Aircraft sprayed more dispersants over floating oil, and technicians hurried to build and deploy heavy cofferdams specially designed to sit atop the broken riser and BOP stack, collect the leaking oil and pipe it up to tanker barges. Drill ships are heading to the scene, to drill relief wells, intersect the original hole, cement it shut and permanently stop the leak. ExxonMobil, Shell, ConocoPhillips and many other companies have offered BP, Transocean and Halliburton assistance on all these fronts.
How bad will the disaster be? Much depends on how long the calm weather lasts, how quickly the cofferdams can be installed, and how successful the entire effort is. There is some cause for optimism – and much need for prayer, crossed fingers and hard work.
But it will take weeks to years of uncontrolled leakage, before this spill comes close to previous highs, such as the:
* Santa Barbara Channel oil platform blowout (1969): 90,000 barrels off the California coast;
* Mega Borg tanker (1990): 121,400 barrels in the Gulf of Mexico off Galveston, TX;
* Exxon Valdez tanker (1989): 250,000 barrels along 1,300 miles of untouched Alaska shoreline;
* Ixtoc 1 oil platform blowout (1979): 3,500,000 barrels in Mexico’s Campeche Bay;
* Saddam Hussein oil field sabotage (1991): 857,000,000 barrels in Kuwait;
* Natural seeps in US waters: 1,119,000 barrels every year from natural cracks in the seafloor.
Cold water and climate meant Alaska’s Prince William Sound recovery was slow; Campeche beaches and coastal waters largely rebounded much more rapidly. Mississippi River flows through the warm Delta region may help keep some oil from pushing too far into the estuaries and speed recovery of oyster, shrimp and fishing areas, as it did with spills during pre-1960 drilling. Prayers and crossed fingers again.
Should we stop drilling offshore? We can hardly afford to. We still need to drill, so that we can drive, fly, farm, heat our homes, operate factories and do everything else that requires reliable, affordable petroleum. Indeed, over 62% of all US energy still comes from oil and gas. And we certainly need the jobs and revenues that US offshore energy development generates.
We’ve already banned drilling in ANWR, off the Florida, Atlantic and Pacific coasts, and in many other areas. We’ve made it nearly impossible to mine coal or uranium, or build new coal-fired power plants or nuclear reactors. We’ve largely forced companies to drill in deep Gulf waters, where risks and costs are far higher, and the ability to respond quickly and effectively to accidents is lower.
We’ve also forced companies to take drilling risks to foreign nations – and then increased the risks of tanker accidents that cause far greater spillage when they bring that oil to America. Meanwhile, Russia, China and Cuba are preparing to drill near the same Gulf and Caribbean waters that we’ve made off limits – employing their training, technologies, regulations and ecological philosophies.
Even with this blowout and its 1969 Santa Barbara predecessor, America’s offshore record is excellent. Since 1969, we have drilled over 1,224,000 wells in state waters and on the Outer Continental Shelf. There have been 13 losses of well control involving more than 50 barrels: five were less than 100 barrels apiece; one was a little over 1,000 barrels; two (both in 1970) involved 30,000 barrels or more. Only in Santa Barbara (so far) did significant amounts of oil reach shore and cause serious environmental damage.
Globally, tankers have spilled four times more oil than drilling and production operations, often in much bigger mishaps, often in fragile areas – and chronic discharges from cars and boats dwarf tanker spills by a factor of eight. (All spill data are from the MMS and National Research Council.)
What should we do next? Recognize that life, technology and civilization involve risks. Humans make mistakes. Equipment fails. Nature presents us with extreme, unprecedented, unexpected power and fury.
Learn the right lessons from this tragic, catastrophic, probably preventable accident. Avoid grandstanding and kneejerk reactions. Replace people’s lost income. Insist on responsible, adult thinking – and a thorough, expert, non-politicized investigation. Find solutions instead of assigning blame.
Why did the BOP and backups fail? What went wrong with the cement, plugs and pressure detection devices, supervisor and crew monitoring and reactions, to set off the catastrophic chain of events? How can we improve the technology and training, to make sure such a disaster never happens again? How can we improve oilspill cleanup technologies and rapid response?
Ask what realistic alternatives we have. Not “Sim USA” and virtual energy. Real energy.
Can we afford to shut down our domestic oil and gas industry – economically, ecologically and ethically – and import more, as we export risks to other countries, and shift risks from drilling accidents to tanker accidents? Can we afford to replace dozens of offshore rigs with thousands of towering offshore wind turbines, creating obstacle courses for ships laden with bunker fuel or crude oil?
Drilling in deep waters far from shore is a complex, difficult, dangerous business. Let us remember and pray for the eleven who died, those who were burned and injured, and their families and loved ones. Let us also pray for all who daily risk life and limb, to bring us the energy that makes our lives, jobs and living standards possible – and for all whose lives have been affected by the spill.
