If You search on "FOB 7", I think that You will see the original arrangement of these series of ships.

Very interesting to see this picture: I think that this originally was built in a series of ships named "FOB" with numbers, for Norwegian owners, and thus a sister ship of IMO 8328147, "Cap Blanc", ex "FOB 7", which capsized in 2008. These ships were originally built as general cargo ships, with all cargo on deck. Thus the super-structure/housing on deck was only in front of the solid mast. And I think that "Mamaia 2" did not have a yellow crane as shown on this picture. This kind of ships had quite a challenge with deck cargo in heavy weather. Before these FOB-ships were built, I was on a meeting in Bergen/Norway shown drawings of this new design.
