BP’s Mexican Gulf
Oil Disaster:
Obama’s Katrina?
Raghu
THE horrific
on-going disaster caused by oil spewing out from British Petroleum’s
(BP) well
in the Gulf of Mexico is going from bad to worse, showing little signs
of
abating. It is already by far the biggest oil spill in the US and
rapidly
becoming one of the worst man-made environmental disasters in the US if
not the
world. The oil slick is spreading by the day and threatening new areas.
The
federal government has banned fishing in more than 37 per cent of the
US part
of the Gulf of Mexico, double the area under a fishing ban imposed
mid-May.
BP is responding in
a manner typical of large multinational corporations (MNCs), especially
oil
companies, trying to minimise the damage while spending as little money
as
possible, evading legal liability, and treating the whole episode as
primarily
a public relations issue. BP is once again showing that Big Oil is the
dirtiest
of businesses, in more ways than one.
The US
administration under President Barack Obama is facing its toughest test
yet.
Its credibility has come under severe pressure, with the public taking
a dim
view of the slow and inadequate response of the federal government and
what
appears to be collusion with BP. Obama is discovering that oratory and
rhetoric
are assets in a campaign but can boomerang in the face of poor results
on the
ground. The poor response of the US government under then President
George W
Bush to Hurricane Katrina came to typify the incompetence, cronyism and
lack of
caring of the Bush administration. Will the BP oil spill, again
affecting the
state of Louisiana, prove to be President Obama’s Katrina?
Let us look at what
has happened to date.
OIL
GUSHER
Normally the term
“oil spill” suggests an oil tanker breaking-up or developing a leak.
The BP
disaster is quite different and should really be called an oil gusher.
On April 20th, an
explosion on BP’s “Deepwater Horizon” off-shore
oil rig in the US exclusive economic zone in the Gulf of Mexico about
66 km off
Louisiana left 17 workers injured and 11 missing, presumed dead. The
explosion
led to a rupture in the well about 5000 feet below sea level from where
oil and
gas have been gushing out ever since.
The quantity of oil
that has spewed out is still being debated, largely because BP itself
has made
widely varying statements even while it has prevented independent
scientific
investigations to estimate the quantum of leakage claiming that this
was “not
relevant to the response” and that such attempts “might distract from
efforts
to stem the flow”! Amazingly, the Obama government and even its
different
scientific agencies such as the National Oceanographic and Atmospheric
Administration (NOAA) have not insisted on conducting their own
assessment, nor
have ensured full access to data. Scientists, media personnel and
others have
been prevented from conducting studies in the spill region not only by
BP
personnel but also by the US Coast Guard which stated they were “acting
under
instructions of BP”, lauded BP’s efforts and even conducted joint press
briefings, all till June 1 when the Administration decided this cozy
relationship was not going down well among the public and announced a
track-change putting the onus more sharply on BP.
BP initially
estimated that the well was gushing 1000 barrels (160,000 litres) of
oil a day.
NOAA reached an estimate about 5 times higher at 5000 barrels per day
based on
early satellite imagery. Under intense media, public and Congressional
pressure, a US government team under the US Geological Survey conducted
surveys
and tentatively estimated a much higher leak rate of 800,000 to 1.8
million
gallons (3 to 6.8 million litres) per day. The official Technical Group
later
put the estimate at a lower 500,000 – 800,000 gallons per day but this
was based
on merely a 7 minute low-quality undersea video provided by BP showing
the oil
gushing out, a video feed now being transmitted live by order of
Congress. Even
at these more conservative figures, 25 to 40 million gallons of oil
would have
spilled out into the Gulf to date. The previously largest US oil spill,
from
the Exxon-Valdez tanker in Alaska in 1989, was of 11 million gallons
(itself
dwarfed by the largest ever spill from a Mexican off-shore rig in 1979
also in
the Gulf releasing 140 million gallons of oil).
Worse than the
sheer volume of oil, the leak is not on the surface but deep under the
sea.
Scientists have recently found that large plumes or clouds of oil have
formed
deep under the sea and are moving quite far. As we go to press, NOAA
has reluctantly
confirmed that such plumes indeed exist (having earlier joined BP in
denying
any such phenomena) but claimed they have low concentrations of oil.
Several
plumes, some as large as 16 km by 4.8 km and 100 metres thick, have
been noted,
some even 130 km away from the well and sometimes occurring at
different depths
on top of each other. These plumes comprising oil droplets may cause
even more
damage to marine life than surface oil because far more species live
deeper
down and also because oxygen supply would be stifled, one research team
estimating it at 30 per cent less than normal. Marine biologists are
critical
of BP, and of US administration agencies, for not having envisaged and
tracked
these plumes earlier since their formation after undersea blowouts has
been
predicted in the scientific literature for years. In the BP oil gusher,
chances
are that chemical dispersants used to thin out the oil for subsequent
clean-up
may have actually helped the plumes form, another sign that BP has been
fumbling its way along the disaster with no prior preparedness or plan.
TACKLING
THE SPILL
There are two broad
levels at which the oil spill requires to be tackled. First, to contain
the
effects of the spill on the surface. Second, to try and stop the leak
itself.
Containment
measures largely comprise spreading booms or inflatable tubing that
float on
the surface of the water and physically block the spread of the oil or,
in some
types of booms, soak it up. Oil will usually stay on top of the water
for some
time till it gets broken down by the wind, waves and ocean currents.,
and this
oil can be either sucked or skimmed off the top by special ships. So
far more
than 2 million feet of containment boom and another 2 million feet of
absorbent
booms have been laid out, and more than 15 million gallons of
oil-bearing sea
water have been removed.
Chemical
dispersants are also used to break down the oil enabling its
biodegradation.
About 750,000 gallons of dispersant have been used on the surface and
another
300,000 gallons at varying depths. However, this procedure is not
without risks
especially to marine life and, as we have seen in the Gulf, may even
have
contributed to formation of plumes below the surface. To the best of
one’s
knowledge, biological agents have not so far been used in the BP
disaster. More
than 22,000 personnel have been deployed in these operations. Sand
banks have
also been prepared along certain stretches of coast to prevent ingress
of the
slick inland or into coastal wetlands and marshes.
Yet for all that
local residents are clearly unhappy with the progress. More than 40 per
cent of
the incomes of people in coastal belts of Louisiana and neighbouring
states
come from tourism and fishing, both of which have been badly affected,
especially the shrimp catch in shallow coastal waters and marshlands.
This
region contains 40 per cent of US coastal wetlands. Scientists are
worried that
these fragile coastal belts and wetlands are likely to suffer
considerable
damage that cannot yet be determined. Water samples all along the
Louisiana
coast have shown oil and, in some places, the booms near the shore seem
to be
keeping the oil in by blocking tidal flows as much as they are keeping
oil out!
At the time of the
rig explosion, the plan had been to plug the well with a cemented cap
for later
production. The same basic idea was pursued after the well burst but
with
several variants all of which essentially failed to plug the leak.
First a “top
hat” procedure --- where a massive concrete dome was lowered over the
blow-out
preventer (BOP) that had failed to engage as it should have after the
explosion
--- was tried but did not succeed. Then a special mud was forced down
at high
pressure, to be followed by cement once it had kept the oil down and
settled,
but the procedure could not overcome the upward pressure of the oil and
gas.
Then a so-called “junk fill” was tried replacing the mud with assorted
materials. Lastly the well’s riser pipe was cut and a cap forced on to
it with
a pipe leading up to the surface where the recovered oil is being
stored, with
BP now proposing to flare it. One ship on the surface is currently
handling the
oil being pumped up and another one is expected to join soon to help
augment
processing capacity.
However, because
the cut in the pipe is rough and the cap fits poorly, only a portion of
the oil
gushing out is being collected in this manner. BP started with the
claim that
it was tapping off around 10,000 barrels or 260,000 gallons per day
then upped
the claim to about 300,000-600,000 gallons per day which would mean
that around
half the total oil gushing out from the well is still leaking out into
the
Gulf.
BP and federal
government officials have repeatedly said that all these are only
intermediate
palliative measures, and that the only real solution to the problem is
to drill
a relief well besides the ruptured one so that the oil rises up the new
well
rather than the old one. This is perhaps correct, but the very fact
raises a
host of questions about how much BP and the US government knew about
the
blow-out, damage likely to be caused and steps that could have been
taken to
prevent it or to tackle the problem once it had arisen.
UNSAFE WITH
OFFICIAL SANCTION
It has been clear
from the very beginning that BP was not only complacent and
ill-prepared for
the disaster, but had also knowingly cut corners, circumvented safety
measures
and ignored safety procedures in active connivance with the
governmental
regulator, the Minerals Management Service (MMS).
The most glaring
avoidance of safety precautions was the decision by BP not to install
an
automatic shut-off valve which should have shut down the flow of oil
from the
well into the riser pipe immediately after the explosion on the rig.
Such
cut-off valves are mandatory and standard equipment on European
off-shore
drilling rigs as British Petroleum well knew. Yet the MMS went along,
and also
gave exemption to BP from conducting an experimental site analysis
because the
chances of an oil spill were “minimal or non-existent.”
Since the explosion,
BP executives have been repeatedly pointing to the difficulties of
operations
at depths of around 5000 feet below the sea even though these were well
known
and should have been anticipated. Yet the fumbling and ad hocism of BP
measures
since the disaster as described earlier have shown that it had no
emergency
plans and no equipment on stand-by to deal with a problem if it
happened, like
a high-rise building with no fire escape and no fire extinguishers. BP
chairman
Tony Hayward coolly admitted that "what is undoubtedly true is that we
did
not have the tools you would want in your tool kit" to deal with this
kind
of well blow-out even though these are familiar and not uncommon in the
oil
industry.
Incredibly, the MMS
has approved 27 new offshore drilling operations since the April 20
explosion,
exempting all but one of them from environmental review. To add insult
to
injury, two of the new operations approved were submitted by BP, which
made the
same assertions on drilling safety as it had for Deepwater Horizon
despite all
that had happened since!
President Obama has
belatedly said that he would end the “scandalously close relationship”
between
regulators and the companies they oversee. The MMS chief Elizabeth
Birnbaum has
since resigned, but people are wondering why Obama had not noticed the
deep
conflict of interest built into the very structure and role of MMS
before. MMS
is responsible for leasing off-shore drilling rights, permitting and
overseeing
operations and collecting royalties, all of which make it develop
vested
interests in the commencement, continuation and profitability of
off-shore
drilling rather than a prime responsibility for workers’ safety and
environmental protection.
It has also not
gone unnoticed that Obama, in March this year, had proposed to allow
expanded
drilling for oil in the Gulf, the Atlantic and the Arctic, the very
things he
had criticised his rival Republican candidate John McCain for during
the
presidential campaign. Obama now wants to appear tougher against BP and
other
oil giants, and is making a big noise about making BP pay every penny
required,
and “kicking a**”! But will the bluster actually translate into action?
The Obama
administration is said to be working on a new law to raise the limit on
liability claims from $10 billion to $75 billion but with the US
government
having already spent an estimated $20 billion, this may still be far
below the
actually costs. More importantly, will Obama show the guts to take on
Big Oil,
and can he muster the legislative support required? Many Senators and
Representatives are already towing BP’s line, trying to minimize the
damage and
shifting blame. Federal agencies such as NOAA, MMS and the Coast guard
seem to
be acting in collusion with BP although of late at least putting on an
appearance of trying to distance themselves. Evidence suggests that
Obama is
unable or unwilling to exert real pressure on BP, not able even to
secure
accurate data about the spill whose quantum will of course be critical
in
determining the extent of damages BP is likely to pay out. Big Oil
clearly has
longer arms than the law in the US.
