Yes, that's correct...a device that costs one half million dollars may have prevented what is on track to become the worst oil spill in U.S. history. The device is called an acoustic trigger (aka. acoustic switch, actuator). It is a remote-controlled device deployed off oil rigs that sends acoustic impulses through the water, triggering an underwater valve or explosives to shut down
According to the Wall Street Journal, Norway and Brazil require these devices in all offshore drilling operations. While they are not required with rigs offshore the U.K., BP elects to deploy them there. BP chose not to equip oil rigs off the coast of the U.S. with acoustic triggers because U.S. regulations enacted in 2003 do not require companies to do so.
CBS reported that Sen. Bill Nelson (D-FL) sent President Obama a letter Thursday reminding him that in 2000 the Interior Department insisted "oil companies have 'reliable backup systems' in the event of a rig blowout." By 2003, the plan was scrapped after a closed-door meeting with energy company executives conducted by then-Vice President Dick Cheney.
