Wikipedia has a list of major oil spills
. Six involved offshore platforms, two of which were caused by tanker collisions (Iran's Nowruz Field
in 1983, Mexico's Kab 101
in 2007) .
The four others involved platforms - all blowouts that occurred during drilling operations: Santa Barbara spill
(Santa Barbara Channel, California, 1969), Ekofisk B
(North Sea, 1977), Ixtoc I
(Gulf of Mexico, 1980), and the Deepwater Horizon
There hasn't been an accident like this in 30 years.
That tells me that the the industry in general had figured out a long time ago how to do this kind of drilling safely, and that this disaster owes itself to a unique set of circumstances - human error, human sabotage, or something else.
We can find out what went wrong and avoid the same mistake(s) in the future.
Meanwhile, wind farms and skyscrapers are killing off birds
in greater numbers than the Exxon Valdez
did. Our feathered friends will tolerate this for only so long
