No Assurance in Offshore Update
© David D. Schreck of StrategicThoughts.com
Trust us, engineers can solve any problem (sure). That could well be the short version of the "British Columbia Offshore Oil and Gas Technology
Update" dated October 19, 2001. The 196 page report and three appendices
are available for download from the Ministry of Energy & Mines website.
Appendix 2 contains a copy of a news release dated May 14, 2001, from
the Tsimshian Nation and the Haida Nation stating that they support the moratorium and that the reasons for initiating the moratorium have not changed. A careful reading of the updated report shows the first nations are right.
By way of background, the updated report claims to be unbiased and says:
"This report entitled British Columbia Offshore Oil and Gas Technology
Update is an update of the 1998 AGRA Earth and Environmental Limited
report Review of Offshore Development Technologies prepared for the
British Columbia Information, Science and Technology Agency. This update
report is a component of the provincial government's review of the
offshore oil and gas moratorium and is an extension of the process that
includes the 1986 Offshore Hydrocarbon Exploration, a Report and
Recommendations of the West Coast Offshore Exploration Environmental
Assessment Panel and the 1998 AGRA report. Jacques Whitford Environment
Limited has prepared this document as an unbiased update of offshore oil
and gas engineering, environmental and socio-economic factors, and
state-of-the-art technologies." (p. 173)
On page 172 the updated report says "In conclusion, the study has found
that there are no specific design, geohazard or environmental issues
that would preclude the development of the offshore oil and gas
reservoirs of British Columbia. However, the economic viability of a
specific reservoir may be adversely impacted by the costs associated
with mitigating the geohazard and environmental risks."
Immediately before that conclusion, the report makes a pitch for the new
catch word around the Campbell government - "results based regulation" -
when it says:
"One of the important issues to be addressed by Government in the
regulation of oil and gas developments offshore will be the degree to
which regulations are prescriptive. The eastern Canadian offshore
regulations are heavily prescriptive which can place a significant cost
burden on potential offshore activities. With the advances in the
technology of offshore investigations, drilling and production, there is
significant opportunity to use a results oriented, review and approval
process to ensure the highest economic benefit while ensuring that the
potential for environmental and safety risks are adequately controlled."
One can only suppose the results for those results based regulations
might include the number of species eliminated after a disaster, and an
estimate on how long the destruction of fisheries and tourism might
last. The updated report acknowledged that "The area around the Queen
Charlotte Islands, Dixon Entrance, Hecate Strait and Queen Charlotte
Sound is known to be one of the most seismically active areas of the
world." (p. 62). It also acknowledged severe storms and said "The waters
surrounding the Queen Charlotte Islands are commonly reported as the
windiest in Canada ." (p. 55). If that isn't bad enough, the report said
"Given the close relationship between storm winds and surface waves,
wave conditions in the northern British Columbia waters can also be
considered relatively severe." (p. 57)
The approach of the report is to categorize each of these threats as
risks to be managed. For example, when discussing tsunamis, the reports
says:
"Satake (2001) reports an analytical study of tsunami in the Pacific Rim
triggered by a large landslide in the Hawaiian Islands and estimated
that the tsunami height could be 30 m (100 feet) in the western margins
of Dixon Entrance and Queen Charlotte Sound. Lynett et al. (2001) also
proposed a numerical model for tsunamis. The site-specific
tsunami-related design parameters including wave heights and run-up can
be estimated for the oil and gas developments in British Columbia
offshore lease areas following such procedures. These parameters should
then be used in structural design and risk management of offshore oil
and gas facilities."
The good news according to the report's summary of these risks is that
at least we don't have icebergs:
"In summary, the northern waters of British Columbia present a complex
physical environment, with highly variable bathymetry, strong winds and
currents, and high waves during storm events. The region is also one of
high seismic activity, with the associated risk of slope failure and
tsunami generation.
Conversely, the significant risk to offshore facilities posed by
icebergs on the Grand Banks of Newfoundland is not found on the west
coast of Canada."
Anyone concerned about our environment should carefully read the updated
report. There one does not find answers on how the risks will be
managed. Rather one finds assurances that engineers have solved problems
in other parts of the world. The following is one example of that
attitude that can be characterized as trust the engineers:
"The physical conditions under which offshore hydrocarbon exploration,
development and production activities occur impact engineering designs,
operational procedures and environmental impacts associated with any
contaminant releases to the marine environment. Uncertainties in the
physical parameters discussed in this section can be dealt with through
standard approaches such as increased factors of safety included in
engineering designs and operational procedures, while environmental
concerns can be reduced through the incorporation of additional spill
prevention measures into offshore equipment. The net effect of high
uncertainties in the physical conditions under which offshore activities
are to occur is to increase the cost of offshore activities and reduce
the economic feasibility of a given project, rather than to limit the
technical feasibility of offshore exploration." (p. 67)(emphasis added)
Far from offering assurances about the safety of drilling in Hecate
Strait, a careful read of the report confirms the conclusions reached by
the Tsimshian Nation and the Haida Nation that the moratorium is
necessary and the reasons for initiating it have not changed.
