    Abstract: The invention relates to a stuffing box (1 ) consists of an outer housing (2), an upper set (3) and a lower set (4) of support plates for a sleeve-shaped, flexible sealing element (5) enclosed by a liquid filled, pressurised annulus (26). The sets of support plates in the top (22) and bottom of the housing (24) respectively have an opening in the middle, exceeding the diameter of the tool joint (B"). The inner sealing element (5) seals radially against the drill string (B) and axially against the support plates with pressure assistance from the annulus (26) between the sealing element and the middle stuffing box housing. When the sealing element (5) is rotated by the drill string (B) the ends of the sealing element (5) abut the upper and lower support plate set (3, 4) respectively and seals against the pressure from the well and outside seawater pressure. Each of the upper and lower support plate sets (3, 4) comprise two halves (31, 33; 41, 43 respectively) connected to an actuator each (32, 34; 42, 44 respectively) arranged for radial displacement of the halves (31, 33; 41, 43). Each of the support plate halves (31, 33; 41, 43) comprise a cut-out arranged to be able to encircle the inside and the ends of the sealing element (5) comprise cast-in, ceramic elements.

    Abstract: A pressure reduction turbine (1) for a hydrocarbon well stream driving a hydraulic pump (2), and the turbine has two cog wheels (1A, 1B) mounted laterally to a well stream. A deflector plate (1L) is positioned at the well inlet to split and direct the well stream towards the outsides of the cogwheels and to drive them with opposite rotation. The turbine is designed to give a large pressure drop. Ceramics is used in the turbine housing (1C), in the turbine inlet (ID) and in the turbine outlet (1H), to withstand erosion wear. A hydraulic pump (2) is supplied with collective torque via the turbine shaft (IE), supported by two journal bearings (IF and IN) and is connected to the pump via a dynamic sealing arrangement (3). Alternatively the torque from the turbine may be transmitted by to the pump without the dynamic seal, via a magnet coupling. In an underwater implementation the turbine 1 with the pump are equipped with an arrangement for connection or disconnection via an underwater tool system, so that the equipment may be pulled and installed from a surface vessel. The hydraulic pump leads hydraulic oil at high pressure out into a piping system (6) where hydraulic energy, possibly from several such power sources, is led to a common hydraulic motor (7) driving an electric generator (8). In a surface implementation the generator is positioned in a non-explosive environment, for example in an overpressure container (11).

    Abstract: A device for a valve actuator is described, the valve actuator being provided with a slide nut surrounding a portion of an actuator slide and being in engagement with an external threaded portion arranged on the actuator slide, the slide nut being axially fixed relative to the actuator slide, and the actuator slide being in rotation-preventing engagement with a portion of an actuator mounting or a valve housing, and the slide nut being connected to a driving motor via transmission means. Also, a method of operating a valve is described, the method including the step of: providing an axial displacement of the actuator slide by rotating a slide nut which surrounds a portion of an actuator slide, is in engagement with an external threaded portion arranged on the actuator slide and is axially fixed relative to the actuator slide, the rotation being provided with the help of at least one driving motor.
