Sonomatic Australia completed an underwater corrosion mapping campaign on a series of marine steel bridge piles to assess structural condition and identify areas of wall loss.
Subsea Corrosion Mapping of Marine Bridge Piles Case Study
Introduction
The inspection covered multiple pile locations using automated ultrasonic corrosion mapping technology.
Challenges
-
Marine growth and tidal conditions limited access to some inspection areas.
-
Comprehensive data was required across the full circumference of each pile in a subsea environment.
-
Accurate quantification of corrosion was needed to support future integrity planning.
Solution
Automated ultrasonic corrosion mapping was deployed to collect high-resolution wall thickness data and generate detailed 2D and 3D corrosion maps of the inspected areas.
Outcomes
-
Corrosion-related wall loss was identified and quantified across all inspected locations.
-
Detailed condition data provided a clear understanding of pile integrity
-
Inspection results supported informed maintenance and asset management decisions.
-
Advanced NDT technology delivered efficient, high-resolution assessment of critical marine infrastructure
