Nautilus System

For Leak Detection and Gas Pocket Identification in Large Diameter Pressure Pipes.

The Nautilus System consists of a small diameter sphere that is inserted into the network where it travels freely through the pipeline, driven by the water flow. The sounds generated by a leak, air pocket or anomaly have unique characteristics and are captured by the sphere from inside of the pipeline. Once the sphere is extracted, a software developed by our partners, Aganova, processes the compiled information using a mathematical algorithm showing the location of the leaks, gas pockets and anomalies encountered.

Three HydroMax USA workers in masks operate a laptop and sensor equipment from the back of a pickup truck.
Nautilus System Application:
  • Leak Detection: Provides both acoustic verification and a visual spectrum plot of the location of a leak within 6-foot accuracy
  • Network Diagnosis: Provides important information regarding leaks, gas pockets and anomalies that facilitate pipeline rehabilitation/replacement decision making
  • Failure Prevention: Identify leaks and gas pockets before potential catastrophic pipeline failures
  • Deliverables: The final inspection report provides for each identified leak, air pocket, and anomaly a range of observations, including but not limited to:
    • Acoustic recording supported by visual plot (Colorimetry) of the identified discrepancy.
    • GPS /GIS deliverable of all findings and all project appurtenances in ESRI compliant format.
    • Web-based project management/reporting portal.
Nautilus System Benefits:
  • Fast – The Nautilus System can collect data on up to 22 miles of pipeline in one inspection.
  • Flexible – Neutral buoyancy allows for operation at lower flows than tools that roll on the bottom of the pipe.
  • Efficient – Neutral buoyancy allows the device to avoid obstacles like sediment and tuberculation, and easily pass through butterfly valves
  • Effective – Detects leaks as small as 0.15 GPM by being up to 50% closer to the leak than tools that roll on the bottom of the pipe.
  • Versatile – Can be used in all types of pipeline materials at any depth on pipe diameters 10”+
  • Easy – No disruption to pipeline service during deployment.
  • Cost-Effective – The most cost-effective system on the market for leak detection and gas pocket identification in large diameter pipelines. Allows you to survey more pipelines within your original budget.
Insertion

The device is inserted into the pipeline using an insertion system and a 4” or greater pressure valve. This system is used to assure that insertion is done correctly. The system consists of a number of elements designed to place the device inside the pipeline and to assure that its navigation is controlled.

Synchronization and Pass Detectors

The synchronizers and pass detectors are placed along the pipeline at accessible points like valves, etc. The synchronizers support the positioning of leaks, gas pockets and anomalies. The pass detectors provide confirmation of the location of the device during testing.

Extraction

The device is captured and extracted at the end of the pipeline with a net, which is also inserted into the pipeline through an existing air valve or tap. The extraction system is extendable and consists of interchangeable elements adapted to the diameter of the pipeline at the point of extraction. This system is equipped with a camera and an alert system indicating the arrival of the device.
