A massive oil rig with over 300 tons of diesel on board has run aground on the coast of Scotland, according to the BBC.  

The rig was being moved with the aid of a tugboat, but got detached during a recent storm, washing ashore on Dalmore Beach on the Isle of Lewis, the largest island in Scotland. 

No one was on board, according to the BBC, but authorities have closed the beach anyway for safety reasons, as crews arrive to salvage the rig, which weighs nearly 19,000 tons. 

The rig came apart around 4:20 a.m. Monday, after a tow line severed in weather that produced winds of up to 70 mph, according to STV News.

The beach is a popular spot for surfers, owing to big waves and its seclusion, on the north side of the United Kingdom. 

It’s unclear where the oil rig was going, though Scotland’s oil rig graveyard might now be its current destination.
