On March 26, 2024, the container ship Dali collided with the Francis Scott Key Bridge in Baltimore, Maryland, causing a catastrophic collapse. This incident resulted in the tragic loss of six lives and significant disruption to the Port of Baltimore’s operations. The Dali, a massive 984-foot-long vessel, experienced a power failure that led to the collision, sparking investigations and raising questions about maritime safety.
The Dali is a Singapore-flagged cargo vessel, built by Hyundai Heavy Industries in South Korea and launched in late 2014. At the time of the accident, it was chartered by Danish shipping giant Maersk for a planned journey from Baltimore to Sri Lanka. The ship’s impressive size and capacity make it a formidable presence on the seas, capable of carrying up to 10,000 standard shipping containers.

The Collision and Its Immediate Aftermath
In the early hours of March 26, 2024, the Dali departed from the Seagirt Marine Terminal in Baltimore Harbor. At approximately 1:25 a.m. EDT, the ship experienced a critical power failure that caused it to lose steering control. The crew quickly issued a mayday call, alerting authorities to the impending danger. This swift action allowed officials to halt traffic on the bridge, potentially saving numerous lives.
Despite these efforts, the Dali struck the southwest pier of the Francis Scott Key Bridge at 1:28:45 a.m., traveling at a speed of approximately 8 knots (9.2 mph). The impact was catastrophic, causing the bridge to collapse within seconds. The ship’s bow became entangled with the fallen bridge structure, trapping it at the accident site.
Casualties and Rescue Efforts
The collapse resulted in the tragic loss of six construction workers who were on the bridge at the time of the incident. These workers, employed by Brawner Builders, were conducting routine maintenance when the disaster struck. Despite immediate rescue efforts, including the deployment of Coast Guard boats and helicopters, only two individuals were rescued from the frigid waters of the Patapsco River.
Investigation and Findings
The National Transportation Safety Board (NTSB) and the Federal Bureau of Investigation (FBI) launched immediate investigations into the incident. Preliminary findings have revealed a series of events leading up to the collision:
- Electrical Issues: The Dali experienced two power blackouts while docked at the Seagirt Marine Terminal, approximately 10 hours before the collision.
- Engine Problems: As the ship departed, it suffered another power loss, causing the main engine to shut down and leaving the crew unable to regain propulsion.
- Mayday Call: The ship’s pilots issued a distress call minutes before impact, allowing authorities to stop bridge traffic but not in time to evacuate the construction crew.
The NTSB’s preliminary report, released on May 14, 2024, provided additional details about the ship’s electrical problems:
- A crewmember inadvertently closed an inline engine exhaust damper during maintenance on March 25, leading to a “blackout.”
- Electrical breakers that fed most of the vessel’s equipment and lighting unexpectedly tripped about three minutes before the collision.
- The emergency generator started shortly after the power loss, but the crew was unable to restore propulsion in time to avoid the collision.
Recovery and Removal Operations
The aftermath of the collision presented significant challenges for recovery and removal operations:
- Bridge Debris: Approximately 4,000 tonnes of debris from the collapsed bridge fell into the Patapsco River.
- Ship Entrapment: The Dali remained trapped at the crash site for nearly eight weeks.
- Controlled Demolition: On May 14, 2024, a controlled demolition was carried out to remove the largest remaining span of the collapsed bridge from the ship’s bow.
- Refloating: On May 20, 2024, the US Army Corps of Engineers successfully refloated the Dali using tugboats under favorable environmental conditions.
The operation to move the Dali to a nearby terminal took approximately 21 hours, marking a crucial step towards reopening the shipping channel and restoring port operations.
Impact on Baltimore and Maritime Trade
The collapse of the Francis Scott Key Bridge has had far-reaching consequences:
- Port Closure: The Port of Baltimore, a crucial hub for maritime trade, was effectively closed due to the blocked shipping channel.
- Economic Loss: The incident resulted in significant economic losses for the region, with estimates suggesting daily losses in the millions of dollars.
- Reconstruction Costs: The state of Maryland has estimated that rebuilding the bridge will cost up to $1.9 billion and take more than four years to complete.
- Legal Action: The city of Baltimore has initiated legal proceedings against the Dali’s owners and managers, alleging gross negligence and recklessness.
Lessons Learned and Future Precautions
The Francis Scott Key Bridge collapse has prompted discussions about maritime safety and infrastructure protection:
- Bridge Design: There’s a renewed focus on designing bridges with enhanced pier protection systems to withstand potential ship collisions.
- Emergency Protocols: The incident highlighted the importance of quick response times and effective communication between ship crews and local authorities.
- Vessel Maintenance: The electrical issues experienced by the Dali underscore the critical need for thorough and regular maintenance of large vessels.
- Traffic Management: The ability to quickly stop bridge traffic likely prevented additional casualties, emphasizing the importance of rapid response systems.
Long-Term Implications
As Baltimore and the maritime industry grapple with the aftermath of this tragedy, several long-term implications have emerged:
- Infrastructure Investment: The incident has sparked calls for increased investment in aging infrastructure across the United States.
- Maritime Safety Regulations: There may be a push for stricter regulations regarding ship maintenance, crew training, and emergency procedures.
- Economic Recovery: The region faces challenges in recovering from the economic impact of the port’s temporary closure and the loss of a major transportation artery.
- Environmental Concerns: The sunken debris and potential for fuel leaks from the ship have raised environmental concerns that will require ongoing monitoring and mitigation efforts.
The Dali incident serves as a stark reminder of the vulnerabilities in our transportation infrastructure and the critical importance of safety measures in maritime operations. As investigations continue and recovery efforts progress, the lessons learned from this tragedy will likely influence maritime safety protocols and infrastructure design for years to come.
