A survey of over 5,000 Km of pipelines was developed in 2006 to assess the CP performance of the pipelines located in the main ROWs of the Mexican States of Veracruz, Tamaulipas, Nuevo Leon, Coahuila, Durango, y Chihuahua. Historically the CP surveying in the region has been done measuring the ON potentials and applying the –850 mV criterion to these measurements. By employing a set of several satellite synchronized by GPS instrumentation, the instant OFF potentials presently reported resulted considerably more electropositive, and the compliance to the -850 mV criterion was found under 50%, in a set of over 5,000 measurements in this important region of Mexico. Besides the needs of new CP infrastructure, we report the main causes that impair the compliance of the CP to the -850 mV criterion of the NACE RP 0169 – 2002.
