Abstract (en)

[origin: US2015060081A1] A capping stack for use with a subsea well has a body with a flow passageway extending therethrough, a first bore having one end opening to an outlet end of the flow passageway, a second bore opening to the outlet end of the flow passageway, a first flowline affixed to the first bore and extending upwardly therefrom, a second flowline affixed to the second bore and extending upwardly therefrom, a first valve cooperative with the first flowline so as to be movable between an open position and a closed position, and a second valve cooperative the second flowline so as to be movable between an open position and a closed position. The inlet end of the flow passageway is suitable for connection to a blowout preventer or to a wellhead of a subsea well. Each of the bores extends upwardly at an acute angle to vertical from the flow passageway.
