This announcement seeks out technologies and methodologies to regarding underwater power systems, including deep submergence batteries. NAVFAC ESC is seeking to identify qualified sources which offer potential for advancement and improvement of Navy and Marine Corps operations through the development of large capacity (e.g., 1.0 Megawatt-hours) deep-ocean uninterruptible power supplies (UPSs). To be eligible for consideration and possible contract award, the technology or methodology shall be in either basic research (Category 6.1), applied research (Category 6.2), advanced technology development not for a specific system/hardware (Category 6.3A), or demonstration and validation (Category 6.3B). Furthermore, the technology or methodology shall address the following performance areas.

2.1 Operational Pressure Range : 0 psig to 4,500 psig.2.2 Operational Temperature Range: -3.0 ?C to +50.0 ??C (27 ?F to 122 ?F).2.3 Design Service Life: Five (5) Years.2.4 Nominal Input Voltage: Variable, 250 to 400 Vdc (375 Vdc nominal).2.5 Nominal Output Voltages: Configurable to support a range of low voltage direct current busses, for example 24, 36, 48, and 60 Vdc.2.6 Internet Protocol (IP) Compatibility: The UPS system will provide IP-compatible "smart" battery management capabilities that will enable remote control via local area network (LAN).2.7 Standard Marine Connector Compatibility: The UPS system will be compatible with standard marine connectors, both wet-mate (e.g., ODI Nautilus, SeaCon CM2000, or equivalent) and dry-mate (e.g., SeaCon MINI-CON, or equivalent).
