(CNN) A massive oil rig was blown ashore in Scotland during a severe storm early Monday morning.

The more than 19,000-ton drilling rig, Transocean Winner, was being towed west of Scotland's Isle of Lewis when it was hit by the harsh weather.

In a statement, the UK Maritime and Coastguard Agency (MCA) said it became detached from the tug boat around 4:20am BST and became grounded at Dalmore Beach near Carloway.
