Abstract
A riser extending from a floating rig includes one or more flow control devices having at least one flow connection and having at least one control connection. A riser manifold is disposed on the riser above the one or more flow control devices and has a first mechanical connector, a first flow coupling, and a first control coupling. 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 rig manifold has a second mechanical connector that mechanically connects to the first mechanical connector of the riser manifold. Additionally, the rig manifold has a second flow coupling mating with the first flow coupling of the riser manifold for conducting flow, and has a second control coupling mating with the first control coupling of the riser manifold for conducting control.
