NOAA’s Office of Marine & Aviation Operations requires a total small-business set-aside contractor to remove the NOAA Ship Reuben Lasker’s aging Furuno Felcom GMDSS and procure, install, and commission a new Iridium LT-3100S GMDSS, with a brand-name requirement for Lars Thrane Communications Systems. The vendor must be an authorized Lars Thrane distributor/reseller and a Coast Guard-designated GMDSS Shore Maintenance Provider, and the work must satisfy ABS GMDSS certification and Buy American-Supplies requirements. Performance/delivery is to the Reuben Lasker’s San Diego home port dock at the Unified Port of San Diego 10th Ave. Marine Terminal, 1839 Water St., San Diego, CA, during October–November 2026. Offerors must provide technical approach, past performance references, pricing, SAM registration/UEI/CAGE, authorized OEM letter, insurance, and country-of-manufacture verification. Evaluation is a trade-off based on technical approach, past performance, and price, with non-price factors significantly more important than price; award is intended as a single firm-fixed-price purchase order on an all-or-none basis with Net 30 payment terms.
