The drillship's crews set the latest world record at Lloyd's Ridge block 399 on Anadarko's Cheyenne 2 well, breaking their own records set since June 5, 2006, when the drillship latched onto Merganser (AT 37) for Kerr-McGee.
In addition to the following world records, the Deepwater Millennium has constructed another five wells in approximately the same water depths.
The drillship's world-record water-depth completions are as follows:
Field Block Water Depth in Feet (Meters) Cheyenne Lloyd Ridge 399 #2 8,960 (2,731) Vortex Atwater Valley 261 #1 8,344 (2,543) Merganser Atwater Valley 37 #1 7,933 (2,418) Merganser Atwater Valley 37 #3 7,919 (2,415)
The Deepwater Millennium has been one of the industry pioneers in deepwater drilling and completion. This year, the rig became the first drillship to use the LARS (Launch and Recovery System) Subsea Tree Intervention WorkOver Control System in record water depths on the wells mentioned above. In 2000, the drillship became the first rig to operate in 8,000 feet of water in the U.S. Gulf of Mexico.
Constructed at Samsung Heavy Industries shipyard at South Korea, the Deepwater Millennium is a Pathfinder-class drillship capable of working in up to 10,000 feet of water.
