Abstract
A subsea mineral extraction system including a subsea riser system comprises a rotary table positioned within a drilling rig, an operational joint configured to connect to and alter flow through the subsea riser system, in which the operational joint passes through the rotary table. An annular blowout preventer joint for the subsea mineral extraction system is passable through the rotary table of the subsea mineral extraction system, and a diverter joint for the subsea mineral extraction system is passable through the rotary table of the subsea mineral extraction system. Further, a connector for receiving flow therethrough includes a body with a seat including a keyed groove, a stab including a key, and a locking member to retain the key within the keyed groove of the seat.
