[ALIEN] whats the purpose of the spooky chains and water room?

I just saw this a few hours ago, and I dont get why a cargo ship has a spooky chains and water room.

to specify the room I am talking about, when one of the engineers (Im bad with names) goes after the cat, and he gets to this room he looks up at the water and lets it drip all over his face.

The chain hangs from an industrial rail-crane. Its purpose is to help lift heavy objects, when the ship is in full-g. Since the ship is a longhauler, there is probably a lot of heavy equipment to lug around.

This would be epecially important in a water room (which is essentially an internal water-tower) since such a room would be much taller than its width, pretty much a shaft with a water tank in it.
