A bulkhead on a ship refers specifically to the walls that divide the interior spaces of the vessel. These vertical partitions serve multiple important functions, including providing structural support to the ship's design, creating watertight compartments to enhance safety in the event of flooding, and helping to minimize the spread of fire and smoke by compartmentalizing different areas within the ship.

Understanding the role of bulkheads is crucial for comprehending maritime design and safety protocols. Other components of a ship, such as the outer hull, deck, and interior compartments, serve different purposes and are not defined as bulkheads. The outer hull is the ship's protective exterior; the deck refers to the horizontal surfaces where crew members may walk or equipment can be situated; and the interior compartments pertain to the various enclosed spaces that can house people, cargo, or machinery, which may be sectioned off by bulkheads. This distinction highlights the specific function that bulkheads play within the overall architecture of a ship.
