US 11,112,049 B2 · System and method for transient mitigation device in continuous pipelines for surge impact control

Abstract

A device and method to mitigate transient events in a transported medium of fluids and gases subjected to surges, and over pressure events caused by the transient state of a transported medium in a continuous pipeline, where the device has one or more concentrically positioned multilayered composite pipes encased in an outer spool pipe with an annulus space between the spool pipe and the multilayered composite pipes, with flanged adaptors at each end of the device for inline installation in a pipeline, with a management system for receiving, processing and transmitting information gathered in combination with existing pipeline monitoring, and acoustical detection system for receiving and processing of acoustic transmission due to an acoustical wave. Mitigation of pressure events is achieved by energy dissipation and expansion of the multilayered composite pipes and reduction of amplification of pressure waves is achieved by initiation of active counter waves by expansion of the multilayered composite pipes to sinusoidal shape.

A device to mitigate transient events in a transported medium of fluids and gases subjected to surges, and over pressure events caused by the transient state of a transported medium in a continuous pipeline, while acting as a continuous piece of the pipeline, comprising:

a. an outer spool pipe as a casement to one or more concentrically positioned multilayered composite pipes comprising core pipe, helical and circular wrapping layers and sensors and readers, with an annular space between the spool pipe and the multilayered composite pipes, said annular space filled with a fluid medium;
b. end piece adaptors for connection to pipeline open ends when the device is installed inline to the pipeline and where the end piece adaptors each further comprise flanges, chambers for excess pressure mitigation from the annular space, connection for monitoring instruments and an instrumental monitoring port, and;
c. instrumentation and monitoring running longitudinally for the full length of the device.

A method of mitigating transient events in a transported medium of fluids and gases subjected to surges, and over pressure events caused by the transient state of a transported medium in a pipeline, comprising the steps of:
