Hopefully not, but exactly three years ago today, Hurricane Katrina made landfall after buzzing through the offshore oilfields in the Gulf of Mexico as a Category 5 storm (we documented some of the resulting offshore oil spills), and now it looks like Hurricane Gustav may be heading for the same trajectory. It just regained hurricane strength today, and forecasters have been predicting at least a Category 3 storm when it reaches the hot water of the central Gulf of Mexico.
We’re also hopeful that the mooring systems for floating drill rigs have been significantly strengthened. During Katrina, some of these huge rigs broke loose and got blown around the Gulf, dragging their anchors across the seafloor and tearing up the pipeline network. We think that caused many of the offshore slicks we observed on satellite imagery.
But most of the oil spilled by hurricanes Katrina and Rita happened onshore: over 9 million gallons, according to the U.S. Coast Guard, spilled from coastal refineries, storage tanks and pipelines – 6 major spills (>100,000 gallons), 5 medium spills, and over 5,000 minor spills. And those onshore facilities are just as vulnerable now as they were three years ago. Let’s keep our fingers crossed and say a prayer for the folks down along the Gulf coast. And keep an eye on Gustav. (What’s that you say? Hanna too?? You gotta be kidding me….)
