and we will remove the way for the hydrocarbons to exit through the kill and choke lines on the original blowout preventer. then we move to three exit points, the choke and kill lines of the capping stack and then the top opening of the capping stack. then we will in sequence, first -- there are three rams that are part of the capping stack. the middle ram will be closed. that will seal the upper opening from any hydrocarbon release and leaves us the kill and choke lines. the kill line will be closed as well. this is either open or shut. that leaves the choke line of the capping stack as the last way for hydrocarbons to exit from the capping stack. that is set up with a specially designed engineered and built -- it's a horizontal yellow piece of equipment with a piece of pipe and at the other end there's a place to insert a tool with a remotely operated vehicle and then slowly close the valve which we will do that while
