A21 - Encl-19_702-D640-02 - Engine Cooling Keel Cooler Arrangement and Details.pdf

This file is a technical engineering drawing showing engine cooling and keel cooler arrangement details for what appears to be a shallow draft dredge vessel. The drawing includes multiple views and specifications: a plan view (7-D), elevation views (5-D and 7-B), sections (3-D), and several detail views (1-D, 1-C, 4-B) showing components like grid coolers, piping arrangements, and shell penetration details. The document appears to be issued by the Wilmington District of the U.S. Army Corps of Engineers and contains material and equipment specifications for the vessel's cooling system, including aluminum deckhouse components and steel grid cooling elements. The drawing provides precise measurements, construction details, and assembly instructions that would be needed by shipyard contractors performing work on the vessel's engine cooling systems.
