A nearly 19,000 ton offshore oil rig broke free during towing in a severe storm early Monday morning, sending it aground on the Western Isles in Scotland.
The Transocean Winner is carrying 300 tons of diesel fuel. During an overnight towing operation, the rig came loose from a tugboat in strong winds and went aground on a beach in Dalmore, reported the BBC. There were no injuries reported and no personnel aboard.

Britain's Maritime and Coastguard Agency is monitoring the possibility of a spill and shut down public access to the beach.
"This morning the tow line between a tug and the Transocean Winner oil rig snapped in heavy weather, resulting in the rig going aground at Dalmore on the west side of Lewis," Western Isles SNP MSP Alasdair Allan told the BBC.
"I am grateful to hear that there have been no injuries reported after this incident but it does leave us with a significant environmental threat to deal with."
