Notice of Intent to Sole Source - Stretch Mooring

The contract involves replacing two stretch hoses with two flange adapters each to sustain the operational capabilities of existing moored data buoys. These moorings must directly integrate with the pre-existing system, which consists of a bungee-like cord containing electrical wires designed to secure meteorological buoys while facilitating power and data transmission between the buoy surface and instruments below. The stretch hoses are made from reinforced rubber using elastomer-synthetic composite technology, enabling them to stretch up to 1.5 times their original length. This design provides a stable platform and acts as a mechanical isolator, minimizing interference between the surface buoy and quieter lower mooring sections. Additionally, the hoses are embedded with multiple electrical conductors and twisted pairs to ensure reliable signal and power transfer along their length. The mooring system employs bolted flange connections to reduce mechanical noise and promote a modular design approach. The contract is issued by the Department of Commerce, NOAA, under solicitation number 1333MJ26Q0011, with a response deadline of June 12, 2026. The work is associated with NAICS code 335999, and the primary point of contact is Michelle Brebnor at NOAA's Kansas City office.
