About this file
This Task Group Instruction (TGI) details a naval maintenance project for the USS Blue Ridge (LCC-19) involving the replacement of Collecting, Holding, and Transfer (CHT) discharge piping. The work involves replacing approximately 60 feet of 4-inch CHT discharge piping, transitioning from existing Cu-Ni 90-10 material to Cu-Ni 70-30 material, located in crew washroom and decontamination stations between frames 99 and 100 on the port side. The project is classified as a Class P-2 piping replacement with Level III cleanliness requirements, with a planned contractor work period from July 21, 2026 to November 21, 2027. The U.S. Fleet Forces Command (SRF-JRMC) will provide government-furnished materials and supporting services including crane rigging, utility services, and quality assurance inspections.
The material list includes multiple copper-nickel tubes, elbows, sleeves, and backing components, with specific stock numbers and quantities specified for procurement. Special requirements note potential asbestos and lead hazards during the work. The project involves detailed technical specifications, including hydrostatic testing at 60 PSIG using clean fresh water, and will be executed under Job Control Number ER01-3539. The task is intended to clear a specific Depot Facility Submission (DFS No. LCC-19-0023-2024) and involves coordination between multiple departments and personnel, including a planner from Code 234 and a Work Integration Manager from Code 333.
