This is a technical drawing/engineering diagram showing shell plating and framing details for a shallow draft dredge vessel. The drawing includes multiple views including elevation, plan, and cross-section details of the vessel's bottom structure, side plating, and framing elements. Specific components shown include bottom plating measurements, cylinder room details, sea chest specifications, trunnion penetrations, and various structural elements with precise measurements and materials called out. The drawing was created by the Wilmington District Corps of Engineers and appears to be part of a larger set of technical specifications for shipyard repair services for the Dredge Murden vessel. Critical details include plating thicknesses (ranging from 3/8" to 7/16"), structural frame spacing, and specialized components like bilge radius seams and hull trunnion penetrations.
