The Deepwater Nautilus Team has set another world water-depth record for an offshore drilling rig operating in moored configuration at 8,951 feet of water in Lloyd block 399 in the U.S. Gulf of Mexico for Shell. The achievement surpasses the prior world record for a moored rig of 8,717 feet of water set by the Deepwater Nautilus Team last year for Shell in Alaminos Canyon block 857 in the U.S. Gulf of Mexico.

The Deepwater Nautilus Team has been setting world water-depth records for a moored unit since the deepwater semisubmersible went on its first location in 2000 for Shell. The team's previous world records, all of which were achieved in the U.S. Gulf of Mexico, include the following:

Deepwater Nautilus Team
World Moored Water-Depth
Location Year
7,785 feet Alaminos Canyon 557 2000
8,009 feet Alaminos Canyon 857 2002
8,070 feet Alaminos Canyon 813 2002

As a pace-setter for world water-depth records by a moored rig, the Deepwater Nautilus Team brings a strong commitment to excellence and safe operations. Everyone, from the crewmembers to other contractors and Transocean's client, Shell, deserves congratulations for these achievements while continuing to work hard and remain focused on incident-free operations.

The Deepwater Nautilus is one of 13 Transocean fifth-generation mobile offshore drilling rigs that work in the world's deepest water depths. A multi-operation-class rig, the Deepwater Nautilus can operate within a pattern of eight mooring legs. A 9,400-metric-ton deckload accommodates all the equipment, riser, conductor and casing to start a well and work through setting the BOP on the wellhead quickly and efficiently.

In addition to the world water-depth records for a moored rig, the Deepwater Nautilus Team also holds the world record for the deepest subsea completion, set recently at 7,570 feet of water on the Shell-operated Coulomb project C-2 well in the U.S. Gulf of Mexico.
