Other than Full and Open Memo FINAL_Redacted.pdf

This is a Memorandum for the Record documenting a justified single-source acquisition determination under the simplified acquisition threshold. The acquisition is for a Forward and Aft Seal System, AFT Chrome Split Non-Standard Size 670, required for maintenance of a General Fitness Model (GFM) for PSA stem tube seal on the USNS Sojourner Truth. The required delivery date is January 16, 2027, with a period of performance through December 1, 2027. Simplex Americas LLC is the required source and brand name for this item.

The determination identifies three primary justifications for limiting competition: (1) Restrictive Rights – Simplex Americas LLC holds proprietary design and manufacturing rights for the seal system specific to TAO-210 vessels; (2) Exclusive Licensing Agreements – the item is only available from Simplex Americas LLC as the OEM, and MSC lacks the manufacturing and technical information required to reverse engineer or procure alternative replacement parts without compromising reliability; and (3) Standardization – per COMSCINST 4790.3, only the specified Assembly Model SC3 Z-P (Size 630)/SC3 SI (Size 670) maintains the required fleet configuration baseline for all T-AO 205 John Lewis Class vessels. The product is not designated as critical ship equipment. The contracting officer certified the justification as accurate and complete.
