This picture shows just how rough the North Sea can get.
Pictured is the Safe Caledonia semi-submersible accommodation vessel.
It belongs to Prosafe and was built in 1982.
The Safe Caledonia has 454 beds, nine offices and 67 client workstations.
The vessel was refurbished in 2012/13.
The refurbishment enhanced the vessel’s facilities as an accommodation vessel and also extended the structural life time of the Safe Caledonia with 20 years.
