In-Water Cathodic Protection (CP) Audits
Electrical voltage potential measurement on steel piers using a CP probe, with anode health readings linked directly to the 3D infrastructure map.
What This Involves
A cathodic protection system on a steel pier or piling only works if the anodes are actually protecting the structure — which requires an in-water voltage potential survey to confirm, not an assumption based on anode age. We run a CP probe survey across the structure and link every reading directly to its location on the 3D infrastructure model, so an operator can see which sections are adequately protected and which anodes need replacement at a glance, not buried in a table.
How It's Done
CP probe survey across the structure at an agreed measurement grid
Voltage potential readings logged against precise location
Readings linked to the 3D structure model, flagging areas outside protection criteria
Anode replacement priorities identified from the resulting map
Deliverable
A CP survey report with voltage readings mapped onto the 3D structure model, flagging under-protected areas.
Who It's For
Port authorities and asset owners with a scheduled cathodic protection monitoring requirement.
