Deepwater Horizon Blowout Preventer Failure
The New York Times finds preliminary answers to many of the questions about the failure of the Deepwater Horizon blowout preventer. Two things in particular standout: the blowout preventer has only one blind shear ram (that failed to seal the well) while many underwater wells have blowout preventers with a second, backup, blind shear ram; blowout preventers are known within the industry and government regulating agencies to be unreliable, suffering from design deficiencies and inadequate maintenance.
