It's the second time a rig has blown while they were on-board and doing this very same process.

"Many of the more than two dozen lawsuits filed in the wake of the explosion claim it was caused when workers for oil services contractor Halliburton Inc. improperly capped the well -- a process known as cementing. Halliburton denied it.
According to a 2007 study by the federal Minerals Management Service, which examined the 39 rig blowouts in the Gulf of Mexico between 1992 and 2006, cementing was a contributing factor in 18 of the incidents. In all the cases, gas seepage occurred during or after cementing of the well casing, the MMS said."
