This ship is the Soukai Maru. The ship looked familiar to me and a Japanese friend translated the characters on the bow as sou kai maru. Sou Kai means Big Ocean. I looked up the ship i knew "Yuben Spring" on Sea-web. com and the ship was called Sou Kai Maru for 4 months between 04-08 2007. The ship when i had seen her was a standard 5 hatch bulker but it looks to me she has been altered to carry cement possibly?
She is now called "Oriental Key", ands was built in 1980 as the Yuben Spring at Kasado dockyard. Her imo number is 7916222 grt 22773.
