Moving upriver to Rothesay Dock this afternoon, fully laden with a cargo of refined petroleum products, the Norwegian-flagged tanker NORTHERN OCEAN may be a new name on the Clyde, but in fact she is a well known visitor, having been here many times in the past. Built in China in 1998, and now owned by Donso Bunker Services, she is wearing new hull colours, but much of her main deck is still painted in her former owner's livery. She is a 13,781 tonne vessel, of 134.66 metres overall length, and had arrived in Brodick Bay from Brofjorden in Norway on Tuesday afternoon. Her previous identity? Until the end of December last year, she would have been seen on the Clyde in this guise.
