These are engineering design drawings for the U.S. Coast Guard Cimarron (WLK 65502) Secondary Drainage System, specifically depicting a Naval Engineering project for the 2nd District in St. Louis, Missouri. The drawings include general notes, details, and a bill of materials specifying all required materials and components for the drainage system installation.

The document comprises four detailed sheets containing: (1) a comprehensive bill of materials listing 70 items including welded steel construction components, fittings, valves, pipes, flanges, and various hardware with specifications for size, material, and type; (2) a hold plan and related details showing the layout of drainage system components throughout the vessel, including turbid water drains and drain configurations; (3) an inboard profile and deck layout diagram illustrating the secondary drainage system's placement within the vessel across multiple compartments including the galley, mess, engine room, and staterooms; and (4) detailed elevation, plan, and end views of a retention tank with specifications for construction and assembly. General notes specify that the tank must be constructed of 1/8-inch steel with all welded construction, interior surfaces sanded and finished, complete assembly and testing with a 10-minute hold, and provisions for welded lifting lugs on each section.
