Halliburton is named as a defendant in most of the more than two dozen lawsuits filed by Gulf Coast people and businesses claiming the oil spill could ruin them financially. Without elaborating, one lawsuit filed by an injured technician on the rig claims that Halliburton improperly performed its job in cementing the well, “increasing the pressure at the well and contributing to the fire, explosion and resulting oil spill.”
Remote-controlled blowout preventers designed to apply brute force to seal off a well should have kicked in. But they failed to activate after the explosion. Scott Bickford, a lawyer for several Deepwater Horizon workers who survived the blast, said he believes a “burp” of natural gas rose to the rig floor and was sucked into machinery, leading to the explosion.Before last week’s catastrophe, Deepwater Horizon’s most recent “significant pollution incident” occurred in Nov. 2005, when the rig spilled 212 barrels of an oil-based lubricant due to equipment failure and human error. That spill was probably caused by not screwing the pipe tightly enough and not adequately sealing the well with cement, as well as a possible poor alignment of the rig, according to records maintained by the federal Minerals Management Service.
Following that spill, MMS inspectors recommended the company increase the amount of cement it uses during this process and apply more torque when screwing in its pipes. Experts say the number of safety incidents experienced by Deepwater Horizon isn’t unusual for an industry operating in harsh conditions. And it is difficult to draw any connections between those problems and last week’s deadly explosion, they say.
“These are big, floating cities,” said Tyler Priest, a historian of offshore oil and gas exploration. “You’re always going to have minor equipment failure and human error, and of course they’re operating in a hurricane prone environment.” Because vessels like the Deepwater Horizon operate 24 hours a day, Coast Guard officials said minor equipment problems appear frequently. But if they go unfixed such incidents could mushroom into bigger concerns.
• In Feb. 2002, just months after the rig was launched from a South Korean shipyard, it spilled 267 barrels of oil into the Gulf after a hose failed, according to records maintained by the Minerals Management Service.
• In June 2003, the rig floated off course in high seas, resulting in the release of 944 barrels of oil. MMS blamed bad weather and poor judgment by the captain. A month later, equipment failure and high currents led to the loss of 74 barrels of oil.
• In January 2005, human error caused another accident. A crane operator forgot he was in the midst of refueling a crane, and 15 gallons of overflowing diesel fuel sparked a fire.
The Coast Guard, which is supposed to ensure the vessels are seaworthy, keeps its own set of safety records on the Deepwater Horizon. From 2000-10, the Coast Guard issued six enforcement warnings and handed down one civil penalty and a notice of violation to Deepwater Horizon, agency records show. On 18 different occasions during that period the Coast Guard cited the vessel for an “acknowledged pollution source.” No further details about the type of pollution were immediately available
