This is a detailed technical drawing package for access ladders and platforms for the T-AO 187 Class (198 Series) Fleet Oiler vessel, specifically for accommodation area zones D-4, D-5, D-6, and A-1 through A-7. The drawings, created by Avondale for the Department of the Navy Naval Sea Systems Command, include specifications for inclined ladders, vertical ladders, clips, handrails, and safety features.

The package contains comprehensive fabrication and installation details, including parts lists, material specifications, and assembly instructions for various ladder types and their components. Key features include climber's safety rails, glass reinforced plastic handrails, and wash light access platforms. The drawings specify exact dimensions, angles, materials (primarily steel with ASTM A-36 specifications), and assembly requirements. The document includes pallet code summaries for tracking materials through different assembly stages and detailed tabulations for both inclined and vertical ladders. Multiple key plans show ladder placements across different vessel levels (01 through 08), with specific attention to safety requirements such as minimum headroom clearances and anti-trip provisions.
