The very article you linked, from the first of the experts, states, “There was no way to protect the bridge, even if there was a warning system in place. If a ship like this collides on with any bridge it may take it down.”
Each expert after basically says the same thing. Even with extra protections using modern technologies, a head-on collision from a boat of this size and weight would destroy almost any bridge, and there is no practical fender system to effectively deflect a ship of this size. Most suggestions are that a more modern bridge would simply have a wider channel, but a modern bridge with modern fenders and plant of dolphins would not have stopped a head-on collision like this. And a wider channel wouldn’t matter if a boat if this size still ran directly into one of the (wider spaced) direct supports.
Other experts here note radar and sonar protections and lighting, none of which would have mattered here because the problem is the Dali lost power and navigation, which is what caused them to run directly into the bridge pylon. The pylon could have been made out of neon lights: they couldn’t turn. I don’t think you’re taking into account just how massively heavy this ship is.
That says there is no way to stop a head on collision, which is true. Hence why you divert the boat before it hits the bridge structure.
As I have already mentioned and as many of the other professionals in that site point out:
“It is almost impossible to design a bridge pier to withstand this kind of impact. Therefore, we tend to design impact protection measures to prevent it from happening instead.
And
“From the photos I can see what appears to be a solitary dolphin-type structure on each side of the two main piers. If so these look to be inadequate to deflect anything other than small vessels.
And
I do not know the history of this bridge, but it looks like an old bridge that was designed neither for ship impact nor had any ship impact barrier to avoid the problem.
And
”I do not know what the arrangements were for this bridge but major bridges over shipping lanes must have substantial protection for piers or columns. These protections are either in the form of structural protections like ‘sacrificial dolphins’, which are made of steel and embedded in the seabed to stop or divert a ship. They can also be in the form of artificial islands; these are for very large ships and mean the ship will never reach the bridge pier itself. If piers are not protected adequately then they are vulnerable to ship collision. Clearly the protection of the piers in this instance was inadequate.
And
Bridges in shipping lanes are sometimes designed with strong, stout piers, or additional protective structures around the piers to prevent ships from coming into contact with the bridge structure. It doesn’t appear that the Key Bridge had either of these features
