How many ways can you say it wrong? They apparently lost control of the steering. Ships that size do not steer with their propellers. People who know these ships say that the cloud of black smoke seen exiting from the engine stacks before the crash was due to the engines being throttled up after reversing. So the propulsion systems must have been working.
I’m not the one whose premise is that because a priir deficiency was supposedly fixed that nothing else could possibly be wrong ever.
The loss of power (not loss of propulsion) resulted in the loss of hydraulics, and thus loss of control of the ship. If they had maintained power after the first outage, they may have had time to recover...but they lost power again. As it is, they were able to slow the ship in Back Emergency, down to 1.5 knots at the time of the collision.
