About this file
This Task Group Instruction (TGI) details a specific ship repair task for the USS Blue Ridge (LCC-19) involving the replacement of air escape piping for the clean salt water ballast system. The work is part of a larger ship maintenance project scheduled for January 12, 2026 to May 15, 2027, and focuses on replacing approximately 5 feet of 6-inch Schedule 40 carbon steel piping located in the Clean Salt Water Ballast, Anti-Roll Tank, and Third Deck Weather areas.
The task requires specific technical procedures, including removing existing piping, installing new piping, performing elevated non-destructive testing (ENDT) on weld joints, and conducting an unobstructed air flow test. The Naval Ship Repair Facility and Japan Regional Maintenance Center (SRF-JRMC) will provide government-furnished material, crane and rigging services, utility services, and quality assurance inspections. The material list includes specific components such as steel pipe couplings, backing rings, and piping, with detailed specifications for each item.
