Planys conducted underwater visual inspection at two railway bridges that are over 85+ years old in West India. The inspection aimed to identify damages and deformations that could affect the structural integrity of the bridge piers
Scope of Work: Underwater visual inspection of submerged parts of 4 specific piers.
Planys Solution: The inspection was performed using Planys’ ROV Mikros equipped with high resolution camera, altimeter and depth sensor.
- Over 45 anomalies were identified and categorised into minor, moderate & major based on the size of the defects that included cracks, honeycombing and cavities.
- Planys’ proprietary image enhancement algorithm was used to enhance the videos taken in the extremely turbid waters
- All anomalies/defects were plotted against geo-tagged CAD drawing of every section on the Planys Analytics Dashboard (PAD) with localised click-to-view video.
- The client could take relevant action for repairs and maintenance based on Planys’ findings.
