As oil again again flows freely, crews are working around the clock to replace a containment cap on the ruptured underwater well in the Gulf of Mexico, BP said Saturday.
The company hopes to install a better-fitting one in the coming days, BP senior Vice President Kent Wells said.
"We're on plan," he said hours after the old cap was removed.
Live video showed robots in the process of removing six bolts from the apparatus so that the new cap can be positioned. The bolts may all be removed by Sunday.
