p-CAT™

The deteriorating state of water infrastructure can result in pipeline failures, emergency repairs, reduced reliability and economic loss

The application and use of innovative pipeline technologies has become more critical as expectations and goals associated with infrastructure expand. By leveraging condition assessment technologies and turning data into actionable results, utilities can assess risk and prioritise assets in need of rehabilitation or replacement. This allows them to allocate resources more effectively to optimise the reliability of their pipelines.

Understanding pipeline conditions allows for strategic and tactical decisions. p-CAT™ Nexus and p-CAT™ Infinity provide a comprehensive solution using non-invasive, non-destructive technology.

p-CAT™ Nexus

Is a non-invasive, non-destructive technology for performing pipe condition assessment. p-CAT™ Nexus can determine remaining wall thicknesses over long sections (many kilometres) of pipeline as well as detecting and locating defects such as air and gas pockets, internal blockages and restrictions, unknown connections, pipe material changes and cement matric loss from metallic, concrete and AC pipes.

p-CAT™ Nexus works by analysing the partial reflection of a small, controlled transient signal that is injected into the pipeline. The signal is monitored and recorded by sensors that are temporarily installed on existing pipe fittings. The transient wave experiences partial reflection when it encounters any change in pipeline structure, including both known features of the system as well as other issues related to pipe deterioration. p-CAT™ Nexus can be applied on any pressurised fluid filled pipeline carrying potable, raw or wastewater and saves on costs by locating defects within the pipeline and limiting repairs and replacements to only the sections in need of attention. To date, p-CAT™ Nexus is the most comprehensive and advanced solution for long distance pipelines.

p-CAT™ Infinity

Also uses the p-CAT™ Nexus unique patented and proven technique of inverse transient analysis to measure and determine the wall condition and thickness of pipelines, however there is a difference. The Detection Services approach is to provide an expansion and extension of the p-CAT™ Nexus application (suite), with the advantage that p-CAT™ Infinity reduces the need for sometimes complex works such as offtake isolations. This technology can be applied on different and varied system configurations and allows for a substantial reduction of time from inception and implementation through to analysis and solution. This allows for an increase in efficiency with a focus on opportunity to extend the lifecycle of the asset and maximise value.
