Marine Accident Brief: Contact of Mary Lucy Lane Tow with Markland Locks and Workboat Gibson, December 18, 2018

About 1555 on December 18, 2018, the towing vessel Mary Lucy Lane, with eight crewmembers on board and pushing a tow of 12 barges, was locking southbound at the Markland Locks & Dam (L&D) at mile 531.5 on the Ohio River, when the tow struck the lock’s wall, then its guard wall. Several barges broke loose and continued forward, one of which collided with the moored US Army Corps of Engineers workboat Gibson. No injuries or pollution resulted from the accident. Damage to the Mary Lucy Lane, the barges, and the dam was estimated at $321,943, and the Corps of Engineers estimated the cost to replace the Gibson at $1.8 million. ​The National Transportation Safety Board determines that the probable cause of the contact of the Mary Lucy Lane tow with the Markland Locks and workboat Gibson was a strong outdraft above the dam caused by the extreme high flow conditions, which overwhelmed the pilot’s ability to control the Mary Lucy Lane tow before locking.
