TJ-437D-01 Tank Level Indication System.pdf

This document is a technical specification for a Tank Level Indication System (TJ-437D-01) for the NOAA Ship Thomas Jefferson drydock maintenance project. The specification details the requirements for a tank level indication system that monitors and displays liquid levels in shipboard tanks, establishing performance standards, physical dimensions, and operational parameters necessary for maritime vessel operations.

The specification establishes functional requirements for accurate tank level measurement across multiple tank types aboard the vessel, including capacity for various tank sizes and liquid types. It defines technical performance criteria such as measurement accuracy, response time, display visibility, and environmental operating conditions (temperature, humidity, vibration) consistent with marine vessel standards. The system must integrate with existing shipboard infrastructure, meet corrosion resistance requirements for saltwater environments, and comply with applicable maritime regulations and safety standards. Installation, testing, commissioning, and training requirements are included to ensure proper operational integration with the Thomas Jefferson's existing systems during the FY27 drydock maintenance period coordinated by the National Oceanic and Atmospheric Administration.
