Stern tube shaft insert face

Fleet Logistics Center Puget Sound is seeking to procure a STERN TUBE SHAFT INSERT FACE as a brand name only requirement from OEM Wartsila. The Department of the Navy Naval Supply Systems Command will utilize FAR Part 12 and 13.5 procedures for this unrestricted procurement, with a commercial, firm fixed-price supply contract anticipated to be awarded. The solicitation N0040625QS363 is scheduled to be posted on sam.gov on or about July 15, 2025, with quotes due on or about July 21, 2025. All prospective offerors must be registered in the System Award Management (SAM) database prior to submitting offers, during performance, and through final payment, as lack of registration will make vendors ineligible for award. The government files indicate this is a sole source justification for a Replace #4 Stern Tube Seal for Navy vessels, with evaluation based on the brand name requirement and contractor qualifications.

This procurement does not utilize any set-aside designations and is being conducted as an unrestricted competition, though the brand name requirement effectively limits participation to Wartsila Defense, Inc. as the sole manufacturer. The attached government documentation confirms that Wartsila Defense holds exclusive intellectual property rights for this proprietary part (P/N: US-70589-1 ITEM 24, NSN: 2010-01-283-1507) and is the only source capable of providing the material due to unique form, fit, and function requirements. The procurement falls under NAICS code 336611 for Ship Building and Repairing and PSC code 2010 for Ship and Boat Propulsion Components. The document indicates this is a direct replacement part for existing Navy vessel equipment, with Wartsila serving as an authorized distributor. No award values, budget ranges, or specific quantities are disclosed in the pre-solicitation notice, though the firm fixed-price contract structure suggests a defined scope of supply.
