There was no direct relationship between this pipe and the door. The pipe in question, is one Fredrick Scott says was fetched from the tunnel compartment, to help with pumping out the water forward. Below is the abstract.
5600. (
The Attorney-General.) Yes. (
To the Witness.) And, so far as you know, as I understand it, they never were closed?
- No. Why they opened them was they had to go down the last tunnel but one and get a big suction-pipe out, which they used for drawing the water up out of the bilges.
5601. That tunnel is the one before you get to the last watertight door where they went to get a big suction pipe?
- Yes, it takes four men to carry it. I think I saw four men coming through with it. They took it to the stokehold. What they did with it I do not know.
Scott, like Dillion, was ordered to heave up the watertight doors after they had been released by the bridge, after the collision, and after this was done the pipe was brought through. That is the only connection between the doors and the pipe (they just had to be opened to get it through). Hope this helps.
