Alarms, detectors disabled so top rig officials could sleep
The Deepwater Horizon's fire and gas leak alarms were disabled for at least a year to prevent false alarms from waking up rig leaders, a chief engineer told federal investigators.

Reporting from Kenner, La — Critical fire and gas leak alarm systems had been disabled for at least a year aboard the Deepwater Horizon because the rig's leaders didn't want to wake up to false alarms, a rig chief engineer tech told federal investigators.
"I discovered it was 'inhibited' about a year ago," said Mike Williams, the chief engineer tech who worked for rig owner Transocean aboard the Deepwater Horizon, which erupted in flames April 20, killing 11 men and starting the worst offshore oil spill in U.S. history.

"I inquired," Williams told an investigative panel from the U.S. Coast Guard and the Interior Department in suburban New Orleans. "The explanation I got was that from the
down, they did not want people to wake up at 3 a.m. due to false alarm," Williams said. Williams later said the rig's captain had also agreed that the alarms were to be disabled.
Williams said he complained repeatedly about disabling the systems, from six months to three days prior to the rig's explosion. He said he told supervisors it was unsatisfactory for the alarms to be disabled, but was rebuffed.
The alarm systems could have been helpful to alert crew members of catastrophe and initiate an emergency shutdown system that could have shut down the engines -- a dangerous ignition source -- as soon as a surge of flammable natural gas surged up the oil well onto the rig.
