Lights on boat began to flicker before incident, suggesting some sort of power failure. Steering a full size car without power steering is possible, but spoiler, steering a huge container ship ain’t.

Someone commented that exhaust increased noticably as well, possibly because pilot put ship in reverse after losing power (with prop walk veering the ship into the support).

All just people talking on the Internet at present, but “asleep at the wheel” isn’t necessarily what happened.
