Perhaps if your questions were more detailed, would be of help.
Are you asking, construction, purpose, measurements, door operation, heights varied etc.

Wrong with what, the bulkheads, the doors, the ship ?
>> And anything you know ?<<
There are members within this Forum who could write a book on any of the above sections.
I am sure you would get a response to a direct question.
I thank all who provide valid information. GORDON
So I have a question about how the Water Tight Bulk Heads work?
I never understood how they would keep the ship afloat but now I think I get it...
The compartments extended above the water line right?
Now if X amount of the compartments flooded the ship would still be buoyant enough to float... The water would rush in until it got to the water line, and then it would stop?
But if more than the max needed to stay afloat were compromised then it would cause the ship to dip down below the water therefore causing a loss in buoyancy and then the water would keep rushing in and spilling over?
That's the general idea. What watertight bulkheads do is to confine flooding to a given area of the ship so that she will either remain afloat or survive long enough for rescue vessels to arrive.
The catch is that if more watertight sections are compromised then what the ship can survive, the sheer mass of the water ingress along with the loss of stability will be enough to send her plummeting to the bottom.
Think of a dam in the river. The barrier has no openings in it through which water may pass save for those doors which can...if need be...closed to stop the spread of flooding. The difference is that the barrier is made of iron or steel instead of concrete.
