Why do you say that?
This structure was hit head on by a laden container ship. Container ships weigh between 50,000 and 200,000 tons depending on size and cargo. There is not a structure capable of being created by man which could sustain that amount of force, head on, and retain its structural integrity.
Buncha armchair idiots think they know more about bridge construction than civil engineers. Gods, this place is just more and more like Reddit by the minute.
Kinda crazy how those same construction and civil engineers are going to be investigating if the normal means of protection for this very foreseeable event was done correctly, because we design things to avoid these head on collisions:

Also, not for nothing but even if they find out the dolphins in place were sufficient based on prior standards...this event will likely update the standards, same as the sun bridge in the 80s. Regulations and best practices are written in blood.
People always forget that deflection exists. I don't know why that guy is hung up on stopping the ship instead of just nudging it forcefully. If we can figure out a way to deflect explosions and sabot rounds, we can deflect a ship.
Yeah also just the basic concept of sacrificial parts and things designed to wear. The derailleur hanger on your bike, crumple zones in cars, plastic gears in your KitchenAid mixer - lots of engineering practices are designed around shunting failure to a particular piece or in a particular way, to avoid otherwise catastrophic or very expensive damage.
Oh my god! No way! They’re going to investigate and learn from a rare event! That’s shocking!
We study things all the time. Your extrapolation that an investigation means something was preventable is evidence that your higher brain function has been damaged.
You: "There is not a structure capable of being created by man which could sustain that amount of force, head on, and retain its structural integrity.
Actual engineers in the linked article: literally describe how to build secondary structures to deal with giant ships and prevent head on collisions on bridges.
I know you stopped responding but I'm piling on because I'm apparently in an impish mood:

It takes a pretty special kind of small mindedness to think that this accident will be uninteresting to engineers because container ships are simply too heavy to consider building against.
The amount of force needed to deflect a large object is much smaller than to stop it. In fact, if done over a large enough distance, a tiny amount of force is sufficient.
Need an example? Imagine your big brother is skating down a slope. Could you block him, head on? Probably not. But what if your sister, who was skating next to him, were to slightly steer him out of the way so that he doesn’t hit you?
As an alternative, you can also slow him down over a long distance, requiring the same(?) force but applied in a smaller amount, longer.
Because of a contradictory ass like yourself.
