Ultradeepwater drilling units

Petrowiki 

As offshore activities have moved into progressively deeper waters, new types of drilling units have been needed to deal with the conditions found in these locations. Ultradeepwater drilling units are are the technological forerunners and pioneers in the offshore drilling business. Table 1 gives some characteristics of these units, most of them drillships of extraordinary size, but some are semis as listed inTable 2. All were built in the late 1990s and early 2000s. Most have some degree of dual-rig activity (i.e., they have two drilling units on one hull). The Transocean Enterprise Class drillships(Figure 1), for example, have the capability to run two riser and two blowout preventer (BOP) systems with one system drilling and the other completing a well on a subsea template.
