outline
Outline
  • Project description
  • Case study approach
  • Mobile District
  • Other case studies
  • Suggestions
objective
Objective
  • Help adapt robotic technologies to reduce costs and improve safety of inspections and maintenance in COE navigation, flood control, and hydropower applications
  • $125k FY06
  • Work started Mar 06
approach
Approach
  • Compile case studies of robot use in COE Civil Works applications
    • Project description, needs addressed
    • Robotic technology used
    • Outcomes
    • Cost-benefits & safety improvements versus traditional methods
    • Overall assessment
    • Contacts (COE, industry)
  • Survey robotic technologies for best-fit with COE needs
  • Identify technology demonstration for FY07, select site, and scope demonstration project
products
Products
  • White paper on potential for robotic technologies in COE Civil Works applications
    • Summarize COE needs
    • Compile existing robotic capabilities
    • Summarize case studies & lessons learned
    • Identify technology gaps
    • Develop R&D plan to increase robot utilization
    • Estimate potential cost-benefit and safety improvements
  • Case study archive
erdc crrel role
ERDC-CRREL Role
  • Agent to compile and disseminate case studies, inform District personnel of opportunities and appropriate technology
  • Technical assessments, cost-benefit analyses, R&D to fill gaps
  • Honest broker to link industry capabilities with District needs
case studies
Case Studies
  • Existing COE applications - ROV’s
    • Lock & dam, hydro facilities
    • Equipment, frequency, type of use
    • Cost & safety benefits vs alternatives
    • How was ROV originally justified?
    • Future use & capabilities needed
    • Cost/benefit analysis can help District justify & expand use

Mobile District – Millers Ferry
  • POC: Jeff Byars ROV: VideoRay Site visit: 11-12 April 06

  • ROV use
    • Inspection of conduits
    • Debris location/removal on stop log sills (~10 times/yr)
    • Inspection and clearing of turbine service gate seats
    • Recover of submerged debris
    • Recovery of sunken floating moorings
    • Checking beaches before opening for season
    • Inspection of turbine wicket gates
  • Much faster mobilization than divers
  • Tight access no problem
  • Safety & administrative benefits
  • ~ $70k/yr savings vs divers (+ ad hoc inspections)
  • ROV cost ~ $30k
other case studies
Other Case Studies
  • Sault Ste. Marie
    • 2 – 4 May 06
    • Lock, dam & hydro facilities
    • ROV: 10+ yrs old, want new one (inspections & surveys)
    • POC: Ed Hallquist
  • Seattle District
    • mid-May 06
    • 7 lock, dam & hydro facilities
    • ROV: Deep Ocean Phantom
    • POC: Dennis Fischer
  • Chelan County Public Utility District
    • mid-May 06
    • 2 hydro facilities
    • ROV’s: Deep Ocean Phantom & custom ROV
needs preliminary
