In-Water Cathodic Protection (CP) Audits — Valletta

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 Valletta

The Grand Harbour is one of the Mediterranean's established ship repair centres, and Malta's waters hold one of the region's best-documented concentrations of WWII-era wrecks, supporting a genuine wreck-diving and heritage tourism industry.

An active repair yard economy alongside a well-known wreck-heritage sector makes Malta a genuine fit for both class-driven hull survey work and non-invasive historical wreck documentation.

Deliverable

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