AGENDA

• ACTD Lessons Learned
• Navy RD Accomplishments
• Plans For Next 12 Months
• Replacement System
• Questions?

3
ACTD LESSONS LEARNED

• ISO sized modules increased weight/assembly time
• Structure needed to be strengthened for SS5
  survivability
• Needed to improve alignment guides
• Flexible connections required for larger
  platforms
• Rigid connectors required strengthening and
  safety improvement
• Additional fendering required for safety
• Mooring and anchoring improvements required
• Additional speed and bollard pull required
• Deck jewelry and increased winch capacity
  required
• Interface with legacy systems critical
• Bow ramp deployment improvements required

4
NAVY LIGHTERAGE RD ACCOMPLISHMENTS

• Designed improved rigid connector
• Automated development of flexor connector
• Designed alignment wedge for improved assembly
• Reduced weight by complete redesign of modules
  and alternate material evaluation
• Increased module strength based on hydrodynamic
  analyses/modeling
• Improved power module with fendering, deck
  jewelry, and deck winch upgrades
• Improved platform speed and bollard pull by
  optimizing hull form, propulsion system, and
  reducing weight
• Manufacturing 3 prototype modules for test at sea

5
IMPROVED RIGID CONNECTORS

• Designed by NSWCCD Carderock
• Remote activation/manual backup
• Improves safety through SS3
• Provides greater load transfer to hull
• Fabricated by CG Yard
• Load tested at NSWCCD Oct-Nov 01
• Government patent pending
• Incorporates all ACTD lessons learned
• SS5 survivable
• Incorporated in 3 prototype modules
• NSWCCD developing alignment/capture device works
  in conjunction with connectors to assist
  connection process

• Sea State 5 survivable
• Designed by NFESC from existing NL flexor
  connectors
• Includes remote activation/manual backup
• Adapted shear connection as alignment device
  for high
• sea states
• At-sea testing scheduled Mar Apr 02

10
NEXT GENERATION DECK WINCH
11
ARTICULATING A-FRAME

• Designed by NFESC and NAVSSES

  feet forward of bow
• Improves operator safety
• Increased rated load to 30,000 lbs

12
SPANNING RAMP

• Concept development by NFESC
• Must permit rolling stock to move between
  platforms and craft
• Must be self contained, packaged in ISO flat-rack
• Must be Sea State 3 capable
• Must ensure ramp break-over angle permits traffic
  by all vehicles

13
WARPING TUG/CF POWER MODULE

• One piece unit 24W x 8H x 90L
• WT and CFPM use similar hull form and propulsion
  system

  (WT Only)
• Improved handling
• Pusher pads, better fendering, hogging-in winches
  (WT Only)

NON-POWERED MODULE TYPES

• 8W x 8H x 40L ISO modules too lively/heavy
• Redesigned to larger 24W x 8W x 80L to reduce
  weight and improve safety/assembly
• Four Non-powered module types
• Bow ramp
• Combination (male/female)
• Intermediate
• Ramp
• Improved rigid/flexor connectors and alignment
  wedge

18
BOW RAMP MODULE

• 24W x 8H x 80L
• In concert with flexible connectors and hull
  shape, will provide for dry ramp on a 150 beach
  gradient
• Module will provide a bow thruster for greater
  maneuverability around vessels and control in
  cross-current
• Ramp break-over angle will permit all vehicles to
  transverse without incident
