ANCHORAGE, Alaska, July 20 (UPI) -- Divers from Shell confirmed that the Noble Discoverer drillship didn't run aground after it slipped its anchor off the Alaskan coast, the company said.
Shell said the drillship slipped anchor and drifted about 300 feet toward the Alaskan coast. It was towed to its original position this week. There were no injuries or pollution reported from the incident.
"While an internal investigation will determine why the Discoverer slipped anchor, we are pleased with the speed and effectiveness of the mitigation measures we had in place," the company said in a statement.
Shell aims to launch a drilling campaign in the Beaufort and Chukchi seas off the Alaskan coast after having its oil-spill response plan approved by federal regulators. The company estimates that there may be as much as 25 billion barrels of oil in the region.
The company said it was committed to "flawless operations" in the area, adding "even a near miss is unacceptable."
