1. Operational Challenge
Pumped Storage Projects (PSP) have deep water shafts, high pressure intake tunnels, and concrete penstocks operating under extreme hydraulic heads inaccessible to human divers.
2. Robotic Solution & Deployment
Deployed deep-rated ROV Volt with high-intensity LED illuminators and sonar to inspect intake gates, shaft concrete lining, and penstock valve seals.
3. Technical Methodology
The ROV navigated down 150m vertical intake shafts using fiber-optic tethers to stream HD video and sonar geometry of penstock liners.
4. Execution Workflow
5. Project Results & Impact
Completed structural inspection of upper/lower PSP reservoirs and penstocks, confirming gate seal integrity and catching concrete cavitation early.

Cooling Tower Sump Inspection
Cooling tower sumps are confined underwater environments where conventional inspection methods often involve significant safety risks and operational challenges. Draining sumps causes massive refinery downtime costing millions, while manual diver entry is hazardous due to chemical presence and active suction.
Water Storage Tank Inspection
Drinking water reservoirs require periodic structural audits. Draining tanks disrupts municipal supply lines and wastes millions of gallons of treated water, while diver entry risks drinking water contamination.
Bridge Piles Inspection
Bridge pile foundations undergo intense river currents and underwater scour. Mud-heavy waters render visual diver checks ineffective, and swift currents endanger human divers.
