In-Water Cathodic Protection (CP) Audits — Geneva

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.

Why it matters in Geneva

Sits at the point where Lake Geneva drains into the Rhône, a stretch of river developed with hydroelectric dams including the Seujet, Verbois, and Chancy-Pougny installations.

Hydro infrastructure on this stretch of the Rhône needs intake, spillway, and trash-rack inspection in flow conditions that are genuinely hazardous for divers — exactly the case for remote 3D survey.

Deliverable

A CP survey report with voltage readings mapped onto the 3D structure model, flagging under-protected areas.
