Gulf Oil Leak

          A containment dome is a 4-story, 70-ton structure that catches the escaping oil and allows it to be pumped to the surface. BP was planning on installing a shutoff valve at the site of one of the leaks, but the seas were too rough. They laid floating booms in the coastal waters to protect the shoreline from the spreading oil slick, but heavy winds damaged those.
          A blowout preventer is a device that is meant to seal leaks. BP's blowout preventer was unable to seal the well due to an obstruction too thick for the BOP, blowout preventer, to crush or shear. Transocean would face a large overhang of investor worry.
          In my opinion, everyone should have just one their job to the best of their ability. It seems to me like this problem came from a long line of people not doing their job correctly. I also think they should test the cement plug more than once, leaving some room for error without great consequences.
