Abstract

Apparatuses 100 useable in an offshore drilling installation close to the seabed 110 for controlling well influx within a wellbore are provided. An apparatus includes a centralizer and flow constrictor assembly 128, a sensor 154 and a controller 157. The centralizer and flow constrictor assembly are configured to centralize a drill string 112 within a drill riser 106 and regulate a return mud flow 118. The sensor 154 is located close to the centralizer and flow constrictor assembly and configured to acquire values of at least one parameter related to the return mud flow. The controller 157 is coupled to the centralizer and flow constrictor assembly and the sensor. The controller is configured to control the centralizer and flow constrictor assembly to achieve a value of a control parameter close to a predetermined value, based on the values acquired by the sensor.
