The testimony of Dr. Robert Bea is available in a strongly worded pdf report. Here are a few of his conclusions:
"I believe the Deepwater Horizon failure developed due to:• improper cement design (segmented discontinuous cement sheath)
• flawed Quality Assurance and Quality Control (QA / QC) – no cement bond logs, ineffective oversight of operations
• bad decision making – removing the pressure barrier – displacing the drilling mud with sea water 8,000 feet below the drill deck
• loss of situational awareness – early warning signs not properly detected, analyzed or corrected (repeated major gas kicks, lost drilling tools, including evidence of damaged parts of the Blow Out Preventer [BOP] during drilling and/or cementing, lost circulation, changes in mud volume and drill string weight)
• improper operating procedures – premature off-loading of the drilling mud (weight material not available at critical time)
• flawed design and maintenance of the final line of defense – including the shear rams of the Blow Out Preventer (BOP).
• improper well design (configuration of well tubulars etc...
Furthermore, Dr. Bea believes the response effort has been lacking, to say the least. Here are his comments:
"My analysis of the facts developed to date show that BP PLC and the DOI MMS did not develop or implement effective measures for:
• well control after loss of containment – blowout
• capturing the loss of control materials (gases, oil, water)
• clean-up of the loss of control materials in the open ocean (booms, skimmers, burning, dispersants)"
The report indicates gross mis-management and almost nefarious behavior on the part of BP
