containment dome is a component of the system designed to contain the underwater blowout of an oil well such as occurred with the Macondo Well blowout from the Deepwater Horizon oil spill . This portion of the system is designed as a vacuum to suck up the products being expelled from a blowout and deliver those products to the containment system housed on the vessel moored above the blowout . Superior Energy Services is constructing this device to be used by Shell Oil Company on the barge '' Arctic Challenger '' as their " fourth line of defense " against a blowout in the Arctic drilling regions in the Chukchi Sea and Beaufort Sea
