Robert Kaluza was a rig supervisor aboard the
Kaluza was charged with one count of violating the federal Clean Water Act. Jurors got the case Thursday afternoon and reached a verdict after less than two hours of deliberation.
Prosecutors told jurors Kaluza and a former codefendant, Donald Vidrine, botched a crucial pressure test indicating oil and gas could be flowing from deep beneath the seafloor into BP's Macondo well, which was thought to be securely plugged with cement and mud.
"All of the red flags in front of him should have told him that it was a bad test," Assistant U.S. Atty. Gary Winters told jurors after showing them projected images of smoke billowing from the flaming, crippled rig, followed by pictures of oil-coated coastal land.
Defense attorney Shaun Clarke cast Kaluza as a scapegoat. He said federal prosecutors failed to make their case.
Clarke said Vidrine, who has pleaded guilty in the case, was the rig leader who declared the test a success — after Kaluza's watch aboard the rig had ended.
"The Macondo well was under control during every single second of his watch," Clarke said.
Clarke also said other rig workers with 97 years of combined experience in drilling agreed with Vidrine. Clarke disputed Winters' statement that the test was a simple one, saying there were no government standards for the test the prosecution is citing.
"There is no dispute that others were negligent," prosecutor Jennifer Saulino argued later. But Kaluza shared in the negligence that caused the disaster and he should be held criminally accountable for the pollution, she said, as a video of oil flooding from the seafloor flashed on a screen behind her.
Another defense lawyer, David Gerger, argued that failure of multiple, redundant safety systems and equipment caused the explosion, not the interpretation of a test. He pointed to rig crew members failing to notice a "kick," or influx, of oil and gas into the rig hours before the spill; a captain's failure to timely operate an emergency system that would have disconnected the well from the rig ahead of the explosion; and the failure of a crucial device known as a "blowout preventer" that had not been property certified.
Although Kaluza could have faced a year of prison on the pollution charge, he once faced more serious charges. He and Vidrine had been indicted on federal manslaughter and "seaman's manslaughter" charges — 22 counts apiece — stemming from the 11 deaths on the rig. But the seaman's manslaughter counts were thrown out by the courts and government prosecutors late last year backed away from the remaining manslaughter counts.
Prosecutors have recommended no prison time and 10 months of probation for Vidrine. He is set for sentencing in April.
He testified for the prosecution early in the trial, telling jurors that Kaluza never gave him information that prosecutors say was crucial. The information dealt with a test meant to show whether two cement plugs, other structures and drilling mud below the ocean floor could stand up to the pressure of oil and gas farther down.
Kaluza's was the latest in a series of criminal prosecutions arising from the disaster.
In terms of individual criminal responsibility for the spill, only four mostly lower-ranking employees faced charges, and those cases unraveled before skeptical jurors and judges — resulting in plea bargains for lesser offenses or acquittal.
The government did secure a landmark criminal settlement and record civil penalties against the corporation, which BP said would cost it billions of dollars.
