vineseeker2...I recall the article you mention also, I don't believe the DP has 2 derricks however, but it has dual swing arms or something similar. These pieces of equipment allow the work-flow to essentially be twice as fast, because the next drill string is being positions while the first is locked and loaded,

...this is not gospel however!, only what I think I recall reading.
