The Chinese have the info locked down pretty tight it seems. Word will eventually get out though.
I can't fathom the Chinese not taking a stab at us in the near term... if they haven't already. After drilling the three blocks, I'm sure both parties will be able to put some calculated numbers together.
Red, the DP does not have two derricks. I've read that is has been upgraded to a "dual drilling system", but I do not understand what exactly that means.
Red, my understanding, which may be way wrong, is they use one derick to position the new pipe on the rotary table while the next section is being assembled on the other derick. Essentially they trade back and forth adding to the drill string, with two dericks they are twice as fast.
I picked this up from an article about the deepwater pathfinder someone had posted last month
