Cathodic Protection (CP) System Descriptions Features

Cathodic Protection (CP) systems are an important method for preventing corrosion in buried pipelines and an essential part of the Integrity System.

All operators must perform periodic measurements of the CP level reached. This requires periodic measurements at rectifiers and at specific test points along the entire line. The application of remote CP monitoring and supervision technologies in pipelines has proven to be a reliable and cost-effective means of monitoring the proper functioning of cathodic protection systems.

Experience and Career

GIE Group has extensive experience in the supply, assembly, commissioning, and start-up of remote monitoring systems for Watchdog II cathodic protection rectifier units from the manufacturer Elecsys.

These systems allow monitoring of one or more rectifiers in plants or tank farms, well pipes and casing, docks, among others.

They have a powerful web interface and mobile app that simplify the scheduling of GPS-synchronized outage cycles for multiple rectifiers, group on/off potential surveys, and automatic generation of compliance reports.

The Monitoring System

The "Mesh" wireless sensor modules are physically and electrically isolated from the base station, virtually eliminating lightning damage to the remote monitoring system.

The fail-safe GPS synchronized current switch features a robust 100 A mercury relay. It incorporates a high-impedance voltmeter that allows instantaneous off-potential readings with a programmable delay (250 ms to 60 seconds).
