I've welded on a few of those.
Between me, my wife, and my two kids automobiles, I've helped keep a few of those in business!:banghead haha
Cray , if its like most it has 8 diesel Electric generators. The engines are about the same size as train engines. It's takes a lot of power to run one. Not sure if it has 8 or 10 thrusters on it. They have a DP system that will maintain a 4 inch position while drilling. The Semi I'm on now got a good test in April. A squall line popped up with 110 knt winds. With all 8 thrusters at 100 percent we only moved 75 ft off location. Got a t-shirt on that for the memories I guess.
Hard to imagine they can stay that close to position. Pretty neat.
