Hydro dam & reservoir surveys

Underwater inspection and spatial survey datasets for hydro dam, reservoir and water infrastructure assets. ROV NZ has completed surveys for several clients with these assets.

Discuss your project

Inspect underwater infrastructure

ROV visual and sonar-assisted inspections provide recorded evidence of accessible underwater assets. We plan the inspection around the structure, operating conditions, access and the questions your engineering team needs answered.

Survey reservoir and underwater terrain

USV 3D sonar surveys can produce georeferenced point clouds, bathymetric surfaces and contours for reservoir and shallow-water terrain. Coordinate systems, vertical datums, coverage and acceptance criteria are agreed before mobilisation.

Combine inspection and spatial information

Where appropriate, we combine ROV inspection, subsea photogrammetry and USV survey data to document both asset geometry and surrounding underwater terrain. Deliverables can include LAS or E57 point clouds, surface models, inspection footage and agreed reports.
