Self Excited Eddy Currents (SEEC) present a unique and novel method for internal inspection of natural gas transmission pipelines for the presence of features aligned with the main pipe axis such as Stress Corrosion Cracking (SCC). This paper outlines the theory, methodology and basic design principles of building a SEEC based tool. Results from initial proof of concept testing are presented.
