The method further includes locating an anomaly of the protective casing based on the scattered signal.

In-line inspection devices

Dynamic pressure wave propagation can be used in pipelines to provide information about the available, unobstructed diameter and any partial or complete blockages in the pipeline. Based on this information, a system can automatically determine optimal times to launch pipeline inspection gauges for cleaning or other purposes. A pipeline inspection gauge is sometimes referred to as a pig. Certain aspects and features include a system that can launch pigs as needed automatically by activating an automatic multiple pig launcher at appropriate times.
