It looks like the systems, ie standard practices, were in place, but that the appropriate practice was overridden at several places. Haliburton did a poor cementing job but BP chose not to fix it. That is BP's failure, not Haliburton's. BP chose to ignore the warnings about pumping out the heavy mud, overriding Transoceanic. BP seems to have a culture of ignoring government regulations, industry practices, and operational warning signs, not to mention going for cheap rather than fully functional safety equipment. The blame for the dysfunctional culture lies squarely on the shoulders of Tony Hayward. We do have a problem of the regulators being in bed with the regulated. The rig should have been shut down because of violations long before the blowout, just as the WVA coal mine should have been shutdown because of safety violations
