This is a WebAIM Short Form Task Group Instruction (TGI) for maintenance work on the USS RAFAEL PERALTA (DDG-115), a U.S. Navy destroyer. The document, issued January 30, 2026, authorizes dewatering of Fuel Tank Groups 5 and 6 with a work window from August 3, 2026 to September 11, 2026.
The scope involves removing water from six fuel tanks located across multiple ship compartments: Crew Living Spaces 4, 6, and 7; an Access Trunk; a Passage; and a Generator Room. Group 5 consists of three tanks with a combined capacity of 69,695 gallons requiring removal of 47,700 gallons of water, while Group 6 contains three tanks with a combined capacity of 63,450 gallons also requiring 47,700 gallons of water removal. Work will be performed in accordance with Navy standard procedures (references 099-909YO and 009-009). The instruction specifies that SRF-JRMC will provide supporting services including crane and rigging, electrical utilities, low-pressure air/water/steam supply, safety and gas-free inspections for employees, and QA inspection. A related Fuel Transfer Valve replacement (TGI No. 38K6154103A01) will occur concurrently. The planner is Code 231B A. Suzuki and the Work Integration Manager is Code 333 T. Yaginuma. No Government-Furnished Material is required, and the security classification is unclassified. The document contains blank fields for task descriptions, materials lists, and crew hour requirements.
