The Department of Commerce, specifically the National Oceanic and Atmospheric Administration (NOAA), is seeking qualified contractors for the repower and modification of the NF4 dive boat, a 3 HRIB Northwind Dive boat associated with the NOAA Ship Nancy Foster. The project aims to replace the current marine engine, a Cummins QSD 4.2L 320 EI, which has become increasingly difficult to service due to discontinued production and limited availability of spare parts. This procurement is critical to ensure reliable operation and maintenance support for the dive boat, which plays an essential role in NOAA's marine operations. Interested small businesses are encouraged to contact Isaac Bright at ISAAC.BRIGHT@NOAA.GOV or (541) 283-5107 for further details, as this opportunity is set aside for total small business participation under FAR 19.5.
