Welding the dome

Welders work near the BP Pollution Containment Chamber at Wild Well Control, Inc. in Port Fourchon, Louisiana May 3, 2010. The system is made up of a 125-ton structure that will be set on top of the largest leak source. This leak is located at the end of the riser, about 600 feet from the wellhead. Energy giant BP Plc, its reputation battered by a catastrophic oil spill threatening the U.S. Gulf shore, said on Monday it was working to stem the gushing undersea leak and promised to pay for the cleanup and compensation claims. BP is working on to try to seal the ruptured well with the undersea containment system that would capture the leaking oil and channel it to a tanker on the surface. REUTERS
