The Department of Commerce, specifically the National Oceanic and Atmospheric Administration (NOAA), is seeking qualified small businesses to repower and modify the NF4 dive boat, which is currently attached to the NOAA Ship Nancy Foster. The project involves replacing the existing Cummins QSD 4.2L 320 EI marine engine, which has become difficult to maintain due to discontinued production and limited availability of spare parts, with a new engine that offers improved maintenance support and a reliable supply of parts. This repower is crucial for ensuring the operational readiness and efficiency of the dive boat, which plays a significant role in NOAA's marine research and exploration activities. Interested parties should contact Isaac Bright at ISAAC.BRIGHT@NOAA.GOV or (541) 283-5107 for further details, as this opportunity is set aside for small businesses under the SBA guidelines.
