... ]. (This standard compares to NACE SP 0169). Remote controlled T/R’s operating in off-potential mode were implemented in the gas grid system throughout 2006. After the installation of remote controlled T/R’s all necessary data are online and can be used for detailed surveillance of the pipeline system. The data...

... that the coupon methodology could best be evaluated on structures which could be well characterized and for which the pipe off-potential could be accurately measured. This required a relatively isolated, single pipeline which lends itself to the interruption of all of the applied CP current and has...

...Abstract There are several factors that can introduce an error to the off-potential such that it no longer represents an accurate measure of the polarized potential at the steel surface. One such phenomena created between two areas of pipe due to a potential gradient on the pipe. Although long...

The overall objective of this project was to improve the ability to interpret close-interval on- and off-potential surveys in rights-of-way containing multiple pipelines...
