Pipeline Following Sensor Arrangement

A method and apparatus for installing a monitoring cable or other utility near an existing pipeline. An electromagnetic signal may be induced on the pipeline, either directly, or by transmitting a signal from a vehicle carrying a sensor array. The sensors disposed on the vehicle communicate with a processor to determine a distance and orientation of the vehicle relative to the pipeline. The signal may be electromagnetic, acoustic, capacitive, or the like. A plow or other digging tool may be on the vehicle or a secondary vehicle. Such a digging tool opens a trench and installs the cable along a path disposed next to the pipeline within an acceptable distance range from the pipeline. The vehicle may be remotely or automatically operated.
