THE MISSING LAST RESORT ACOUSTIC SWITCHES

From the Wall Street Journal:

The oil well spewing crude into the Gulf of Mexico didn't have a remote-control shut-off switch used in two other major oil-producing nations as last-resort protection against underwater spills.

The lack of the device, called an acoustic switch, could amplify concerns over the environmental impact of offshore drilling after the explosion and sinking of the Deepwater Horizon rig last week.

The accident has led to one of the largest ever oil spills in U.S. water and the loss of 11 lives. On Wednesday federal investigators said the disaster is now releasing 5,000 barrels of oil a day into the Gulf, up from original estimates of 1,000 barrels a day.

U.S. regulators don't mandate use of the remote-control device on offshore rigs, and the Deepwater Horizon, hired by oil giant BP PLC, didn't have one. With the remote control, a crew can attempt to trigger an underwater valve that shuts down the well even if the oil rig itself is damaged or evacuated.

The efficacy of the devices is unclear. Major offshore oil-well blowouts are rare, and it remained unclear Wednesday evening whether acoustic switches have ever been put to the test in a real-world accident. When wells do surge out of control, the primary shut-off systems almost always work. Remote control systems such as the acoustic switch, which have been tested in simulations, are intended as a last resort.

Although the efficacy of the devices may or may not be clear, depending upon to whom you're listening, the better part of caution would have been for BP to install the acoustic switches at the cost of $500,000, which is a fraction of the cost of a deep-water rig, which can run over $100 million. The spokesmen for the oil companies are already saying that the acoustic switches don't work.
