| Objectives | To deliver a series of reports relating to Pipeline Noise Mitigation covering: Tests and subsequent results of a selection of different noise mitigation technologies, Identification of a new technique, or techniques, that could be put forward to become a "Best Available Technique",Recommendations for further actions. Success will have been achieved when the reports for each phase of the project have been received and agreed. | |
| Abstract | Noise from gas flowing through pipework can be caused by: Turbulent flow through a straight pipe Turbulent flow past bends or in-pipe disturbances. This can cause extra pressure wave reflections and possible amplification of noise Acoustic and mechanical resonance, which could be further excited by the flow-stream itself or by any pulsations in the flow-stream. Vibrations in the pipe wall caused by: turbulent flow resonances structural noise The currently accepted Best Available Technique to mitigate noise from above ground pipework is to lag the pipe, valves etc. This technique, however, has been known to initiate under-lagging corrosion of pipework, which can then lead to costly remediation work. All Technical Methods; Phase 1 - Technology survey to identify candidate techniques with the potential for being deployed as a Best Available Technique. This may include solutions such as methods to reduce the noise at source, and thereby reduce turbulence in the pipework, e. g. through use of low noise trim regulators, flow straighteners internal to the pipe and external pipework treatments, e. g. constrained layer damping, alternative acoustic lagging materials. Phases 2 and 3 are not costed at this stage but are expected to include: Phase 2 - Laboratory testing of selected technologies This may include noise and vibration testing on small-scale test pieces and integrity/corrosion testing, which could include adhesion, salt spray, and humidity tests Phase 3 - Field trials of the most promising technique(s)Testing would include noise measurements in the vicinity of the pipework, together with vibration measurements on selected locations, both before and after the solution has been implemented in order that the relative improvement can be evaluated.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
