Top 7 Largest Crane Vessels

I’m now living in Madeira Island, Portugal, and at the beginning of this week (Monday, January 10th) we all woke up with the beautiful view, south of the Funchal coast and close to the cruise port, of the Saipem 7000, the second biggest crane vessel in the world.

    Some corrections:
    -Saipem 7000: owned by Saipem Italy (not Heerema Marine Contractors).
    -Borealis: correct owner is Acergy, but the picture shows the new build vessel Aegir of Heerema Marine Contractors.
    -Aegir: new build vessel for Heerema Marine Contractors will have a 4000 Tons mast crane.
    You should add the following:
    -Sapura 3000
    -Oleg Strashnov
    -Stanislav Yudin

      Sorry for taking so long in posting your comments.
      Thanks for the information. I already actualized the information about Saipem owner.
      Regarding Borealis, it is very difficult to find pictures of it, but I change the one I originally posted with a new one. I’ll appreciate your feedback on it.
      The other crane vessels you mentioned, are largest than the ones I posted?
