About this file
This document is a WebAIM Short Form Task Group Instruction (TGI) for the USS Blue Ridge (LCC-19), specifically focused on the Firemain System Tightness and Operational Test. The TGI is dated 03-MAR-2025 and is associated with Task Group Instruction Number 52111-3-300KTR, with a project system number of 52111. The document outlines detailed inspection requirements for mechanical, welded, and brazed joints of the Firemain System, requiring visual inspections at Normal Operating Pressure (NOP) and Normal Operating Temperature (NOT) to ensure no external leakage for a minimum of 30 minutes, with no permanent deformation of joints allowed. The instruction involves work tasks for contractors, quality assurance, and ship's force personnel, each with specific visual inspection responsibilities, and references two key documents: an Expanded Ship Work Breakdown Structure and an Engineering Operational Sequencing System (EOSS) for system setup and verification.
