This document is a Job Specification and Engineering Liaison Memorandum for the installation of a blood bank freezer aboard USS TRIPOLI (LHA-7). The primary objective involves removing an obsolete, non-operational blood bank freezer from compartment 01-58 1/2-2-L and installing a newly procured Panasonic MDF-DU502VHA-PA model freezer (NSN 6530017149830) as a permanent replacement. The installation work includes modification of the existing foundation to accommodate the new freezer, removal and reinstallation of ventilation ducts and insulation, reinstallation of joiner bulkhead panels with new sealing compounds and fasteners, CO2 backup piping installation, and operational testing. The anticipated award date is 09/21/2026 with a production completion date of 12/18/2026; the period of performance runs from 10/13/2026 to 01/29/2027.

The scope encompasses detailed technical requirements for removal and reinstallation of auxiliary systems including ventilation recirculation ducts, insulation and lagging, joiner bulkhead panels, and metal joiner door assemblies. Installation requirements reference multiple engineering standards and drawings, including HVAC system diagrams, ventilation and air conditioning assemblies, lighting system wiring, and joiner door specifications. Government-furnished materials include fasteners, sealing compounds, welding materials, insulation components, and piping fittings. The work requires hydrostatic pressure testing of piping systems at 4,050 PSIG, operational testing of the new freezer per manufacturer instructions, and visual inspection of all installed ventilation ducts. The CO2 backup cooling system (MDF-UB7-PW kit) requires installation and testing per detailed procedures provided in the specifications. All work must comply with NAVSEA standards for fabrication, welding, inspection, painting, deck covering, insulation, and cleaning/preservation of surfaces.
