Collision Bulkhead

When you checked the tubes to see if they were okay, water would come in, too much water to permit the rear doors to be shut again, but not under such high pressure that you wouldn't have time and enough to spare to close the fo'ard collision-bulkhead door and make a leisurely retreat in good order. ❋ MacLean, Alistair, 1922-1987 (1963)

We stepped over the eighteen-inch sill, leaving the five men behind, and waited until the door had been latched again before opening the for'ard collision-bulkhead door and stepping over the second sill into the cramped torpedo room. ❋ MacLean, Alistair, 1922-1987 (1963)

Bowen grinned and unlatched the first collision-bulkhead door. ❋ MacLean, Alistair, 1922-1987 (1963)

I left Hansen to secure the remaining latches and started knocking those of the after collision-bulkhead door. ❋ MacLean, Alistair, 1922-1987 (1963)

"Ease off!" shouted the forward collision-bulkhead. ❋ Rudyard Kipling (1900)

Naturally everything in the Dimbula fairly stiffened with pride, and the foremast and the forward collision-bulkhead, who are pushing creatures, begged the Steam to warn the Port of New York of their arrival. ❋ Rudyard Kipling (1900)
