As of April 2010, it had not had a single “lost-time incident” in seven years of drilling. In September 2009, it had drilled to a world-record total depth of 35,055 feet. Prior to the accident, Deepwater Horizon was one of the best-performing deepwater rigs in BP’s fleet. The lessons from this tragedy are potent reminders of the pitfalls that can plague complex programs and projects in any industry, even (perhaps especially) those with long track records of success. At 9:49 p.m., the rig exploded, leading to 11 deaths and the worst oil spill in U.S. At the time, the job was 43 days over schedule and $21 million over budget due to additional leasing fees. On April 20, 2010, the Deepwater Horizon rig was finishing up a drilling job at the Macondo lease site, a plot in the Gulf of Mexico 49 miles off the coast of Louisiana. The well owner returns later (typically with a less expensive production rig) to collect the oil. At that point, drilling stops, the well is cemented and capped, and the rig is removed. The rig drills progressively deeper until it reaches a depth where returns from the well can be maximized. Drilling mud is used to lubricate the drill bit and control pressure exerted by hydrocarbons unearthed during drilling. It involves using a drilling rig to penetrate the ocean floor, and installing and cementing pipe to secure the wellbore (well hole). Offshore oil drilling is complex work that employs state-of-the art technology in an extremely dynamic environment.
