"A rig explodes and sinks, a blowout preventer fails and Gulf of Mexico states wait weeks with containment booms and crossed fingers for the devastation to wash ashore.
Substitute "Ixtoc I" for "Deepwater Horizon," and "PEMEX" for "BP," and the world's largest peacetime oil spill sounds eerily similar to the 2,500 square miles of Gulf surface now threatening Florida's shores."
Similarities
Accident
It was operated by Pemex, the Mexican giant as oppose to BP, the British giantThe break occured because hydrocarbons forced their way up the pipe and ruptured it along the way.The rig burned uncontrollably and eventually sunkThe Blowout Preverter failed to work properly
Attempted Fixes
They attempted to put a cone over the top, calling it operation Sombrero (as oppose to Top-Hat)They attempted to plug up the leak by pumping rocks, mud and seawater into it
The FixAfter nine months of failed attempts Pemex finally got several relief wells drilled and was able to reduce the pressue enough to cap it. It doesn't appear that a whole lot of other options exist right now. The technology for fighting a renegade well just isn't that good (nor has it improved a whole lot since 1979). BP/Transocean are drilling two wells as we speak but it is not clear just how long this will take, or how many will ultimatly be needed.
Could it take nine months to fix this? Easily, in fact it could take a whole lot longer due to the increased size of the spill and the depth at which it occured (5,000 feet down as oppose to 200 for Ixtoc).
Possible Effects
In 1979 they had two months to prepare for as much oil as this spill spews out in 3-10 days (depending on estimates). Clearly effects will be much worse. In a worst case scenario we could see
A loss of estuaries which are home 90% of the marine species during some portion of their livesLarge destruction of beaches and the subsequent reduction in tourismThe oil could, and probably will, kill a large amount of the aqatic life in the heavily effected areas, meaning that fishing in those areas would go downhill very quickly Although no one has mentioned it (and I am no scientist so take this with a mountain of salt) I would not be surprised to see the oil wind up in the gulf stream, seeing as the gulf stream circulates right by the lower edge of Florida. Now remember that BP says they will pay for all costs and not hide behind legal barriers to reduce risk.
Who wants to buy BP stock now?
