5.6.6 - Y-2494-3 Hopper Framing.pdf

The file contains detailed engineering drawings for the Hopper Plating & Framing FR 32-53 component of the Dredge Yaquina, specifically focusing on structural details for the vessel's hull and frame sections. The technical drawings, created by NORSHIPCO for the U.S. Army Corps of Engineers, provide comprehensive technical specifications including multiple sectional views, structural details, general notes, and references for welding, materials, and structural construction. The drawings include key plan views showing expanded details of various structural elements, with precise measurements, annotations for tank tops, deck references, and structural connections, adhering to specific engineering standards and material specifications.

The drawings are part of the broader U.S. Army Corps of Engineers' planned overhaul of the Dredge Yaquina, which is scheduled for a shipyard availability from December 2025 through February 2026, with a 60-day drydock period. The technical specifications will be critical for the maintenance and repair work to be performed under the Master Ship and Repair Agreement (MSRA), with the work to be conducted at a contractor's facility in California, Oregon, or Washington, focusing on comprehensive vessel structural and systems renovation.
