Drawing 512-6233792_ Heating Ventilation and Air Conditioning Diagram.pdf

The document is a detailed Heating, Ventilation, and Air Conditioning (HVAC) diagram for the NOAA Ship Okeanos Explorer, drawing number 512-6233792. The multi-page technical drawing includes comprehensive schematic layouts across different decks (Bridge Deck, Upper Deck, Main Deck, Lower Platform) with intricate system diagrams showing air handling units, ductwork, temperature controls, and ventilation routing. The first page contains general notes providing technical specifications and guidelines for the HVAC system installation, including requirements for equipment placement, airflow, temperature ranges, and system design considerations. Additional pages show profile and side views of the ship's structural layout, with specific detailed sections for various mechanical and environmental system integrations.

The drawing appears to be a critical engineering document for the FY26 drydock repair of the Okeanos Explorer, a NOAA research vessel. The HVAC system diagram provides a comprehensive technical blueprint for the ship's climate control infrastructure, supporting the vessel's operational requirements across multiple deck levels and functional spaces. The detailed schematics would be essential for maintenance, repair, and potential system upgrades during the planned drydock maintenance period.
