Yeah, of course they do. Rigs move around all the time, if they didn't it would mean building a brand new rig for every location. Only idiots would suggest "The "mobility" of oil rigs is largely a myth."
Also, when a production platform is put in place they don't just drill from one reservoir. They can drill from multiple locations at the same time using multiple drill heads. The drill heads are multi-directional.
As you have a far greater degree of understanding in structural construction, correct me if I am wrong here.
1. Oil rigs be they floating platforms or fixed are non the less structures or buildings.
2. A moveable/floating rig is largely constructed on land, be it constructed in pieces and then the large components assembled in the water it is still by in large assembled either on shore or near shore and then later on moved.
3. The costs, logistics, dangers, and ease of constructing near or on land are far better than building a fixed rig hundreds of miles out.
4. The further away from land you set up a rig the more it requires in both logistics support, structural engineering, and safety.
Safety because you are drilling deeper with a longer connection between the rig and ocean floor.
5. It costs more to drill further out because ships need to travel farther out to retrieve the oil of the rig.
Plus added logistics costs for support, IE it costs more to send the guys Toilet Paper and Food.
6. The danger is increased for the workers because it takes longer or may even become impossible to quickly respond to an accident or injury due to distance.
IE a Rig 150 miles of shore will be out of range for most Medi Vac helicopters. And, at best would require people who do nothing other than sit around waiting to put an injured rough neck on the whirly bird.
Am I mistaken on any of these?
