A tug boat crew got off the vessel safely before it sank near LaPlace Thursday.
Friday a diver went down forty feet to cap off its fuel vents.
The boat was carrying 4,000 gallons of diesel fuel and 100 gallons of lube oil.
The diver will have to go down again to put straps around the boat.
A crane will use the straps to pull it out of the water.
Rob Olmstead with the U.S. Coast Guard said, “The river can be very dangerous so it’s very good that no one was injured in this. We’re extremely happy about the fact that they were able to get off without entering the river.”
Olmstead says the boat was taking on water at the stern before it went under.
