This image provided by the U.S. Coast Guard shows a pipeline burning after a collision near Bayou Perot 30 miles south of New Orleans, Tuesday March 12, 2012. The pipeline fire that was ignited when the pipe was hit by a tug boat pushing an oil barge burned into the early morning hours Wednesday in a bayou south of New Orleans. There was still liquid petroleum gas in the 19-mile pipeline and authorities were waiting for it to burn out, Coast Guard Petty Officer Alex Washington said.
