Officials say an oil drilling rig on its way to a scrap yard has overturned in Louisiana.
No injuries have been reported, and rig is unrelated to the earlier oil spill in the Gulf of Mexico.
The rig, which was reportedly strapped to a barge, can carry about 20,000 gallons of diesel fuel, but Coast Guard officials did not know how much fuel was on board. Coast Guard investigators say no fuel leaks have been found.
About 500 feet of boom has been set up around the rig to contain any fuel that might leak as a precaution.
