This is a photo from a project I was involved with.. After 9/11 it was mandated that infrastructure in the metro NY area be hardened.
I.E. cables/supports etc... in a defined blast zone were protected..
Protection of piers and columns....
This is a robust pier protection system.. ironically the largest vessel this system may have to fend off is a 75' charter fishing boat..
Sheet piling, piles driven to refusal, reinforced concrete . and a composite piles and walers..
I doubt this could have prevented the impact
