What is cathodic protection remote monitoring?

Remote monitors use technology to collect and monitor CP system data for pipelines, tanks, and other assets. Operators use this data to comply with regulations and identify and address potential CP system problems before damage or corrosion occurs.

How does remote monitoring work?

Cathodic Protection Remote monitors are installed at system rectifiers, test stations, and more. Equipped with sensors to collect data such as voltage, current, and temperature, they deliver data via cellular or satellite networks to integrated software such as Bullhorn Web. This enables technicians to easily analyze their CP system data anytime, anywhere. In addition, RMUs enable CP system interruption for close interval surveys, test station polling, and troubleshooting.

The best cathodic protection RMUs also protect cathodic protection system assets from damaging electrical surges.

Benefits of cathodic protection remote monitoring

There are several significant economic and environmental benefits to using CP RMUs.

  • Reduced costs—CP remote monitoring greatly reduces the costs associated with CP system maintenance and inspection. Once done by personnel often traveling to remote locations, CP RMUs monitor data 24/7, enabling operators to quickly identify and address issues and avoid costly repairs and downtime.
  • Improved safety—Remote monitoring improves safety by greatly reducing the need for personnel to travel to remote locations to collect CP data. This is especially beneficial in hazardous environments.
  • Improved performance and asset life—Real-time data simplifies cathodic protection system maintenance, ensures greater uptime, and extends the life of assets.
  • Increased efficiency—CP remote monitoring increases the efficiency of CP programs by automating the data collection and analysis process. This allows CP technicians to focus on more important tasks.
