About this file
This is a WebAIM Short Form Task Group Instruction (TGI) for shipboard maintenance work on USS RAFAEL PERALTA (DDG-115). The document provides detailed specifications for preserving the No. 3 Ship's Service Gas Turbine Generator (SSGTG) intake and exhaust trunk systems.
The work scope encompasses preservation of 1,100 square feet of interior structural surface in the SSGTG Exhaust Trunk (1-370-2-Q) on the main deck, 01 level, and 1,370 square feet in the SSGTG Intake Trunk (1-388-2-Q), excluding areas behind bolts, nuts securing the moisture separator, and louvers. Work locations also include the Passage (1-377-0-L), Aviation Repair Shop (1-381-0-Q), and Generator Room (3-370-0-E). The contractor work start date is July 27, 2026, with completion required by September 4, 2026. The initial condition notes a Critical Coated Area (CCNY-DDG115-002-26) and potential asbestos hazard requiring appropriate safety measures and personnel accountability procedures. The work must comply with Gas Turbine Maintenance Procedure references and specific coating requirements outlined in Tables 22A and 18A. Government-furnished materials include various insulation products, acoustic materials, fasteners, adhesives, connectors, and rubber sealing materials, with SRF-JRMC providing crane services, utilities (electrical, water, steam), safety inspections, gas-free inspections, and quality assurance inspections for coating application. The instruction was prepared by M. Hayashi (Code 231B) and approved by R. Takagi (Code 231B) on November 24, 2025, under ICN 38K6112316.
