North Yorkshire based iNPIPE PRODUCTS has announced the launch of a new pipeline blockage and leakage detection product which, using acoustic reflectometry technology, detects blockages, obstructions, or leaks.
Acoustek is believed to be the first product of its type on the market which uses reflectometry – the use of wave and pulse reflections to detect anomolies – can detect full or partial blockages, leaks, and obstructions whilst also checking valve opening speeds and capability.
Acoustek works by connecting directly into a live pipeline and injecting an acoustic pulse which – by measuring the reflected pulse – detects reductions in bore or partially open or closed valves. The system can verify with 100% accuracy the closing efficiency of emergency shut down valves and can accurately detect and locate reductions with a range of up to 10 km from the installation point.
Suitable for complex pipeline networks and providing continuous monitoring capability with remote surveying, Acoustek is easy to integrate with existing pipeline equipment – requiring installation to only one end of the pipe – and can accurately locate blockages or obstructions by up to 10 km.
The technology was recently deployed on a North Sea platform to validate the performance standards of a gas import/export subsea isolation valve (SSIV) required to close within 60 seconds. Situated subsea at the base of the riser, at a water depth of 136 m and located 338 m along the pipeline length – using acoustic data generated from Acoustek – the SSIV was successfully measured, in only one shift, and was determined as closing well within the performance standards required.
