Withthegrid

Cathodic protection management software

For efficient and digital CP management

Withthegrid asset monitoring is an online platform for managing cathodic protection data. It is suitable for both service providers and asset owners. You can manage your CP data, connect remote monitoring sensors, analyze time series data and set up workflows.

Withthegrid cathodic protection remote monitoring solution

What’s the problem?

  1. Extending the life of steel pipes is only possible with proper CP protection
  2. Technical knowledge of CP is becoming increasingly scarce due to an aging workforce
  3. Managing CP data is becoming more complex through integration with IT systems and measurement data from remote monitoring sensors

Solution

The Withthegrid platform is designed to effectively manage cathodic protection data. It is a database, GIS system and workflow system combined into one. Not only does it store CP measurement data, it also displays it geographically while linking it to respective measurement locations. Your existing manual measurement reports can be designed, for locations which are not equipped with a CP sensor to be monitored from within the Withthegrid environment.

What are the advantages?

  1. Insight into the risks related to CP
  2. Reduced administrative burden
  3. Reduced workload for technical staff
  4. Lower inspection costs
  5. Faster damage detection
  6. Up-to-date insight into CP status and follow-up actions

Why the Withthegrid system?

  1. Simple and clear CP management software (with or without sensors)
  2. Sensors can be applied to all types of CP installations
  3. Fast integration with existing IT systems and work order systems

What is cathodic protection?

Cathodic protection is a way of protecting pipes from corrosion. This preventive measure supplies a direct current to steel pipes that run into soil or water. Due to the electric current on the steel pipes there is a potential drop.

What is telemetry?

Telemetry, or remote control, is the remote monitoring of conduits with the aid of sensors. Withthegrid sensors are connected to an asset and periodically send encrypted measurement data to an online dashboard. Our digital map shows which parts of the pipe are functioning properly and which ones need attention. In the event of a malfunction, you are immediately notified. The panel will then show what action needs to be taken. Once implemented, actions can be analyzed.

Why remote control?

The main advantage of remote control of cathodic protection is faster fault detection. This can be a rectifier turned off, disconnected test points following field work or unexpected excavation damages. Because disruptions can be resolved faster, the lifetime of the asset is extended. In responding to status changes,CP technicians can be deployed virtually with a digital dashboard, resulting in a significant savings in paid time. This also reduces the number of vehicles on the road, which results in lower CO2 emissions.

Measuring and monitoring cathodic protection with Withthegrid sensors:

Withthegrid sensors monitor cathodic protection on steel pipes. Our sensors are connected to the rectifier and various measuring points along the pipe. Both the voltage ( DC + AC ) and the current (DC + AC) are measured (in accordance with NEN-EN 13509: 2003 ) . A coupon measurement is also possible to measure the IR-Free (in accordance with ISO-NEN18086: 2015). The data is then sent to a digital dashboard. This allows transparency within the entire CP system. Additionally, the rectifier can be switched for the execution of off potential measurements or for doing work on the pipelines.

Which CP installations does the Withthegrid system work on?

Modbus connection rectifiers: For the Amstel rectifiers with a Modbus connection, a specific sensor is available (Amstel modbus sensor powered by Withthegrid) to ensure that settings in the rectifier can be adjusted remotely and that precise and synchronous switching can be made. 

Other rectifiers: Other rectifiers are read out and switched via an analog connection. Accurate and synchronous switching is made possible thanks to an external Eaton relay.

CP – points: The Withthegrid sensors can be placed in metal poles and round plastic poles.

AC / DC-drains: The Withthegrid sensors may also be placed in drains.
