The Key Bridge in Baltimore stood for more than half a century until it collapsed when a massive ship it was never designed to withstand collided with it. Ship collision design provisions, established in 1991, well after the bridge was built, suggest that the chance of collision was extremely low, estimated to be around 1/100,000. This risk assessment, which ultimately proved to be overly optimistic, likely contributed to a false sense of security about the bridge’s vulnerability and may have impeded proactive measures to reinforce the structure.
National ship collision provisions have been mostly unchanged since they were published about 35 years old. The guidelines were derived from 1970s experiments focused on protecting the reactors of nuclear-powered ships from collision by other ships. The studies utilized 1:10 scale models and were geared towards ship-to-ship impacts rather than ship-to-bridge collisions. In addition to these substantial limitations, the provisions also failed to consider the scale and impact force generated by modern, significantly larger freighters that are now in operation. Although the Key Bridge was not constructed in accordance with these later-established provisions, its collapse under conditions deemed extremely unlikely by these standards underscores the pressing need for a comprehensive reassessment and possible revision of these guidelines. This is urgently needed to support the extensive, ongoing national efforts dedicated to evaluating and mitigating the risks of vessel collisions with existing bridge infrastructure.
The objective is this virtual Symposium on August 7, 2024, from 9:00 AM to 3:00 PM eastern time is to highlight the current state of protection of piers / towers of long span bridges in navigational waters from large ship impacts and identify current needs and gaps through an interactive virtual workshop of researchers and practicing engineers.
The symposium will be free to the public and will be delivered through Zoom Webinar. While a detailed agenda will be announced a week prior to the workshop, a tentative list of presenters / speakers is outlined below.
