摘要： A method of maintaining a substantially fixed orientation of a pressure control device relative to a movable rig can include rotating a body of the pressure control device while the rig rotates. A method of remotely controlling an orientation of a pressure control device relative to a movable rig can include rotating a body of the pressure control device, and controlling the rotation of the body from a location on the rig remote from the body. A pressure control device for use in conjunction with a rig can include a body, a flange, an orientation device which changes a rotational orientation of the body relative to the flange, and an orientation control system which remotely controls the orientation device.
