June 18 BP Plc (BP.L)(BP.N) is moving ahead
with its plan to increase oil-capture capacity at its gushing
Gulf of Mexico leak to 80,000 barrels a day (3.4 million
gallons/12.7 million litres) by mid-July.
Here are details of BP's efforts, as explained by the
company an the U.S. Coast Guard:
* A containment cap atop failed blowout preventer equipment
at the seabed captures oil from the leak. It channels the oil
through a fixed pipe to Transocean Ltd's (RIG.N) Discoverer
Enterprise drillship at the ocean's surface, one mile (1.6 km)
* The Enterprise can process up to 18,000 barrels a day and
store up to 147,000 barrels.
* A service rig, the Helix Q4000, siphons more oil from a
hose and pipe connected to the blowout preventer.
* Oil must be burned off because the rig has no storage
capacity to keep it onboard. Natural gas is flared as well.
* The Q4000 can take more than 10,000 barrels a day.
MORE CAPACITY COMING
* By July 7, BP intends to hook up a third vessel that will
increase oil-handling capacity to up to 53,000 barrels a day.
* BP will connect a second blowout preventer hose to a
floating pipe connected to the Helix Producer, a rig with
capacity to process up to 25,000 barrels a day.
* The floating-pipe setup allows the vessel to disconnect
quickly from the pipe and move out of the way if a hurricane
MORE HURRICANE PREPAREDNESS
* In the next seven to 10 days, U.S. officials and BP will
decide whether to replace the containment cap with a larger cap
and seal designed to capture all or most of the crude leaking
from the top of the blowout preventer equipment.
* By mid-July, the Toisa Pisces, a well-testing ship
revamped to process up to 25,000 barrels a day, will replace
the Q4000 and be connected to the blowout preventer via a
second floating pipe.
* The Discoverer Enterprise and a second drillship,
Transocean's Discoverer Clear Leader, will each be connected to
the new containment cap via hoses and drill pipes.
* The four vessels will have a combined capacity of up to
80,000 barrels a day and can disconnect quickly to move out of
a hurricane's path.
ANOTHER HURRICANE-READY POSSIBILITY:
* BP is looking into designating one or more Gulf platforms
to collect and process oil and gas from the leak.
* The system could involve fabricating and laying a new
seabed pipeline to channel oil to one or more platforms.
* The pipeline could also possibly channel oil to an
abandoned well to be injected back into a reservoir.
* Platforms are moored to the seabed and built to withstand
storms, while drillships and rigs typically disconnect from
seabed operations and move when a hurricane comes.
THE RELIEF WELLS
* Drilling continues on two relief wells intended to
intercept the well and plug the leak well beneath the seabed.
The first was begun on May 2 and the second on May 16. Both are
expected to be finished in August. Of all the methods BP has
used to try to contain the oil, the relief wells are the only
proven technology expected to plug the leak.
