Sometimes we think that semi-submersibles drilling vessels are quite big things, but they are nothing compared to the heavy lift vessels, and this one the Saipem 7000 is said to be the second largest in the world. The two cranes combined can lift 14,000 tons, making it possible to lift most platform topsides into position in a single lift. It has a DP3 positioning system using 12 thrusters and has accommodation for over 700 people. It has 12 generators developing a combined 70,000 kW.
