Abstract
Systems, methods and program products of instructions stored on a computer readable medium related to a tether free piggable inspection tool capable of detecting holidays and able to read and store non-conductive internal coating thickness values in very long conductive pipes, along with distance values for further off-line analysis, are provided. The inspection tool includes a plurality of thickness probes, a data storage unit, a control unit, a plurality of navigation wheels and a holiday detector that uses an electrical conductive medium, such as a gas or fluid, as the ground connection. A closed loop configuration is adopted allowing the system to autocorrect itself for different coating thicknesses along the pipe.
