Notice of Intent to Sole Source - Stretch Mooring

The National Oceanic and Atmospheric Administration (NOAA) is seeking to purchase two 15-meter Stretch Electro-Mechanical (EM) cables for their Observing Systems and Advanced Technology (OSAT) branch. These cables are necessary for maintaining the continuity and reliability of real-time data streams from offshore buoys. The cables must have a specific set of technical specifications, including a 6061-T6 aluminum termination, rubber compound, and copper conductor wire. The cables will be used to secure real-time observing buoys while providing a robust transmission link for 2-way power and Ethernet communications between the surface buoy and subsurface instruments. Key features of the required cables include: • Material: 6061-T6 Aluminum Termination • Rubber Compound • Copper Conductor Wire • Conductor Arrangements: 8 x 22 AWG, 4 x Twisted Pairs 24 AWG • Conductor Terminations: 22 AWG: MCIL8s w/ corresponding locking sleeves • 24 AWG: DIL8s w/ corresponding locking sleeves • Male connectors on one end, female on the other • Male locking sleeves on male connectors • Female locking sleeves on female connectors • Length: 2 x 50ft • Working Load: 900kg • Maximum Elongation: 1.5X standard length • Voltage Range: Up to 480V • Data Rate: Up to 100 Mbps • Flange/Bolt Pattern: 6 x 4.5" diameter x 0.5" bolt pattern • Design Life: 5-7 years
