production platform Independence Hub set world record
[July 20] HOUSTON, US--Located in 8,000 feet of water on Mississippi
Canyon block 920, approximately 123 miles southeast of Biloxi, Miss.,
the Independence Hub is the deepest production platform ever installed
and also is the world’s largest offshore natural gas processing
Independence Project The Independence Project in the ultra-deepwater
of the Eastern Gulf of Mexico is a world-record breaking, multi-billion
dollar project that will deliver much needed natural gas to the
U.S. market beginning in 2007.
The Independence Hub is a 105-foot, deep-draft, semi-submersible
platform with a two-level production deck.
The natural gas processed through the Hub when operating
at full capacity represents an increase of more than 10 percent
in supplies from the Gulf of Mexico.
“We are proud to be associated with this groundbreaking
project and all of the individuals whose contributions have set
new standards in offshore engineering and technical achievement,”
said Enterprise President and CEO Dr. Ralph S. Cunningham. “We’re
confident that Independence will serve as the blueprint for future
deepwater development and a model of strong teamwork.”
The Independence Trail pipeline, 100-percent
owned and operated by Enterprise, connects the Hub platform to onshore
markets via an interconnect with the Tennessee Gas Pipeline at Enterprise’s
West Delta block 68 shallow-water manifold platform. The pipeline
is approximately 134 miles long, 24 inches in diameter and has the
capacity to transport up to 1 Bcf/d.
The Independence project set numerous world
records during its construction and installation, which include:
* The world’s deepest platform in approximately 8,000
feet of water
* The world’s deepest subsea production tree in 9,000
feet of water at the Cheyenne field
* The world’s deepest steel catenary riser (SCR) installation
* The world’s deepest export pipeline and SCR, originating
in approximately 8,000 feet of water
The first production from the record-setting
Independence Hub project has been achieved on schedule and within
Atwater Valley Producers Group, consisting of Anadarko Petroleum
Corporation (NYSE:APC), Devon Energy Corporation (NYSE:DVN), Eni
(NYSE:E) and Hydro (NYSE:NHY), along with the owners of the Independence
Hub, Enterprise Products Partners L.P. (NYSE:EPD) and Helix Energy
Solutions Group, Inc. (NYSE:HLX).
The platform is operated by Anadarko and
owned 80 percent by Enterprise and 20 percent by Helix. Anadarko
has reserved approximately 61 percent of the capacity on the Hub,
Eni approximately 20 percent, Hydro 12.5 percent and Devon 6.5 percent.
Natural gas production through the Hub began on July 19, 2007, from
the first of 15 subsea wells located in 10 anchor fields. The producers
expect to ramp up production toward the Hub’s capacity of 1 billion
cubic feet of natural gas per day (Bcf/d) by late 2007.
“The Independence project is a remarkable accomplishment
by our industry,” Anadarko Chairman, President and CEO Jim Hackett
said. “It is a true testament to the collaboration of the partners
and the ingenuity of the individuals who worked to deliver these
once unreachable resources to American consumers. Together we achieved
first production on time and within budget from a world-record-setting
facility in an ultra-deep area of the Gulf where previously there
was no infrastructure.”
