The Eighth Coast Guard District recently completed Operation Big Tow, a three-month long effort designed as a result of a collision between a cargo vessel and a loaded oil barge on the Mississippi River that spilled more than 282,000 gallons of #6 fuel oil to spill into the river. Operation Big Tow was designed to ensure vessel operators were properly licensed for their respective vessel's size, type and route. An initial investigation into the July 23, 2008 collision that closed nearly 100 miles of river near New Orleans revealed that a crewmember operating the Mel Oliver, an uninspected towing vessel (UTV) pushing the barge was improperly licensed. UTVs are towing vessels 26 ft or longer and must be under the direction of a licensed master.
