PostSubject: Missteps before Blowout   Mon Jun 14, 2010 11:42 pm

BP started drilling in October, only to have the rig damaged by Hurricane Ida a month later. The company switched to the Deepwater Horizon rig and resumed drilling on Feb. 6. The rig was 43 days late for its next drilling location by the time it exploded April 20, costing BP at least $500,000 each day it was overdue, congressional documents show.

As BP found itself in a frantic race against time to get the job done, engineers cut corners in the well design, cementing and drilling mud efforts and the installation of safety devices known as "lockdown sleeves" and "centralizers," according to congressional investigators.

In the design of the well, the company apparently chose a riskier option among two possibilities to provide a barrier to the flow of gas in space surrounding steel tubes in the well, documents and internal e-mails show. The decision saved BP $7 million to $10 million; the original cost estimate for the well was about $96 million.
