Robotic No-Man-Entry Sludge Storage Tank Cleaning

I&T Wish Robotic No-Man-Entry Sludge Storage Tank Cleaning
(REF: W-0603)
Matched I&T Solution
Trial Project
Summary and Challenges
  • Core Technology Mechanisms: Remote-controlled or track-driven robots.
  • Tools: Equipped with cutters, claws, high-pressure nozzles, and vacuum systems.
  • Operational Challenges Low Visibility: Opaque sludge renders standard cameras ineffective when splashed.
  • Physical Hazards: Internal obstacles can trap or flip units.
  • Connectivity: Steel walls block wireless signals, requiring heavy physical tethers.
  • Engineering: Robots need high torque for "sticky" sludge but must remain small enough to fit through standard manways.
  • System Complexity: Success depends on surface "recycling" plants capable of processing massive waste volumes in real-time.
Expected Outcome
  • Tiny and zero risk and cleaning efficiently in confined space
Expected Trial Duration 12-month
