Looks like the accommodation was built out of Containers which is what I thought they were until I had a closer look and saw they were part of the ship!
Built at Hoylandsbygd, Norway as the ROSSNES for Jebsens. 5,699 dwt. speed 14 kts. 1983 :- SAINT BRICE. 2000 :- ROSSNES. 2004 :- WILSON ROSS ( Wilson Shipowning AS, Reg Valletta)
Now registered Bridgetown. I caught her back in 1983 as SAINT BRICE berthed on what was the NCB jetty at Immingham, a view taken from the passing ferry with a 50mm lens - quite a small image in the photo
