VIDEO from Medialink and Royal Dutch Shell plc: Shell Perdido Spar Reaches the Gulf of Mexico

    World's deepest marine oil and gas development moved to its final
    destination and positioned to the seafloor

    NEW YORK, Aug. 18 /CNW/ -- The Shell-operated Perdido Regional
Development Spar has arrived in the ultra deepwaters of the Gulf of Mexico and
is currently being secured to the sea floor in about 8,000 feet of water. Once
completed, the Perdido spar will be nearly as tall as the Eiffel Tower and
weigh as much as 10,000 cars. Perdido will be the deepest oil development in
the world, the deepest drilling and production platform in the world and have
the deepest subsea well in the world.

    It will be moored by nine chain and polyester rope mooring lines, to an
area of the sea bed the size of downtown Houston. On the sea floor, 22 wells
will be linked to the Perdido spar above. Oil and gas will be pumped to the
surface against the extreme pressure of the deepwater by 1,500 horse-power
electric pumps.
    The Perdido spar was towed 160 nautical miles in just less than two days
to its final work site, an area called Alaminos Canyon Block 857 in the Gulf
of Mexico.
    Positioning the spar into place required carefully-orchestrated
maneuvers. The big spar - 550 feet long and 118 feet in diameter - arrived
floating on its side.  The task was to upend it, rotating it from a horizontal
to a vertical floating position. It took dozens of people from deepwater
construction vessel "Balder" working non-stop for nearly 24 hours.
    Perdido will be a fully functional oil and gas platform with a drilling
rig and direct vertical access wells, full oil and gas processing and remote
subsea wells. The facility is designed to produce 100,000 barrels of oil per
day and 200 million standard cubic feet of gas.
    The Perdido Spar will bring in production from three fields: Great White,
Silvertip and Tobago. These fields are located in 10 Outer Continental Shelf
blocks in Alaminos Canyon, approximately 200 miles south of Freeport, Texas.
This development will provide the first Gulf of Mexico commercial production
from a Paleogene reservoir. All three fields have been granted production
units from the Minerals Management Service and the accumulations are
completely in US waters, some eight miles north of Mexico international
borders. The production from these fields will be transported via new and
existing pipelines to US refineries. First production from Perdido is expected
around the turn of the decade.
    The Perdido Spar will provide living quarters for 150 industry personnel.
The helicopter landing deck will also set new industry records, accommodating
two long-range Sikorsky S92 helicopters simultaneously, each holding up to 24
passengers and crew.
    The construction of the spar was completed in Pori, Finland and travelled
on May 27 2008, 8,200 miles for 23 days to Kiewit Offshore Services
fabrication yard in Ingleside, Texas USA, before being moved to its final
destination in the Gulf of Mexico, on 8 August 2008.
    The spar, is 39 meters (118 feet) in diameter and 170 meters (555 feet)
tall, and weighs approximately 22,000 short tons. The construction of the spar
began in November 2006 to safely complete without any lost time injuries,
requiring more than two million man hours.
    Shell has a proven track record for delivery of these types of systems,
and the Perdido project is part of Shell's continuing commitment to achieving
technically challenging exploration 'firsts' in the search for precious energy
    Shell, the 35% shareholder of the Perdido Regional Development Spar, is
operator on behalf of partners BP (27.5%) and Chevron (37.5%). Perdido is
scheduled to begin production towards the end of the decade.
