Purpose
Bulkheads in a ship serve several purposes:
- increase the structural rigidity of the vessel,
- divide functional areas into rooms and
- create watertight compartments that can contain water in the case of a hull breach or other leak.
- some bulkheads and decks are fire-resistance rated to achieve compartmentalisation, a passive fire protection measure; see firewall (construction).
On an aircraft, bulkheads divide the cabin into multiple areas. On passenger aircraft a common application is for physically dividing cabins used for different classes of service (e.g. economy and business.) On combination cargo/ passenger, or "combi" aircraft, bulkhead walls are inserted to divide areas intended for passenger seating and cargo storage.

Famous quotes containing the word purpose:
“Your good mother tells me you are feeling very badly in your new situation. Allow me to assure you it is a perfect certainty that you will, very soon, feel better—quite happy—if you only stick to the resolution you have taken to procure a military education. I am older than you, have felt badly myself, and know, what I tell you is true. Adhere to your purpose and you will soon feel as well as you ever did.”
—Abraham Lincoln (1809–1865)
“Art for art’s sake, with no purpose, for any purpose perverts art. But art achieves a purpose which is not its own.”
—Benjamin Constant (1767–1834)
“But this fully answered John’s purpose toward Betty, for as she did not understand, she highly admired him; and he concluded by again repeating that learning was a fine thing for a man but ‘twas both useless and blameworthy for a woman either to write or read.”
—Sarah Fielding (1710–1768)
