Pipeline leak detection: Technologies for peace of mind
In this webinar, TechnipFMC’s Brian Woods and Daniel Mabily cover two unique technologies for addressing leak detection, how they operate and ways to optimise them in a multilayer configuration as part of a pipeline integrity solution.
Pipelines are subject to numerous threats including third party damage, corrosion, mechanical failure of pumps and valves, land movement, and illegal tapping. These threats may lead to uncontrolled releases of products. The impact on human life and the environment can be significant. The pipeline operator’s public image can be damaged with non-negligible economic or political consequences. TechnipFMC's leak detection solutions have been developed to minimise the consequence of leaks from onshore and offshore pipelines.
PipeLIDS - PipeLIDS uses acoustic technology to detect the noise generated by impacts or leaks. This noise propagates in both directions over long distances inside the pipeline. Intrusive acoustic sensors are installed regularly on the pipeline (every 10 km) to detect this noise. Each sensor is connected to an intelligent beacon with GPS synchronisation. By measuring the sound wave’s amplitude and phase time shift and analysing the acoustic signature, PipeLIDS detects the origin and location of the event and raises an alarm.
LeakNet™ - LeakNet’s PPA algorithm uses Negative Pressure Wave Detection to identify the leak expansion wave as it travels along the pipeline. PPA’s optional Locator module identifies the location of the leak. LeakNet’s MassPack algorithm uses Modified Mass Balance to track unaccounted inventory over time, and identify the presence of a leak. LeakNet™ is compatible with industry standard pressure and flow instrumentation.
PipeLIDS and LeakNet™ are part of TechnipFMC’s multilayer line integrity solution.
