Cathodic protection remote monitoring is the continuous, automated measurement of CP system performance, with data transmitted from field equipment to a central platform for analysis, reporting and alarm management. Remote monitoring replaces the traditional reliance on periodic manual site visits with always-on visibility of pipe-to-soil potentials, transformer rectifier output and protection status. Corrpro Europe supplies and integrates remote monitoring systems for onshore and marine ICCP installations, with full compatibility with our Hockway™ transformer rectifier range.
Most cathodic protection systems are still inspected manually at intervals set by ISO 15589-1 or AMPP SP0169. Between visits, there is no continuous data on whether the system is delivering protection. Three operational problems follow from this:
Remote monitoring addresses all three by collecting data continuously, transmitting it automatically and presenting it through a central platform that operators can access on demand.
A typical CP remote monitoring installation consists of:
Reference electrodes (copper/copper sulphate, silver/silver chloride, zinc) measure pipe-to-soil or structure-to-electrolyte potential at representative locations. Test stations capture multiple measurement points along a pipeline route.
Field-installed loggers record measurement values at programmed intervals, between 1 second to 1 hour. Loggers are typically powered by mains supply (where available), solar with battery backup or long-life battery, depending on location.
Output voltage, output current, AC input status and alarm conditions are recorded directly from the Hockway™ TR or an equivalent unit. The Hockway™ Remote Monitoring and Control System (RMCS) allows two-way communication, including remote setpoint adjustment.
Data is transmitted is typically through fibre cable but we can also offer models via cellular (4G/5G), satellite (for remote routes), depending on site infrastructure and operator requirements.
A remote dashboard provides real-time visualisation, historical trend data, alarm management and report generation. Compliance reports against ISO 15589-1 acceptance criteria are produced automatically.
Corrpro Europe remote monitoring and control systems provide:
The system architecture is designed for scalability, from a single tank farm to a multi-asset pipeline network spanning multiple countries.
Cathodic protection remote monitoring and control is specified across:
Remote monitoring is particularly valuable where assets are remote, where AC interference risk is elevated (HVAC overhead line crossings, solar farm proximity), or where regulatory inspection requirements demand a continuous data trail.
Corrpro Europe remote monitoring installations support compliance with:
Automated reporting against ISO 15589-1 inspection requirements removes the manual data compilation effort and provides a defensible audit trail for integrity reviews.
Operators that adopt CP remote monitoring typically report:
For operators managing distributed pipeline networks or large tank farms, the operational case for remote monitoring is typically established within the first year of operation.
Cathodic protection remote monitoring is the continuous, automated measurement and control of CP performance, with data transmitted from field equipment to a central platform. It captures pipe-to-soil potential, transformer rectifier output and alarm status without requiring a site visit.
ISO 15589-1 sets out minimum monitoring intervals depending on the asset class and protection method. For most onshore pipelines, annual surveys and more frequent test point measurements are required. Remote monitoring does not replace the need for periodic detailed surveys, but it provides continuous data between surveys and supports compliant reporting.
Yes. Most modern transformer rectifiers, including older Hockway™ units, can be retrofitted with the Remote Monitoring and Control System (RMCS) or a comparable third-party module. Standalone data loggers can also be added to monitor reference electrode potential without modifying the TR.
Standard data points include pipe-to-soil potential (on and off measurements), transformer rectifier output voltage and current, AC input status, AC interference voltage (where applicable) and alarm conditions. Capture intervals are typically configurable between 1 minute and 24 hours. We can also monitor AC / DC current density and corrosion rates using ER probes.
Yes. Marine ICCP systems on FPSOs and other offshore structures can be monitored remotely using the same architecture as onshore installations, with fibre optic cable and through the internet. The Hockway™ RMCS is widely deployed on marine ICCP installations.
To discuss adding remote monitoring to an existing cathodic protection system or specifying remote monitoring as part of a new ICCP installation, contact the Corrpro Europe engineering team. Our specialists are AMPP and ICorr certified and have integrated remote monitoring across pipelines, tank farms, offshore platforms and marine vessels.
Existing Hockway™ transformer rectifiers can be retrofitted with the RMCS in most cases. New installations are supplied with monitoring as a fully integrated option.
