Dam, Reservoir & Intake 3D Surveys
3D digital models of freshwater intake towers, spillways, and hydro-turbine trash racks, without putting divers into hazardous flows.
What This Involves
Intake towers, spillway faces, and turbine trash racks sit in flow conditions that make diver inspection genuinely hazardous — intake suction and spillway discharge are exactly the environments remote survey exists for. We generate full 3D digital models of the submerged structure using ROV-based photogrammetry and sonar, giving the operator an inspection record without putting a person into the water near an active intake or spillway.
How It's Done
Flow and hazard assessment to confirm remote survey approach and any required shutdown/isolation coordination
ROV-based photogrammetric and sonar survey of the intake, spillway, or trash rack structure
3D reconstruction of the submerged structure
Findings reported against the operator's asset integrity programme
Deliverable
A 3D model of the submerged intake, spillway, or trash rack structure, captured without diver exposure to hazardous flow.
Who It's For
Hydro operators and reservoir authorities with a diver-hazardous inspection requirement.
