About this file
This document is a Task Group Instruction (TGI) for ship repair work on the USS Yorktown (YR-85), prepared by the U.S. Navy. The work scope involves repair and replacement of structural members and studs across multiple deck levels of the vessel, specifically addressing corrosion holes and general corrosion damage identified in a condition report dated August 14, 2024.
The primary work activities include: removal and installation of stack studs for cableways and electrical equipment on the main deck through 03-level weather decks (frames 13-100, port and starboard); fabrication and installation of new structural members including stiffeners and deck plates with specific material specifications (medium steel per MIL-S-22698); weld repair of gouges and corrosion holes on bulkhead plating and lateral stiffeners with air hose testing (zero allowable leakage); drilling and countersinking of holes per specified diameters; and painting of new and disturbed surfaces. The work locations span multiple compartments and rooms across the ship. Government-furnished material will be provided by SRF-JRMC, along with crane services, utilities (electrical, low-pressure air, water, steam), safety and gas-free inspections, QA inspection, and on-site engineering support. Materials required include stack studs (175 total units), adhesives, insulation blocks, tape, metal plates, and associated fasteners. Work is referenced to NAVSEA standards and MIL-STD specifications for welding and structural requirements. The TGI includes detailed engineering instructions, material lists, and location sketches across multiple enclosures.
