What is this??

To be honest: i have no idea. I know what it is, but not how it is called.
Her name is Innovation and that is very true. It is what the Americans call a liftboat. Basically it is a ship, she has rudders, thrusters and bowthrusters, but also 4 jack-up legs. It is a very sophisticated construction vessel. As soon as she is on location, she stops, lowers her leg until the seafloor is touched and then lifts her own vessel out of the water. By doing so, she can work with her crane undisturbed by wind and waves. Pretty smart.
