Workers from both Transocean and BP testified in a New Orleans hearing before the U.S. Coast Guard and Bureau of Ocean Energy Management, Regulation and Enforcement concerning the Deepwater Horizon’s failed safety systems.
From the testimony, it is now apparent that no alarms sounded on the Oil Rig, Deepwater Horizon, before the initial explosion. An electrician on the rig stated that he had received orders to disconnect the alert system months prior to the explosion, that killed 11 men, simply to cut down on false alarms that kept waking the crew up in the middle of the night.
The amount of safety violations continue to be uncovered by testimony and documents released by court order.
Here is an article by the Wall Street Journal regarding the testimony of the electrician and the safety failures on the Deepwater Horizon.
