1.01g TSV4 Narragansett Gauge List Exp AUG25.xlsx

This is a gauge calibration list for the USNS Narragansett, documenting 244 measurement instruments across multiple ship systems requiring periodic calibration and maintenance. The spreadsheet tracks serial numbers, instrument models, manufacturers, calibration dates, due dates, nomenclature, pass/fail status, and physical locations throughout the vessel. The majority of instruments were last calibrated on August 28, 2023, with calibration due dates of August 28, 2025. Most instruments show "PASS" status, indicating they meet calibration standards, and are distributed across key operational areas including the bridge, engine control room, main switchboard, engine rooms, pump rooms, and machinery spaces.

The list identifies critical deficiencies requiring immediate attention: 153 instruments require calibration (marked "NO CAL"), three instruments have expired calibrations dating to 2017-2020, one instrument shows a broken status (rudder angle indicator), and one instrument is missing entirely (auxiliary A/C salt water temperature output gauge). Notable instruments requiring calibration include RPM gauges, pressure switches, temperature controllers, and specialized monitoring equipment for the main propulsion diesel engines, controllable pitch propeller systems, air conditioning units, and refrigeration systems. The expired instruments include a starboard main propulsion engine temperature controller and several pressure and temperature switches on both port and starboard main propulsion engines, representing potential compliance and safety risks that align with the referenced federal solicitation for calibration services (N0018926QL018).
