WebAIM Short Form Task Group Instruction for USS SHOUP (DDG-86) Corrosion Pit Repair
This document is a Task Group Instruction (TGI) that provides detailed repair specifications for the USS SHOUP (DDG-86). The instruction authorizes repair work on a corrosion pit located on Oil Tight Longitudinal Girder No. 4(S) in compartment 5-300-01-E, between Frames 300 and 308 on the starboard side. The base material is high-strength steel (MIL-S-22698, Grade DH-36), weighing 20.4 pounds. The work is classified as a Field Order (F/O) and is prepared under Project KC3 with TGI No. 38KC3123CH, issued July 29, 2026. Prepared by Tsubasa Kosuge (Code 231A) and approved by Yuuji Nakamura (Code 231A), with zone manager Takehide Yaginuma overseeing execution.
The repair procedure requires pumping out, cleaning, and drying the bilge area in the Air Conditioning Machinery and Pump Room (5-300-01-E) and Fuel Tank Group-3 (5-300-1-F) to remove oil, debris, and foreign matter. Weld repair of the corrosion pit must comply with NAVSEA Standard Items (NSI FY-27) requirements, specifically sections 009-012 and 009-032, with reference to Drawing 100-7060403. SRF-JRMC will provide supporting services including crane and rigging, electrical and utility services (air, water, steam), safety inspections, gas-free inspections, and QA inspection for "G" symbol work. The instruction clears DFS DDG-86-1000-2026 in its entirety and cross-references related work covered under separate TGIs including dewatering of fuel tanks and space opening/closing procedures.
