This is not correct. The initial dome/cofferdam would not be placed over the wellhead. They would be placed over the end of the severed riser which is some distance from the well head. The majority of the oil is pouring from this location. Others may be placed over smaller leaks in the riser line as well. There is no plan to place one over the wellhead itself. They need to keep that as clear as possible for additional repairs on the failed BOP unit.
