This is a WebAIM Short Form Task Group Instruction (TGI) for maintenance and preservation work on USS HOWARD (DDG-83). The document specifies preservation work on a flush cover plate and foundation of an Indicator Stabilization Data (ISD) system located in 02 Level Weather, Frames 394-398, at the ship's centerline.
The scope includes removal and reinstallation of one flush cover plate (13-1/2 inches x 16-1/2 inches steel) with new gasket and screw, along with surface preservation of 21 square feet of ISD foundation (outside and inside surfaces) and 3 square feet of deck plating interior surface, all constructed of steel. Contractor work is scheduled to commence November 30, 2026, and conclude March 1, 2027. The work requires compliance with preservation standard 009-032 per Reference No. 1 (NSI FY-27 NAVSEA Standard Items). Government Furnished Material will be provided by SRF-JRMC, including 20 self-locking flat head hex socket screws (ASTM F468, Alloy 500 Mod, 1/4"-20UNC-2A x 1") and 1 square yard of solid rubber sheet. SRF-JRMC will also provide ancillary services including crane and rigging, electrical utility, water/steam/compressed air supply, safety inspections, gas-free inspections, and QA inspection for work requiring certification. Related work for ISD bonding surfaces is covered under separate TGI No. 38JC349201R01.
