Something like a more thorough tug escort seems more appropriate than trying to design the bridge to withstand the hulk throwing the world trade center at it. There are no shortage of experts in the news saying "ship proofing" the bridge is like trying to build a bridge that the military can't destroy.
Once again from that article we are right back to "Shipping companies don't like to pay for the escort".
The ship was escorted part of the way and then waved them off.
To me the article reads like the tug company is trying to be diplomatic and cover their bases so won't say for sure whether their tugs could have stopped it.
There are a bunch of tugs where if you take two of them their combined pull/engine power is more than the Dali's powerplant and they wouldn't have had to stop it, just nudge it.
