Extensive Underwater Bridge Inspection

Planys one of the best underwater bridge inspection companies conducted underwater visual inspection at two railway bridges that are over 85+ years old in West India. The underwater bridge inspection was 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’ remote operated vehicle Mikros, equipped with high resolution camera, altimeter and depth sensor.

  1. Over 45 anomalies were identified during the bridge inspection and were categorised into minor, moderate & major based on the size of the defects that included cracks, honeycombing and cavities.
  2. Planys’ proprietary image enhancement algorithm was used to enhance the videos taken in the extremely turbid waters
  3. 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.
  4. The client could take relevant action for repairs and maintenance based on Planys’ findings.
