Abstract: The invention relates to a method of using new flushing ports (IA7 IB) when cleaning a piston accumulator (7). Dirty hydraulic oil is returned out via the main port (2) and a return passage (9) until a cleanness grade has been reached. Clean hydraulic oil is forced into the piston accumulator (7) via the axial bores (3A, B) of the flushing ports (IA, B) and further in sloping bores (3C, D), bringing the hydraulic oil into the volume (8) in an upward, tangential direction below the piston (5), into a flushing circulation. By reducing the gas pressure on the gas side (4) of the piston (5) in relation to flushing pressure input from a valve (6), a volume (8) is created on the oil side between the piston (5) and the end bottom (3). The return passage (9) is closed and the piston (5) is brought into its upper position, so that an internal cylinder wall (10) is cleaned. Upon pressure build-up, the return passage (9) is opened, and the piston (5) returns to its end position on the oil side while the supply of clean hydraulic oil is maintained, and the operation is repeated until a cleanness grade has been achieved.

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 downhole pressure- and vibration- measuring device integrated in a pipe section (1) as part of a production tubing (20). The sensor housing (2) of the measuring device with sensors has a two-part clamp (3) on the upper part of the sensor housing (2), from where an electrical multi- conductor cable connection (10) from at least four, preferably six, nipples in a tube (9) is clamped along the production tubing (20) with bushings through equipment installed in the wellhead to sensors with an electronics and control unit (12) above the wellhead. Evenly- spaced radially in an annular space (5) are a first set of strain gauges (7) attached to the outside wall of the production tubing (20) and a second set of strain gauges (8) attached on the inside of the external wall of the sensor housing (2). Strain gauges (7, 8) are connected by glass penetrators (4) of electrical conductors in cable tubes (9A) terminated in the tubing hanger (21) to an electronics unit (11) and a control unit (12). For the measuring of temperatures, a thermometer will be integrated. Pressure -measurement signals also measure vibration in the production tubing (20).

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.
