ALEX HALEY SSDG REPOWER_Sources Sought Notice.pdf

Title: Procure 3 Generator Sets for Maritime Service, Retrofit.

APFS Number: P2025069851

This announcement is a Sources Sought Synopsis (market survey). This is not a Request for Quote (RFQ) or a Request for Proposal (RFP). This announcement is for information and planning purposes only and is not a commitment by the Government, implied or otherwise, to issue a solicitation or award a contract.

The purpose of this Sources Sought Synopsis is to determine interest and capability of potential businesses. The Government may use responses to this Sources Sought Synopsis to make an appropriate acquisition decision for this project.

The U.S. Coast Guard intends to purchase and install 3 modern generator sets to replace aging assets in service on board CGC Alex Haley. The existing generator sets are (quantity 4) 300 kW machines of an obsolete design, which is currently not well-supported. New generator sets will need to fit and be adapted during install to the existing fuel, exhaust, and cooling systems. A quantity of 3 new generator sets is requested at a minimum capacity of 350 kW per generator, reliability and supportability will be an important factor for the proposal to be developed.

The CGC Alex Haley (WMEC-39) is homeported in Kodiak, AK 99619. The CGC Alex Haley is 282 feet long, 59 feet wide, drafts 17 feet (at full load), and weighs 2,592 long tons (at full load).
