The Coast Guard says that Transocean poorly maintained electrical equipment that may have ignited the explosion on the Deepwater Horizon.
It finds the company bypassed gas alarms and automatic shutdown systems that should have alerted crew members to the danger. And it says the company didn’t provide rig workers with adequate training on how and when to disconnect the rig from the Macondo well to avoid an explosion.
The report also found lax oversight by the rig’s flag state, the Republic of the Marshall Islands, a Pacific nation where Transocean registered the Deepwater Horizon in 2005. It says the Marshall Islands failed to make sure the vessel was properly inspected and that its electrical equipment, crew training and emergency preparedness were in good working order. The study recommends the Coast Guard ramp up inspections of such foreign-flagged drilling rigs.
