5.3.2 Y-1032-16 General Arrangement.pdf

The file is a detailed general arrangement technical drawing for the Dredge Yaquina, a trailing arm suction hopper dredge vessel. The multi-page technical drawing includes comprehensive schematic views such as inboard profile, front view, hold layout, upper deck, boat deck, bridge deck, and house top, providing a complete structural and spatial representation of the vessel. The drawings meticulously detail the ship's various decks, compartments, equipment locations, technical spaces, and mechanical systems, with precise annotations and abbreviations explaining each component and area of the vessel.

The technical drawings correspond to a planned U.S. Army Corps of Engineers shipyard overhaul project (Solicitation Number W9127N25BA012) scheduled for August 2025 through February 2026, with a 60-day drydock period anticipated in December 2025-February 2026. The overhaul will include comprehensive maintenance tasks such as hull coatings, valve replacements, drag wire renewal, propeller and stern tube inspections, equipment repairs, and dock and sea trials. The project is limited to shipyards in California, Oregon, and Washington, and requires contractors to have or obtain a Master Ship and Repair Agreement (MSRA) with the USACE Portland District.
