Ship lights go out ... the lights come back on and the ship maneuvers to ram the bridge. Not an accident in my initial assessment.

If the ship had simply continued on its course after the lights first go out, then it would have missed the bridge pier. Not likely to be enough current to affect a ship of that mass that quickly if it loses power? Hard to imagine why it would turn like that without some input, intended consequence or not.

Lose power, even for a second, means losing steering, loss of steering means the rudder flops where it wants to go, once that happens and regaining power would take some time to correct. Then it loses power again - and plows into a poorly designed bridge that collapses.
