In-Water Cathodic Protection (CP) Audits — Rotterdam

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 Rotterdam

Europe's largest port by cargo volume, with an extensive network of quay walls, sheet-pile berths, bridges, and subsea pipelines built up over more than a century of expansion.

The sheer scale and age of Rotterdam's submerged infrastructure — quay walls, bridge substructures, pipeline routes — makes ongoing 3D condition survey a genuine, standing requirement rather than a novelty.

Deliverable

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