1.2.2 N6275843277472 JA_redacted.pdf

This is a Sole Source Justification and Approval (J&A) document for the procurement of a Stern Tube MX9 Shaft Seal Assembly (Item H72252-01) for the Ship Repair Facility and Japan Regional Maintenance Center (SRF-JRMC) in Yokosuka. The procurement will be conducted under FAR Subpart 13.5 Simplified Procedures for Certain Commercial Items, with Naval Supply Fleet Logistics Puget Sound (N00406) as the contracting activity.

The J&A establishes Wartsila Defense Inc. (DMS) as the sole source provider, as they are the Original Equipment Manufacturer (OEM) with cage code 0SYN4, operating under cage code 0EYA6. The component is critical for maintaining watertight integrity of the ship's propulsion system, with failure risks including leakage exceeding 1.6 gallons per minute. Market research, including searches on SAM.gov and other procurement websites, confirmed no other authorized distributors exist for this OEM-restricted component. The part is assigned National Stock Number (NSN) 2040-01-472-9265 but is no longer stocked. The procurement will be a firm fixed-price supply contract awarded directly to DMS, as they have no authorized distributors and sell directly to the government.
