  1. Improved Flexible Causeway Connector ` Bill Hatch Amphibious Systems Division Naval Facilities Engineering Service Center, Port Hueneme, CA 93043-4370 1/29/02

  2. OPERATIONS IN ELEVATED SEAS REQUIRE SUITABLE CONNECTORS

  3. FLEXIBLE CONNECTOR DESIGN BASIS • A flexible connector is required if lengths > 160 ft. • Driven by loads and operational configurations • Adapt existing NL P-8 end connector to prototype assets • Pipe shear connectors • Flexor tensile connectors • Increase safety and efficiency • Reduce crew involvement in connections • Provide better alignment and engagement • Provide automated flexor locking • Provide automated flexor extension and retraction

  4. ALIGNMENT AND ENGAGEMENT IMPROVED SHEAR CONNECTOR GEOMETRY EXTENDED LENGTH SHEAR CONNECTOR WIDE MOUTH RECEIVER
