A tanker carrying 308,000 barrels of crude oil ran aground in Puerto Rico early Thursday but there were no signs of a spill, Coast Guard officials said.
The Coast Guard received a call around 1:15 a.m. that the tanker ran aground about three miles south of Tallaboa, Puerto Rico, said Petty Officer James Judge. It was on its way to Puerto Rico from Cartagena, Colombia.
Marine inspectors are on scene at the 748-foot Margara, a Cayman Islands flagged vessel, to determine if any crude leaked.
The cause of the grounding is under investigation. No injuries were reported.
