Traditional sacrificial anodes are buried in the ground to protect steel structures such as steel tanks and pipelines. They generally require excavation and replacement every ten years as the sacrificial anodes become depleted. Many of these systems are installed under congested urban locations and replacement causes huge disruption and significant costs over the lifetime of a pipeline.

The initial systems themselves can be relatively inexpensive with a typical ten-year life magnesium anode bed costing around $3500 to supply, install and commission. The cost of excavating and replacing the same bed can be up to $10000 per site per ten years, not to mention the disruption caused to traffic flows and inconvenience for the urban population.

Considering anode beds are located every two to three kilometres along a pipeline when considering a 50-year service life, the ongoing costs can run into several hundreds of thousands of dollars.

The GreenAmp Sacrificial Anode Replacement (SAR) is a Mini Impressed Current Cathodic Protection (ICCP) unit that provides a cost-effective alternative to sacrificial anodes.

Data generated such as volts, amps, pipe potential and even synchronised instant off readings are an available option from our cloud based portal with the addition of our GreenAmp remote monitoring unit, all that is required is either internet access via a Wi Fi connection or cellular LTE M (Cat M1) or NB IoT coverage. Remote monitoring will attract an annual subscription fee which covers the data transmission and access to our secure portal which features configurable alarm states, alarm emails, polarisation graphs, active map, device lists and configuration settings.
