Abstract:
A connector assembly that can be used to connect a tension ring to a telescoping joint on a riser by using a lower set of hydraulically actuated dogs. A set of hydraulically actuated hang-off dogs on the connector assembly can be used to connect the tension ring to a diverter housing mounted on a rig. To prevent accidental disengagement of the hang-off dogs, a hydraulically actuated lock ring is used to provide a positive stop against the back of the hang-off dogs.
