摘要：	The mv. Robert Cenac, a 60-foot-long, 1,400 hp. towing vessel in Al Cenac Towing's fleet, was pushing a 150-foot-long crane barge called the Mr. Dawg eastbound on the Gulf In-tracoastal Waterway (GIWW) in the early-morning hours of March 6, 2022, when the head of the crane boom hit the outermost stringer of the Houma Twin Span Bridge, causing $1.5 million to $2 million in damage and impacting vehicular traffic over the busy bridge for 10 days.According to the National Transportation Safety Board (NTSB), an employee with Sealevel Construction, which owned the Mr. Dawg, contacted an Al Cenac Towing sales representative around 8 p.m. on March 5 to charter a vessel to transport the Mr. Dawg and another deck barge from the Houma area to the Louisiana Offshore Oil Platform (LOOP) facility in Clovellv, La. During that phone call, the Sea-level employee reportedly told the Al Cenac Towing representative that the crane boom had been lowered "below the top of the fully raised barge spuds," which were said to be 50 feet high, according to the NTSB report.
