RIBS XM-99 Field Study

• 1 1 Ocean Scale XM-RIBS
• Segmented-type designed for ship deployment
• 255 ft legs. 8 ft beam, 24 ft draft
• Launch date May 20, 1999
• Recovery date 4 June 1999
• Location Cape Canaveral, FL
• Instrumentation and Monitoring
• mooring line load cells
• structural steel strain gages
• current meters
• wave gages
• DGPS
• Fixed and flexible joints

• RIBS XM-99 (5/20/99)
• Hsig 2.1 ft, Severe angle of approach

21 May 1999
24 May 1999

• RIBS XM-99 (5/21/99)
• Hsig 2.5 ft, Anticipated angle of approach

14
Lessons Learned

• Structure must be constructed of flexible
  materials (bends but doesnt break)
• Moving parts (connections) must be minimized
• Theoretical Performance Equations were validated
  by field results
• Performance of RIBS during off angle wave
  approach was better than expected
• Mooring performed well

15
HYDROBEAM RIBS

• SURVIVABILITY
• PORTABILITY (COULD BE TRUCKED)
• INTERCHANGEABLE MODULES TO MAKE UP EACH LEG

technologies

• The Helical AnchorA versatile, mechanically
  deep set anchor offering massive and certifiable
  holding power with zero drag.
• SeaflexA reinforced, energy absorbing
  elastometric cord with unprecedented and reliable
  shock attenuating capability.
• SpectronA high strength polymer that is, pound
  for pound, ten times stronger than steel. It
  backs up the Seaflex to complete a resilient,
  powerful link.

25
PLANS BEYOND FY 2000
