To your last comment, ships never just boop. It smothers.
Let’s say 100k tons for a ship, and make it long tons to make it an even 100,000,000kg. This ship was moving roughly 4m/s… Thus the kinetic energy was somewhere around 800 MJ. A stick of dynamite is about 1MJ.
I’m pretty sure 800 sticks of dynamite could’ve fucked that support up pretty good, too, bringing down the bridge deck.
It’s more like either you give up on bridges or give up on ships if you are concerned about the two coexisting and breaking stuff in a low speed collision.
