This document is a design drawing specification sheet for the Dredge Yaquina, a U.S. Army Corps of Engineers project in Portland, Oregon, prepared by Norshipco (Norfolk Shipbuilding & Drydock Corporation) with design agent JJM Inc. of Virginia. The drawing, designated Y-1034-2, provides comprehensive lists and specifications for doors, hatches, scuttles, and manholes for the vessel.

The document includes detailed tabular specifications across eight sheets covering: steel doors (4 items), aluminum doors (16 items with 44 entries), manholes (56 entries), scuttles (12 items), and hatches (10 items). For each component, specifications detail closure descriptions (type, clear opening dimensions, sill height, swing direction), closure locations (deck, compartment, frame location), hardware characteristics, and special remarks including thermal insulation requirements. Steel doors are specified for compartments such as paint/lamp locker and companionway, while aluminum doors serve passages, storerooms, office spaces, and machinery areas throughout the vessel. General notes establish welding standards per A.B.S. and Coast Guard rules, door construction requirements (flush/hollow insulated types), hardware compatibility, frame material specifications, and lock types (ranging from panic-proof mortise cylinders to hinged covers with safety devices). The drawing was issued July 10, 1978, at a scale of "as noted" with Norshipco contract number 1212 and specification item TS-38, 39, 5-59.
