I saw Saipem 7000 probably on the same day as Paul did, 5th Aug. 2010. What makes this colossus more astonishing is that she is has her own propulsion system so she can travel the world without he need of tugs (albeit not very fast) and is therefore a proper ship in her own right. Most other rigs and platforms have propulsion systems - but only for positioning.
I see the Albatros is due again tomorrow. If you thnk she looks familiar she's one of three ships built for the up-market Royal Viking Line in the early '70s. All were stretched at roughly the same time and as the market developed they were sold on. Two of these fine ships are now owned by Fred Olsen, Black Watch and Boudicca, and the third is the Albatros.
