1. Operational Challenge
Port jetty piles experience severe splash-zone marine growth and tidal corrosion. Propeller suction from harbor ships prevents human diver entry.
2. Robotic Solution & Deployment
Deployed heavy-duty ROV Titan equipped with subsea rotary cleaning brushes and Ultrasonic Thickness (UT) probes to measure steel wall thickness without halting harbor traffic.
3. Technical Methodology
ROV Titan cleared biofouling on selected inspection points and pressed UT sensors against steel piles to stream real-time wall thickness logs.
4. Execution Workflow
5. Project Results & Impact
Inspected 80 steel jetty piles, identified 5 critical piles with >35% thickness loss, and enabled targeted cathodic sleeve installation.

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.
