BD15-95-555-001 CO2 FIRE SUPPRESION SYSTEM.pdf

This is a technical drawing and bill of materials for a CO2 Fire Suppression System designed for the U.S. Army Barge Derrick located at Fort Leonard Wood, St. Louis, MO. The drawing document number is BD15-95-555-001 and is issued by the U.S. Army Aviation and Troop Command.

The system encompasses multiple components including high-pressure CO2 piping, cylinders, valves, manifolds, and related equipment configured for fire suppression across various compartments of the barge. Key technical specifications include: pressurized CO2 delivery systems with cylinder bracketing details, valve assemblies rated for high-pressure operation, nozzle calculations for proper agent distribution, and actuation mechanisms for engine room systems. The bill of materials lists over 25 line items with part numbers, specifications, and materials. The drawings depict detailed isometric views of the manifold assembly, cylinder weighing devices, and system layout within the vessel's hold plan, showing equipment room placement, fuel oil and water storage areas, and ballast configurations. The system design incorporates safety requirements including discharge concentration parameters, temperature operating ranges, electrical contact availability on pressure-operated switches, and clean cut and full thread specifications for piping installations. This appears to be a design or procurement specification document rather than a solicitation for contract services.
