A large fire broke out on an MSC cruise ship docked in Greece on Friday.

The fire started on a fiberglass lifeboat on the MSC Lirica before 3:42 p.m. local time and sent large plumes of smoke billowing into the sky, according to MSC Cruises.

The ship is docked at the port of Corfu for the winter with 51 crew aboard, but no passengers. There were no injuries, according to the cruise line.
