1. NAVAL LIGHTERAGE R&D PROGRAM 30 JANUARY 2002 Sealift Support Program Office Naval Facilities Command

2. 2 AGENDA ACTD Lesson’s Learned Navy R&D Accomplishments Plans For Next 12 Months Replacement System Questions?

3. 3 ACTD LESSON’S 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. 4 NAVY LIGHTERAGE R&D 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. 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

6. 6 IMPROVED RIGID CONNECTORS

7. 7 ALIGNMENT/CAPTURE DEVICE

8. 8 FLEXIBLE CONNECTORS Required every 160’ to reduce sea state loads 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

9. 9 NEW GENERATION DECK WINCH Prototype procurement by NSWCCD Philadelphia (NAVSSES) Manufacturer – InterOcean Systems Company, San Diego, CA Delivery scheduled Feb 02 At-sea testing scheduled Mar 02 Replaces obsolete deck winch on SLWT –Same footprint –Increased load to 30,000 lbs –Increased capacity –Increased wire rope size to 1-1/4” –Larger and stronger capstan –Quieter

10. 10 NEXT GENERATION DECK WINCH

11. 11 ARTICULATING A-FRAME Designed by NFESC and NAVSSES Provides extension from 3 feet aft of WT bow to 5 feet forward of bow Improves operator safety Increased rated load to 30,000 lbs

12. 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. 13 WARPING TUG/CF POWER MODULE One piece unit 24’W x 8’H x 90’L WT and CFPM use similar hull form and propulsion system 2X more power than existing units Bow thruster to provide better maneuverability (WT Only) Improved handling –Pusher pads, better fendering, hogging-in winches (WT Only) Calculated maximum craft speed full load: 11 KTS Current module weight estimates – WT 121 LT, CF 119 LT
