About 0549 local time on February 22, 2015, the US-flagged containership St. Louis Express and the Panama-flagged containership Hammersmith Bridge collided while meeting on the Scheldt River, west of Antwerp, Belgium. The St. Louis Express was outbound from Antwerp heading to its next scheduled port of Bremerhaven, Germany, while the Hammersmith Bridge was inbound to Antwerp. The accident resulted in combined vessel damages greater than $500,000. There were no reports of injuries or environmental pollution.

​​The probable cause of the collision between the containerships St. Louis Express and Hammersmith Bridge was the failure of the pilots and bridge teams on both vessels to assess the risk of collision, inadequate bridge resource management on both vessels, and a lack of communication between the pilots. Contributing to the accident was the failure to establish adequate passing room between the vessels ​while meeting near a major bend in a narrow channel
