For those looking for data and detail, an excellent article on the Deepwater Horizon accident.
Deepwater Well Construction 101
Saturday, May 22nd at 6:35PM EDT
By any measure, the construction of a deepwater well involves “Extreme Engineering”. And like other applications of technology at the frontier of knowledge, proper operating practices are often a response to failure, and examination of lessons learned.
The Deepwater Horizon disaster represents the first time deepwater drillers have experienced multiple failures of the redundant systems that are designed to keep a well from flowing uncontrollably. In hindsight, it may well be determined that some combination of questionable design choices, human error and equipment malfunction conspired to cause the blowout and spill. No one (that I’m aware of) has suggested that BP was operating outside of its permitted authority.
