About this file
This is a Job Specification document for shipboard maintenance work on the USS PATRIOT (MCM-7), a Navy vessel. The work involves replacement of seawater pump discharge piping for the 1A Main Propulsion Diesel Engine (MPDE) located in the Main Machinery Room (3-63-0-E) at Sasebo.
The scope requires removal and installation of one 2-1/2 inch IPS seawater pump discharge piping assembly (approximately 2 feet long) with mechanical joint ends, fabricated from CRES (Corrosion Resistant Steel), Schedule 40 material. All materials must be non-magnetic. Key requirements include: recording permeability test results for existing and new metallic materials using SRF YOKOSUKA 4121/1; cleaning bilge areas to gas/oil free condition per 29 CFR 1915 Subpart B with Marine Chemist certification; templating and assembling new piping per ENCLOSURE (A) and standard references 009-012 and 009-032; fabricating backing rings per specification; and witnessing an operating pressure test conducted by Ship's Force with zero allowable leakage tolerance. The government furnishes all materials including tube assembly, O-rings, elbows, pipe, and welding electrode (MIL-316L). The anticipated award date is 9/20/2026 with production completion by 10/29/2026 and Period of Performance from 9/28/2026 through 12/31/2026. The work is prepared by A. Hamada, approved by S. Murakami, and concurred by T. Takamasu at Preparing Activity SASEBO.
