About this file
This is a WebAIM Short Form Task Group Instruction (TGI) for the USS Rafael Peralta (DDG-115), a naval destroyer. The document outlines preservation and replacement work for a ventilation hood system at Frame 240, 01 Level Weather on the vessel, with a work period from August 3, 2026 to September 1, 2026.
The scope encompasses removal and replacement of two bolted access covers and two punched weather screens of the vent hood located at Frame 240 (Port and Starboard), plus preservation treatment of approximately 56 square feet of interior vent hood surface including transverse bulkhead plating. The work references Supply Systems 2-271-1 and 3-252-2 and requires compliance with preservation requirements per Reference No. One (NSI FY-26 NAVSEA Standard Items), specifically accomplishing 009-032 requirements including Table 5, Line 23 for the access covers and weather screens, and Table 2, Line 1 for the interior surfaces. Materials to be furnished by contractor include stainless steel sheet metal (1 sheet, 4'x8', 0.125" thickness), stainless steel and nylon fasteners (screws, washers), and rubber sheeting. SRF-JRMC will provide government-furnished materials and service work including crane services, electrical utilities, water/steam/air supply, safety and gas-free inspections, and QA inspection. Related work for disconnection/reconnection of shower power cable and exterior surface preservation is covered under separate TGIs. The instruction was prepared by S. Yamaoka (Code 231B) and approved by R. Takagi (Code 231B) on October 31, 2025.
