At the time the E/R was pumping ballast, pumping on the cargo holds, trying to isolate the fire main. Water was coming in, list was getting worse. The E/R did say they were going to try to get it back on line, maybe they did add oil but the list was steady getting worse.
When the turn was made to take off the list the ship flopped over to the other side and the loose cargo came across the holds and likely wiped out the fire main. I think once that turn was made it was over.
Anyway even with propulsion what was the captain going to do? The ship was going down, he had no idea where the center was, which way would he have gone that would have done them any good?
