Offshore drilling ‘incident’ a harrowing warning
Both Shell and the industry regular are to blame for a near oil drilling
disaster that could have contaminated the Nova Scotia coastline

Shell Oil’s Stena IceMAX drill ship, drilling for oil on March 5th, two
kilometres below the surface of the Atlantic on the edge of the Scotian
Shelf, was the site of what regulators euphemistically call an “incident.”
Battling unexpectedly high waves, the drill ship crew successfully
secured the well and disconnected the ship from the wellhead to protect
the operation. Shortly after, the riser, a 2,100 metre-long protective
series of 21-inch diameter pipes, each weighing 20 tonnes, broke free of
the drill ship before it moved clear of the site. The riser pipes fell
to the ocean floor missing the wellhead by a mere 12 metres.
A Shell investigation of the “incident” was monitored and matched by an
internal review by the regulator, the Canada-Nova Scotia Offshore
Petroleum Board (CNSOPB). The federal/provincial CNSOPB is the
equivalent of the National Energy Board, regulating oil industry
activity in our offshore.
In June, after receiving Shell’s report on the event, Stuart Pink, the
CNSOPB’s chief executive officer, declared, “We are satisfied that the
cause of the incident has been properly determined and that appropriate
corrective actions have been taken so that drilling may resume safely.”
The CNSOPB released only a summary of Shell’s investigation report,
omitting key facts, such as the near hit at the wellhead when the riser
pipes hit the seabed, and the poor preparedness of personnel for
handling the technology connecting the riser stem and the drill ship.
Those facts, and the full extent of what might better be described as a
potential disaster, rather than a mere “incident”, came to light when
the Halifax Examiner obtained the full report through a freedom of
information request.
The lessons the CNSOPB drew from the event related to technology,
procedure, training and competence, and a commitment to ensure the risk
of a recurrence was minimal. The rest of us might reach other
conclusions from this near disaster.
Simply put, the failure to foresee and plan for the heavy seas that are
common where the deep Atlantic rolls up onto the continental shelf south
of Nova Scotia, is a failure of both the operator, Shell, and more
importantly, the regulator, the CNSOPB. They illustrate a fundamental
characteristic Canadians are discovering in regulatory agencies across
the country — they are captives of the industries they regulate. As
such, they are ill-suited to the task of risk assessment in the broader
public interest.
Assessing risk is an inexact art that is only half the challenge. The
other half is determining what is an acceptable risk. That determination
must include those most likely to bear the costs of a catastrophe.
Shell is drilling Cheshire and its sister well, Monterey Jack, in water
deeper than almost any other well in the world, significantly deeper
than BP’s Deepwater Horizon well.
Reliable experience in such deep water is almost non-existent. As the
National Commission on the BP Deepwater Horizon Spill concluded in its
report to U.S. President Obama, “Deepwater energy exploration and
production, particularly at the frontiers of experience, involve risks
for which neither industry nor government has adequately prepared, but
for which they can and must be prepared in the future.”
Shell’s exploratory wells lie close to our most productive sustainable
fishery, to key spawning and nursery grounds for scallops, lobster,
haddock and halibut, and not far from the massive daily tidal in- and
outflow from the Bay of Fundy. Clearly, deciding acceptable risk must
involve southwestern Nova Scotia communities dependent on those
resources. A blowout would have catastrophic consequences.
Today, the interests of the people of this region rest on assurances
from the CNSOPB, whose members are overwhelmingly oil industry veterans,
unrepresentative of those who bear the risks resulting from the agency’s
decisions.
There may have been a time, before we truly understood the risk of
further developing our non-renewable, dirty energy resources, or before
we truly appreciated the importance of sustainable resource industries,
such as the fishery or tourism, when risk assessment could be left to a
self-serving industry. But knowing what we know now, to continue with
that model of regulation is clearly senseless.
The lesson of Shell’s recent “incident” at its Cheshire well is that we
need to democratize the process of deciding if we can safely drill for
oil, and whether and where the risks of doing so are acceptable. Until
we take steps to ensure full and informed public involvement in those
decisions, further approvals for drilling exploratory wells in our
vulnerable offshore can’t be trusted and should be annulled.
