NTSB Report: Pilot Error in Ohio River Collision During 2023 Flood

The National Transportation Safety Board (NTSB) determined that the pilot of a barge tug failed to respond to strong outflow conditions, leading to a collision on the Ohio River during the 2023 flood. The incident occurred on 28 March 2023 when the tugboat Queen City, towing 11 barges, collided with the Vane Dike at the McAlpine Locks and Dam in Louisville, Kentucky, causing significant damage estimated at $2 million.

The NTSB report revealed that the barge tug’s pilot did not adequately adjust for the strong outflow while attempting to navigate through the Clark Memorial Highway Bridge toward the Portland Channel. The high water and flow conditions at the McAlpine Locks presented challenges, with water levels around 17.5 feet and rising. The pilot’s attempt to steer the tow westward to enter the canal was thwarted by the strong outflow from the dam.

The NTSB report emphasized the risks that high currents pose for vessels navigating inland rivers, especially near dams where high water results in increased current velocities. The report stressed the importance of considering runoff effects and consulting available resources, such as waterway action plans and company policies, when planning passages through challenging conditions to prevent collisions and ensure safe navigation.
