Abstract: The invention relates to a downhole pressure- and vibration-measuring device integrated in a pipe section as part of a production tubing. The sensor housing of the measuring device with sensors has a two-part clamp on the upper part of the sensor housing, from where an electrical multi-conductor cable connection from at least four, preferably six, nipples in a tube is clamped along the production tubing with bushings through equipment installed in the wellhead to sensors with an electronics and control unit above the wellhead. Evenly spaced radially in an annular space are a first set of strain gauges attached to the outside wall of the production tubing and a second set of strain gauges attached on the inside of the external wall of the sensor housing. Strain gauges are connected by glass penetrators of electrical conductors in cable tubes terminated in the tubing hanger to an electronics unit and a control unit. For the measuring of temperatures, a thermometer will be integrated. Pressure-measurement signals also measure vibration in the production tubing.

Abstract: The invention relates to a method for measuring and controlling a fluid flow in a pipe system for liquid transport, such as oil flow during buoy loading, wherein there in each end of a the pipe system is spliced in a sensor (1) consisting of a pipe section (2) with a reinforced rubber bellows (3) positioned as a restriction within the transport pipe. The rubber bellows (3) is forced radially outward when there is oil flowing through the transport pipe, and compresses a gas filled volume in a pressure vessel (4) via a pipe connection (4B) in communication with an annulus (5), and a pressure transmitter (6A/B) gives signals to a control system (7). The sensor (1) on the platform and the tanker vessel measures relative changes in the liquid flow between the two measuring points, as the measurements from the tanker vessel is received via a telemetry system, and the signals from the two measuring points are compared continuously by the control system on the platform, which triggers an alarm and shuts down the loading process automatically at deviation in the measurement on the tanker vessel compared to the reference measurement on the platform.

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.
