Abstract
A multipurpose latch assembly (MPLA) for installation above the bore of a blowout preventer includes an annular sidewall extending between a top flange and a bottom flange and having an interior bore surface defining an interior bore. A plurality of latching slots extend through the sidewall and a latching dog is slidably positioned in each latching slot. Actuators are connected to the latching dogs to extend and retract them through the latching slots. A tool having an external slot can be inserted into the bore of the MPLA and selectively engaged by the latching dogs to secure the tool in the bore of above the blowout preventer.
