Publication number: 20230336252Abstract: A method for use in controlling pressure based signal transmission within a fluid in a flowline includes transmitting a pressure based signal through a fluid within a flowline using a flow control device, recognising a condition change associated with the flowline, and then controlling the flow control device in accordance with the condition change. Another method, or an associated method for use in communication within a flowline includes determining or composing an optimised pressure based signal for detection at a remote location and then transmitting the optimised signal using a flow control device.Type: ApplicationFiled: June 23, 2023Publication date: October 19, 2023Applicant: Tendeka B.V.Inventors: Bard TINNEN, Havar SORTVEIT

Patent number: 10648327Abstract: The flow control device includes a flow path, a compensation chamber and a regulator assembly defining a first surface exposed to the flow path and an opposing second surface which is exposed to the compensation chamber. A drive arrangement is provided for moving the regulator assembly to vary the flow path. Fluid flowing through the flow path establishes a pressure which varies across the first surface of the regulator assembly. The compensation chamber is in pressure communication with a localised region of the first surface which is selected to establish a compensation chamber pressure which acts against the second surface of the regulator assembly to bias the regulator assembly in a desired direction. The first surface of the regulator assembly may define a profile configured to minimise the variation in pressure applied over the first surface by action of fluid flowing through the flow path.Type: GrantFiled: February 20, 2013Date of Patent: May 12, 2020Assignee: TENDEKA B.V.Inventors: Bard Tinnen, Havar Sortveit
