BP was forced to remove the oil cap which was capturing oil from the Deepwater Horizon oil rig. Currently, there is no containment system over the oil spill.
Nola.com reports that an underwater robot bumped into a venting system, which sent gas rising through the vent. Coast Guard Adm. Thad Allen said that BP removed the cap to make sure that no ice-like crystals were forming on the cap.
“Out of an abundance of caution, the Discover Enterprise removed the containment cap with the riser pipe… until they could assess the condition,” Adm. Allen said.
BP is still burning oil on the surface, and if no crystals are found, they plan to have the cap back in place later on today.
“If there are hydrates (crystals), they will probably have to rerun the pipeline and that will a considerable amount longer,” Adm. Allen said.
Before the problem with the containment cap, BP reported that the cap had captured 700,000 gallons of oil in the past 24 hours.
