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