Abstract: A capping stack for use with a subsea well includes a ball valve disposed along a first flowline that is axially aligned with a main flowbore of a manifold body so that a tubing string can be passed through the ball valve into the well and whereby the ball valve can be activated to both close the flowline and sever the tubing string as desired. The main flowbore of the manifold body is defined along a primary axis and the capping stack includes second and third flowlines that each intersect the primary axis at an angle greater than zero and that each include a choke mechanism and a pair of spaced apart ball valves disposed along the flowline.

Abstract: A well containment assembly comprising a first pressure-containing device and a diverter spool. The diverter spool comprises a body having a longitudinal central axis and at least partially defining a primary flowbore, an upper connection assembly coupled to the body, a lower connection assembly coupled to the body, and a plurality of side outlets. Each of the plurality of side outlets has a longitudinal central axis and at least partially defines a secondary flowbore. Each of the plurality secondary flowbores is in communication with the primary flowbore, and the angle between the longitudinal central axis of the body and the longitudinal central axis of the plurality of side outlets is less than 90° with respect to the primary flowbore. The first pressure-containing device is coupled to the diverter spool via the upper connection assembly.
