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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The device of claim 1 where the outer spool pipe is of multilayered composite material and the device can be assembled in hose form capable of being flat coiled. ### Claim 3 (depends on 1) The device of claim 1 further designed to reduce amplification of transient pressure waves by simulation of counter waves where the end piece adaptors further comprise a contra wave injector to extend the annular space to expand the multilayered composite pipes to sinusoidal shape within the outer spool pipe. ### Claim 4 (depends on 3) The device of claim 3 further comprising annulus spacers to provide for orientation of sinusoidal movement of the multilayered composite pipes. ### Claim 5 (depends on 4) The device of claim 4 further comprising a management system for receiving, processing and transmitting information gathered from the instrumental monitoring port on each end piece adaptor and in combination with existing pipeline monitoring. ### Claim 6 (depends on 1) The device of claim 1 further comprising an acoustical detection system for receiving and processing of acoustic transmission due to an acoustical wave generated from heat and pressure detected through an acoustic micro pack. ### Claim 7 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: a. installing an inline device to function as both a mitigation device and fully functional pipeline component in the pipeline where said device comprises: 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; 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; instrumentation and monitoring running longitudinally for the full length of the device; b. monitor increased pressure events in the pipeline by installing a management system for receiving, processing and transmitting information gathered from the instrumental monitoring port on each end piece adaptor and in combination with existing pipeline monitoring; c. allow the inline device to mitigate high pressure impact by energy dissipation. ### Claim 8 (depends on 7) The method of claim 7 where the installed inline device further comprises a contra-wave injector to extend the annular space to expand the multilayered composite pipes to sinusoidal shape within the outer spool pipe, and in response to a pressure wave in the pipeline the multilayered composite pipes are expanded to a sinusoidal shape to initiate an active counter wave to the pressure wave to reduce amplification of the pressure wave. ### Claim 9 (depends on 8) The method of claim 8 where the inline device further comprises an acoustical detection system to detect an acoustical wave generated from heat and pressure in the pipeline and upon detection of an acoustical wave, initiate a response to protect the pipeline.
