    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.

    Abstract: A compliant seal assembly (38, 56,88, 87, 98, 134, 157, 170, 189, 200, 211) for a rotating machine (10) is provided. The seal assembly (38, 56,88, 87, 98, 134, 157, 170, 189, 200, 211) includes a static member (18, 40, 62,80, 100, 119, 136162, 184, 192, 202, 226), a movable member (20, 50, 66, 82, 102, 120, 120, 138, 168, 176, 210, 216) and a biasing member. The static member (18, 40, 62,80, 100, 119, 136162, 184, 192, 202, 226) is rigidly fixed to the machine (10) at its fore and aft ends. The movable portion has a first sealing surface (48) configured to seal against a rotating member (12, 39) and a rear surface (46), which may be exposed to a fluid pressure to urge the first sealing surface (48) toward a sealing position with the rotating member (12, 39). The static and the movable members further include sealing surfaces at their fore, aft and end faces to seal against leakage of gas between the static and the movable members. The biasing member is configured to support the movable member (20, 50, 66, 82, 102, 120, 120, 138, 168, 176, 210, 216) on the static member (18, 40, 62,80, 100, 119, 136162, 184, 192, 202, 226) and to urge the movable member (20, 50, 66, 82, 102, 120, 120, 138, 168, 176, 210, 216) away from the sealing position so as to reduce force on the rotating member (12, 39) during contact of the rotating member (12, 39) with the first sealing surface (48) of the movable member.

    Abstract: IN A PUMP SYSTEM (10), A PROCESS FLUID IS DIRECTED INTO INLET CHAMBERS (46,48) OF A PUMP CASING AT AN INLET PRESSURE, AND A PLURALITY OF ROTORS (80,82) DISPOSED INSIDE THE PUMP CASING ARE ROTATED TO PUMP THE PROCESS FLUID FROM THE INLET CHAMBERS (46,48) TO AN OUTLET CHAMBER (54) LOCATED BETWEEN THE INLET CHAMBERS (46,48), WHEREIN THE PROCESS FLUID IN THE OUTLET CHAMBERS (54) IS AT AN OUTLET PRESSURE. THE PROCESS FLUID IS DIRECTED FROM THE OUTLET CHAMBER (54) TO A SEPARATOR CONFIGURED TO SEPARATE PARTICULATE MATTER FROM THE PROCESS FLUID, AND A PORTION OF SEPARATED PROCESS FLUID IS DIRECTED FROM THE SEPARATOR TO A GEAR CHAMBER OF THE PUMP. PUMP BEARINGS ARE LUBRICATED WITH THE PORTION OF SEPARATED PROCESS FLUID FROM THE GEAR CHAMBER. SOME OF THE PORTION OF THE SEPARATED PROCESS FLUID FROM THE PUMP BEARING IS LEAKED TO THE INLET CHAMBERS (46,48) VIA ROTOR SHROUDS (78) TO REDUCE ACCUMULATION OF PARTICULATE MATTER IN THE INLET CHAMBERS (46,48).
