The work involves replacing sea water flushing piping in the 2nd and 3rd decks of the vessel. Specifically, 750 feet of copper piping (ranging from 1/4 inch to 2 inch IPS) will be removed and replaced with new copper-nickel (Cu-Ni) piping. The project scope covers multiple compartments across designated frames (2nd Deck Frame 38 through 48 and 3rd Deck Frame 31 through 42), including CPO work spaces, crew quarters, and master CPO areas. The contract is identified as ICN 38DJ252102 with an anticipated award date of September 11, 2026, a production completion date of December 18, 2026, and a Period of Performance (POP) from October 13, 2026 through January 29, 2027. The preparing activity is SASEBO (Strategic and Sustainment Enabling Base Operations).

Key requirements include removing and installing new piping per referenced standards (including MIL-STD-1627 for pipe bending and specifications 521-7566288 through 521-6123835), cleaning existing valves and hangers for reuse, accomplishing pipe bending and welding per detailed specifications including backing ring fabrication, conducting operating pressure tests with zero allowable leakage, and cleaning and preserving all new and disturbed surfaces. Government-furnished materials include extensive copper-nickel tubing, elbows, couplings, tees, reducing fittings, bushings, unions, O-rings, welding electrodes, brazing alloys, insulation materials, tape, fasteners, flux, and adhesive—itemized across 113 line items in the material list. The work requires submission of a legible condition report from the Marine Chemist to the supervisor and witness pressure testing conducted by the ship's force.
