Hot Oil Flush of the External Hydraulics System

Background
The Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility (PHNSY & IMF) is conducting market research to identify eligible contractors capable of providing hot oil flushing services for the External Hydraulics System onboard a Los Angeles-class submarine. This sources sought notice aims to gather information on potential contractors who can meet the requirements outlined in the Statement of Work.

Work Details
The contractor will be responsible for performing hot oil flushing on various flush loops of the External Hydraulics System, including but not limited to: Secondary Propulsion Motor, Power Plant, Retractable Bow Planes, Thin Line Towed Array, Sail, and Vertical Launch System hydraulics. Key tasks include:

1. Providing flushing equipment that meets specified flow and pressure ratings.
2. Coordinating with Shipyard Engineering & Planning Department (EPD) to identify attachment points.
3. Inspecting the External Hydraulics System and specific flush loops to ensure integrity before flushing operations.
4. Conducting tightness tests for each flush loop prior to operations.
5. Ensuring filter media achieves required oil cleanliness levels.
6. Generating a Process Control Procedure for flushing operations, including detailed diagrams and descriptions of equipment and procedures.
7. Performing hot oil flushes for each specified loop and submitting reports detailing results and analyses to the supervisor.

Period of Performance
The contract will be performed over a period that aligns with the operational schedule of the Pearl Harbor Naval Shipyard, with specific timelines to be determined based on project requirements.

Place of Performance
Pearl Harbor Naval Shipyard & IMF, Hawaii.

Bidder Requirements
Interested contractors must demonstrate capability by providing a tailored capability statement that includes documentation supporting claims for equipment and staff capability, as well as any previous experience similar to this effort. Contractors must also have the necessary equipment to perform hot oil flushing within specified parameters.

Incumbent Analysis (see Incumbents section for more detail)
This opportunity appears to have a confirmed incumbent and/or closely related prior contract based on recent hot oil flushing work performed for similar shipboard systems. For example, Oilkleen performed “HOT OIL FLUSH USS RUSHMORE” (N0040626P0002) valued at $376,970 during 11/25/25–01/12/26, and Sumitomo Heavy Industries supported “USS RUSHMORE (LSD-47) … NO.4 SSDG ENG HOT OIL FLUSHING ACCOMPLISH” (N6264921G0002–N6264926F0108) valued at $236,584 during 01/16/26–06/30/26. The prior efforts appear similar in that they involve executing hot oil flushing operations aboard naval vessels, including associated preparation/testing and reporting consistent with the external hydraulics flush loops described for this Los Angeles-class submarine.
