About this file
This document is a Task Group Instruction (TGI) for repair work on the USS BLUE RIDGE (LCC-19), specifically addressing corrosion repair of structural members in the 9-44-0-Q compartment on the starboard side. The TGI details the repair of two specific structural components: a bulkhead plating on Transverse Bulkhead Frame 44 and a Transverse Oiltight Floor Frame 45, both made of OS, MIL-S-22698 GR-A plate material.
The work is scheduled for contractor execution from January 12, 2026, to May 15, 2027, with specific requirements including build-up welding of corroded areas, personnel safety protocols, and surface treatment. The repair locations are in multiple compartments including the Underwater Log and Fathometer Trunk, Distillate Fuel or Ballast area, and Pump Room No. One. Supporting services will be provided by SRF-JRMC, including crane and rigging services, utility services, safety inspections, and quality assurance inspections. The TGI is part of a larger ship repair and maintenance project for the USS BLUE RIDGE at Commander, Fleet Activities Yokosuka Naval Base.
