Large concrete structures called Dolphins have been placed around piers that support bridges by deflecting ships that come too close to those bridges. Barzin Mobasher, a structural engineering professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, and other experts comment on the extent to which these structures may or may not be adequate defenses for bridges like the Key Bridge in Baltimore recently destroyed by a large freight ship. Mobasher says Dolphins likely would not have prevented much of the damage, but could have given people enough time to react and possibly prevented the six deaths resulting from the incident.
