About this file
This is a Task Group Instruction (TGI) document for inspection and preservation work on the USS HOWARD (DDG-83) vacuum collection holding tank room. The work involves ultrasonic thickness measurements and preservation of tank top plating in Room No. 2 (4-300-0-E), covering 96 SF of tank top plating between Frames 300-308, one bilge drain well, and 170 SF of vertical surface plating up to 6 inches from the tank top.
The contractor must pump out, clean, and dry the spaces; perform ultrasonic thickness measurements using specific grid patterns (12"x12" for tank top, 6"x6" for bilge drain); and accomplish preservation requirements per specification 009-32. The work period is from March 31, 2025 to August 19, 2025. The document includes technical specifications, measurement requirements, and details about government-furnished services including crane operations, utilities, and inspection services. The work area contains potential asbestos hazards and requires special safety considerations. A detailed sketch shows the plan view of the preservation area and bilge drain well assessment locations.
