Underwater Dam Inspection by Coratia Technologies

Underwater robotics service

Underwater Dam Inspection

Underwater dam inspection uses ROV cameras, sonar, positioning, and measurement tools to document submerged gates, intakes, spillways, concrete, steelwork, sediment, and visible anomalies without dewatering the reservoir.

Overview

How the service supports asset decisions

Coratia's robotic inspection workflow is designed to help dam owners and engineering teams obtain evidence from areas that are difficult or hazardous to access. Mission planning focuses on the structure, water conditions, operational restrictions, and the observations required for maintenance planning or a specialist structural review.

Typical applications

  • Sluice gates, trash racks, intake structures, and outlet works
  • Upstream faces, spillways, joints, concrete, and submerged steelwork
  • Sediment buildup, obstruction, leakage indicators, and debris
  • Reservoir bathymetry, bed profile, and repeat condition monitoring

Method

Inspection and survey workflow

  1. 01

    Asset review

    Identify drawings, target components, previous findings, operating constraints, and safety controls.

  2. 02

    Inspection plan

    Define ROV access, coverage, imaging, sonar, and measurement requirements.

  3. 03

    Controlled survey

    Capture systematic evidence along the agreed structure and reservoir areas.

  4. 04

    Condition record

    Map observations to components and provide evidence for engineering interpretation.

Outputs

Typical deliverables

  • Component-based video and image record
  • Observed anomaly and obstruction register
  • Sonar, bathymetry, or NDT outputs when included
  • Coverage map and inspection summary

Direct answers

Frequently asked questions

Can a dam be inspected without draining the reservoir?

Yes. ROVs and sonar can inspect many submerged components while the reservoir remains in service, subject to flow, access, operating, and site-safety constraints.

What defects can robotic inspection identify?

The system can document visible cracks, surface damage, corrosion, exposed reinforcement, debris, sediment, leakage indicators, coating condition, and geometric anomalies. Engineering diagnosis depends on evidence quality and specialist review.

Can sonar help in turbid reservoir water?

Yes. Imaging sonar can support navigation and structure assessment when suspended sediment limits camera visibility.
