Jun 10, 2014 · The blowout preventer (BOP) that was intended to shut off the flow of high-pressure oil and gas from the Macondo well in the Gulf of Mexico during the disaster on the Deepwater Horizon drilling rig on April 20, 2010, failed to seal the well because drill

The blowout preventer (BOP) was the last failure before the explosion. The BOP is a complex arrangement of subsea components, designed with multiple functions to shut in a well.

May 21, 2010 · The blowout and oil spill on the Deepwater Horizon in the Gulf of Mexico was caused by a flawed well plan that did not include enough cement between the 7-inch production casing and the 9 7/8-inch protection casing. The presumed blowout preventer (BOP) failure is an important but secondary issue.

Sep 8, 2010 · Eight catastrophic failures led to the explosion that destroyed the Deepwater Horizon drilling rig in the Gulf of Mexico, killing 11 people and leading to one of the biggest oil leaks in...

Jun 10, 2014 · A new Deepwater Horizon disaster report, released on June 5, found that the blowout preventer (BOP), designed to shut off the flow of oil and gas from the Macondo well, "failed to seal the well...

Mar 31, 2011 · A report released by the Department of Interior last week confirmed suspicions that a Blowout Preventer (BOP) – a supposed fail-safe device on oil rigs – buckled moments before the explosion on the Deepwater Horizon last April, leaving 11 workers dead and millions of barrels of oil gushing into the Gulf.

A detailed examination of the Blowout Preventer (BOP) failure highlights critical operational and mechanical failures that contributed to the disaster, including malfunctioning control pods and communication issues.

The requirements provided in this specification apply to the following control system categories: • control systems for surface mounted BOP stacks; • control systems for subsea BOP stacks (common elements); • discrete hydraulic control systems for subsea BOP stacks; • electro-hydraulic/multiplex control systems for subsea BOP stacks ...

Conclusions regarding BOP failure: 1. Root causes of BOP failure are related to drilling industry standards and culture. 2. The ameron OP was the most critical component of the subsea system, but there were no FMEAs, identified safety critical elements, diagnostics, or reliability analyses. 3.

Houston, Texas, June 5, 2014— The blowout preventer (BOP) that was intended to shut off the flow of high-pressure oil and gas from the Macondo well in the Gulf of Mexico during the disaster on the Deepwater Horizon drilling rig on April 20, 2010, failed to seal the well because drill pipe buckled for reasons the offshore drilling industry ...
