WBAL-TV 11 NEWS. ALL RIGHT CARRIE, THANK YOU. WELL, BRIDGE PROTECTIONS THAT COULD PREVENT A CARGO SHIP FROM EVER COLLIDING. THAT WAS ONE OF THE TOPICS THAT JOHNS HOPKINS UNIVERSITY EXPERTS ADDRESSED DURING A MEDIA BRIEFING THIS MORNING. INVESTIGATIVE REPORTER TOLLY TAYLOR JOINS US NOW LIVE IN TOLLY. THESE QUESTIONS WERE FOCUSED ON THE PROTECTION SURROUNDING THE BRIDGE. PIERS. YEAH, RIGHT. WHEN THE DOLLY SLAMMED INTO THE KEY BRIDGE, IT TOOK OUT ONE OF THE BRIDGE PIERS, CAUSING THE TOTAL BRIDGE COLLAPSE. SOME BRIDGES ACROSS THE COUNTRY HAVE FENDERS OR PROTECTIVE BARRIERS SURROUNDING THEIR PEERS TO KEEP BOATS AND SHIPS AWAY. HOPKINS PROFESSOR BENJAMIN SCHAEFER IS A STRUCTURAL ENGINEER, AND HE NOTED THE KEY BRIDGE ONLY HAD VERY MODEST FENDERS FOR ITS PIERS, ONLY STRONG ENOUGH TO REDIRECT A SMALL FISHING BOAT IN HIS ESTIMATION. BUT HE ALSO SAID HE’S NOT SURE THAT ANY MODERN PROTECTIONS WOULD HAVE BEEN ENOUGH TO WITHSTAND A DIRECT HIT FROM A SHIP THE SIZE OF THE DOLLY. COULD WE BUILD A FORT KNOX? UH, YOU KNOW, A NUCLEAR BUNKER IN FRONT OF EVERY BRIDGE? UH, IT’S STRUCTURALLY POSSIBLE, BUT IT’S NOT ECONOMICALLY FEASIBLE. UM, AND SO EVEN IN THE MOST EXTREME, UH, BRIDGE PROTECTION SYSTEMS, UH, THAT WE SEE AT THIS POINT, I REMAIN UNCONVINCED THAT IN A SIMILAR INCIDENT THAT THEY WOULD PERFORM SUCCESSFULLY. SCHAEFER SAYS HE DOESN’T REFER TO WHAT HAPPENED TO THE KEY BRIDGE AS A COLLAPSE, CALLING IT AN INFRASTRUCTURE SYSTEM FAILURE BECAUSE THE BRIDGE WAS DESTROYED. AND HE SAYS WHEN A NEW BRIDGE IS BUILT TO REPLACE THE KEY BRIDGE, MOST OF THE NECESSARY IMPROVEMENTS WON’T BE PHYSICAL. THERE’S THE PHYSICAL THINGS THAT WE SHOULD DO IN THE NEW BRIDGE, BUT IT’S PROBABLY THE SOCIAL THINGS. AND MANY OF THE MARITIME CHANGES THAT WE MIGHT NEED TO MAKE TO MAKE THE WHOLE SYSTEM, UH, WORK SUCCESSFULLY SO WE DON’T HAVE ANOTHER BRIDGE STRIKE. NOW, US TRANSPORTATION SECRETARY PETE BUTTIGIEG SPOKE ABOUT THE SHIP AT A NEWS CONFERENCE THIS AFTERNOON AT THE WHITE HOUSE, COMPARING ITS SIZE TO A SMALL AIRCRAFT CARRIER. HE ALSO SAID THE SHIP’S WEIGHT

Hopkins consultants handle bridge protections, modifications forward

Experts are addressing key questions raised after the Francis Scott Key Bridge was struck by a cargo ship and destroyed.One of the subjects mentioned: bridge protections that would stop a ship from colliding. When the Dali slammed into the Key Bridge, it took out one of many bridge piers, inflicting the collapse.Some bridges throughout the U.S. have fenders, or protecting limitations, surrounding the piers to maintain boats and ships away.Johns Hopkins professor Benjamin Schafer is a structural engineer.

It’s structurally potential, but it surely’s not economically possible. And so, even in probably the most excessive bridge protections that we see, at this level, I stay unconvinced that in an identical incident, that they’d carry out efficiently,” Schafer mentioned.That echoed some extent raised by U.S. transportation secretary Pete Buttigieg on Tuesday.”I have no idea a bridge that has been constructed to resist a direct influence from a vessel this measurement,” he mentioned.Schafer mentioned he does not confer with what occurred to the Key Bridge as a “collapse,” calling it “an infrastructure system failure,” as a result of the bridge was destroyed.When a brand new bridge is constructed to interchange the Key Bridge, he mentioned many of the mandatory enhancements is not going to be bodily.”There’s the bodily issues that we must always do within the new bridge, but it surely’s most likely the social issues and most of the maritime modifications that we would have to make to make the entire system work efficiently, so we do not have one other bridge strike,” Schafer mentioned.Buttigieg in contrast the scale of the Dali to a small plane provider, weighing 200 million kilos.Hopkins consultants additionally addressed the enterprise results of the collapse.

Experts are addressing key questions raised after the Francis Scott Key Bridge was struck by a cargo ship and destroyed.

One of the subjects mentioned: bridge protections that would stop a ship from colliding. When the Dali slammed into the Key Bridge, it took out one of many bridge piers, inflicting the collapse.

Some bridges throughout the U.S. have fenders, or protecting limitations, surrounding the piers to maintain boats and ships away.

Johns Hopkins professor Benjamin Schafer is a structural engineer. He famous that the Key Bridge solely had very modest fenders for its piers — solely sturdy sufficient to redirect a small fishing boat, in his estimation.

He mentioned he is undecided any fashionable protections would have been sufficient to resist a direct hit from a ship the scale of the Dali.

“Could we construct a Fort Knox, a nuclear bunker in entrance of a bridge? It’s structurally potential, but it surely’s not economically possible.

That echoed some extent raised by U.S. transportation secretary Pete Buttigieg on Tuesday.

“I have no idea a bridge that has been constructed to resist a direct influence from a vessel this measurement,” he mentioned.

Schafer mentioned he does not confer with what occurred to the Key Bridge as a “collapse,” calling it “an infrastructure system failure,” as a result of the bridge was destroyed.

When a brand new bridge is constructed to interchange the Key Bridge, he mentioned many of the mandatory enhancements is not going to be bodily.

“There’s the bodily issues that we must always do within the new bridge, but it surely’s most likely the social issues and most of the maritime modifications that we would have to make to make the entire system work efficiently, so we do not have one other bridge strike,” Schafer mentioned.

Buttigieg in contrast the scale of the Dali to a small plane provider, weighing 200 million kilos.

Hopkins consultants additionally addressed the enterprise results of the collapse. One professor mentioned, whereas the port is not the largest nationally, it’s a specialised port, particularly important within the position it performs for the auto trade.

With the port closed, it may influence the provision chain.
