Wall Thickness Measurement

Detect material loss before it becomes a risk.

Subsea structures are continuously exposed to corrosion, erosion, and fatigue. Wall thickness measurement provides a quantified picture of material loss at any point on your asset, enabling accurate fitness-for-service assessments.

Corrosion Mapping

Know exactly where degradation is happening.

Corrosion mapping generates a full-surface picture of metal loss across your structure. By scanning large areas systematically, we produce a spatial dataset that shows degradation patterns, severity zones, and progression rates.

Weld Inspection

Spot and size flaws in critical joints.

Welds are the most failure-prone features on subsea structures. We offer both full raster scanning and targeted spot-checking depending on the inspection class required. Our systems detect, locate, and size cracks, lack of fusion, and porosity with high precision.

CP

Cathodic Protection Survey

Validate your corrosion protection system.

Cathodic protection is the primary defence against electrochemical corrosion on subsea steel. Our survey measures protection potential across the structure, identifies depleted or failed anodes, and maps risk zones for prioritised maintenance planning.

Visual Condition Survey

A complete picture of your asset's condition.

Visual surveys provide the baseline condition record required before any detailed inspection campaign. From general overview surveys to close-up examination with marine growth removal, our systems capture high-definition video and images georeferenced to your asset structure.
