​​On April 16, 2024, about 0445 local time, the barges MPC 907 and MPC 644 broke free from their moorings at the Marathon Petroleum Company terminal dock at mile 793.8 on the Ohio River, near Evansville, Indiana. The two barges contacted mooring cells about 1,500 feet downstream at the TransMontaigne terminal at mile 794.1. The barges were later recovered with minor damage. There were no injuries, and no pollution was reported. Damage to the TransMontaigne dock structure was estimated to exceed $2.5 million.

​We determined that the probable cause of the breakaway of barges MPC 907 and MPC 644 and their subsequent contact with downstream mooring cells was a failure of their mooring arrangement in high-water conditions due to an undetermined cause, possibly related to debris in the river.​
