Abstract
A riser extending from a floating rig has a riser manifold. A rig manifold can be manipulated by an arm to couple in an automated manner to the riser manifold when running the riser from the rig. The riser and rig manifolds have mechanical connectors that mechanically connect them. Additionally, the manifolds have flow couplings mating together for conducting flow in at least one flow connection, and the manifolds control couplings mating together for conducting control in at least one flow connection. At least one of the manifolds has at least one valve controllable with the at least one control connection and configured to control fluid communication for the at least one flow connection between at least one rig flow line and an internal passage of the riser.
