About this file
This is a WebAIM Short Form Task Group Instruction (TGI) for shipboard maintenance work aboard USS RAFAEL PERALTA (DDG-115). The instruction, prepared on November 29, 2025, and dated January 21, 2026, directs the installation of a 1A Gas Turbine Module (GTM) Moisture Separator Bonding Strap with work occurring in Intake Engine Room No. One Dirty Side (compartment 02-174-1-Q), Passage (01-118-1-L), and Deck Gear Locker (01-174-1-A). The work involves installing one bonding strap assembly of corrosion-resistant steel (CRES Type-I, Standard Size B per MIL-DTL-24749C) with a welded attachment using a 1/8 inch fillet weld to a CRES 316L boss on the 02 Level Deck Plating, per MIL-STD-22D weld joint design specifications.
The contractor work period runs from October 26, 2026 through December 4, 2026, with an estimated 24 hours of FOD (Foreign Object Debris) Protection work required. The instruction identifies an initial hazard condition involving potential asbestos exposure. Government-furnished material will be provided by SRF-JRMC, along with support services including crane and rigging, electrical utility, low pressure air/water/steam supply, safety and gas-free inspections for SRF-JRMC employees, and quality assurance inspections. The material list specifies four items including bonding strips, screws, sleeves, and insulation materials to be ordered for the contractor. References include the Gas Turbine Maintenance Procedure, MIL-STD-1310 (Shipboard Bonding, Grounding standards), and related drawings. The work requires a nonflammable closure to maintain fire zone integrity per COMNAVSEASYSCOM guidance.
