WI 911 Sole Source Signed-redacted rev 01.pdf

This document is a Sole Source Justification Memorandum for the procurement of propeller maintenance parts for the USNS Guadalupe. The document details a sole source acquisition from Rolls-Royce North America, Inc. for preventative maintenance replacement parts for the Propeller System Maintenance (2.5 YR) (SCSI) for the June 2025 ROH (Repair/Overhaul/Handling). The required delivery date/period of performance is from 04/17/2025 to 09/08/2025.

The justification for sole source procurement is based on Rolls-Royce having established proprietary rights, being the sole manufacturer of these specific parts, and having exclusive licensing agreements. The document cites that the Military Sealift Command (MSC) lacks the manufacturing and technical information to evaluate non-OEM service and replacement parts, and that the Original Equipment Manufacturer (OEM) has unique technical expertise and access to specialized parts and certifications required by USCG, ASME, SOLAS, and ABS standards.
