SoundPrint® Acoustic Fiber Optic Monitoring

Preventing large-diameter pipe failures is a primary concern for asset managers, who face costs between US$500,000 and US$1.5 million. Fortunately for owners of prestressed concrete cylinder pipe (PCCP), Pure’s SoundPrint® Acoustic Fiber Optic (AFO) Monitoring technology is an industry-leading system that tracks and records pipeline deterioration. Pure’s monitoring systems are installed on more than 600 miles (1,000 kilometers) of PCCP around the world and have prevented a number of high profile failures.

Once installed in a pipeline, the SoundPrint AFO system remotely detects the acoustic signature of wire breaks in PCCP, and records their specific pipe location. If break activity increases, utility staff are alerted and can intervene on the deteriorating pipe in advance of a failure.

PCCP monitoring is often partnered with baseline electromagnetic (EM) inspection to create intelligentinfrastructure. The baseline EM inspection identifies the amount of existing wire wrap breaks in each section of PCCP at a point in time, while the SoundPrint AFO system continuously monitors the same pipe sections for ongoing deterioration. Combined with a detailed engineering evaluation and structural analysis, a determination can be made about the wire break limit of each pipe section. As the monitoring system records breaks and the pipe section approaches its limit, pipe sections can be proactively rehabilitated in advance of an expensive failure.

SoundPrint AFO Advantages:

  • Detects actively deteriorating PCCP sections
  • System installation does not affect pipeline operation
  • Proven history and the most reliable acoustic monitoring technology for PCCP
  • Flexible monitoring solutions for installation around valves, bends, and outlets
  • All wire breaks are located and reported in near real-time through a web-based reporting system

SoundPrint AFO is Applicable for:

  • Prestressed concrete cylinder pipe (PCCP)
  • Potable water, raw water, and wastewater
  • Pipelines 24 inches and larger

In response to aging and deteriorating PCCP, some of the largest utilities in North America are proactively monitoring their assets with EM inspection, AFO monitoring and structural analysis. This proven approach has been successful in selectively rehabilitating PCCP assets – while preventing critical failures – for only a fraction of the cost.
