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

  • 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

Needs - Preliminary

  • Navigation

    • re-positioning accuracy

    • 3-D mapping into CAD

  • High quality images

    • visual, sonar

  • Image scaling

    • deterioration assessment, design solutions

  • More thrust

    • currents, cable towing


Suggestions

Suggestions?

  • Other case studies

  • New imaging/navigation technology

  • Other applications

    • cleaning, painting, debris removal, hazardous cleanup, levee inspections
