Well it looks amazing but as a layman I'm bewildered about what all the bits are for. I believe it is anchored above oil/gas wells and connections from those go up into the turret at the front? Do tankers come and offload from it periodically? Will it spend it's life above a well until it is exhausted and then go on to another, or does it tour around, somehow? What is the tall derrick like structure for- surely not drilling? What are the yellow cylindrical towers for, maybe just cranes, but why so tall? Does it have to pump stuff down into the wells as well as receiving product from them?
