Abstract
Apparatuses useable in an offshore drilling installation close to the seabed for controlling well influx within a wellbore are provided. An apparatus includes a centralizer and flow constrictor assembly, a sensor and a controller. The centralizer and flow constrictor assembly are configured to centralize a drill string within a drill riser and regulate a return mud flow. The sensor 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 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.
