Hurricane Isaias Prompts Gulf Oil Shutdowns and Refinery Precautions

The detail that matters is the timing. With Hurricane Isaias still expected to stay east of the Gulf's main offshore cluster, companies had already shut in about 1.3 million barrels a day, roughly 63 percent of U.S. Gulf oil production. Shell, BP and Chevron were taking people off platforms. Exxon was still producing and watching the weather. Chevron's Pascagoula refinery remained up, under a hurricane warning. That is a hazardous industry doing the unglamorous part of the job: getting crews out on the forecast, not after the sea has made the decision.

A shut-in that large, from a storm pointed at Mississippi, Alabama and the Florida Panhandle rather than at the Louisiana and Texas waters that hold most of the hardware, is a fact about how this supply is organized. Platforms do not spring back to full rates when the all-clear is posted. If fuel is disrupted, analysts are right that flooding, power loss and interrupted tanker traffic are the likely culprits, not a direct hit on the big western Gulf plants. And the scary percentage needs a denominator. Measured against national crude output of recent years, 1.3 million barrels a day is closer to a tenth than to a collapse — enough to show up at the margin, not evidence that the country runs out of oil on Saturday. The number is an argument about concentration.

That concentration was a choice, and not a clean left-right one. The bulk of American offshore crude is in the Gulf because that is the bargain the coasts actually struck. Louisiana and Texas took the industrial footprint. Florida fought to keep rigs away from its beaches, usually with Republicans out front, and new leasing off the Atlantic and Pacific has been politically dead for years across party lines. Some of those refusals should stand. Congress walled off much of the eastern Gulf in part because the Pentagon uses it as a test range, and a conservatism that treats defense as a real obligation does not hand a bombing corridor to a lease sale. Tourism along those beaches is an economy, not a mood.

The failure was everything that followed. Once it was clear that not every coastline would host platforms, the path of least resistance in Washington was to slow the barrels that do not share the Gulf's weather — onshore federal leasing, Alaska, pipelines that give inland oil more than one route to a customer. An exclusion zone is a reason to spread risk. It became an excuse to treat one hurricane corridor as the designated offshore province.

Retiring the barrels altogether would turn the shut-in into a solution only if something else were already moving the freight, fueling the ships and feeding the refineries now under warnings, from places a single forecast cannot idle at once. A storm takes supply off for days or weeks. A permitting regime can take it off for years. The Bureau of Safety and Environmental Enforcement is doing a proper public job when it counts the shut-in barrels and the industry clears its platforms; forecasts, open channels and rescue capacity are what limited government is for in a hurricane. A standing policy of shrinking the backup, then gesturing at the satellite image, is not.

One rigidity in that picture is less famous than the storm and easier to fix. Fuel moving between American ports has to travel on Jones Act ships, a small U.S.-built and U.S.-crewed fleet. When docks at plants such as Pascagoula or Saraland are threatened, product cannot simply be shifted from an unaffected domestic refinery on the nearest available tanker. Waivers arrive after the shortage has a zip code.

A near miss would be a mercy. It would not repair a map that puts this much offshore supply inside one forecast.
