Protect investments and prioritize renewals with Nautilus.

The inline leak and gas pocket detection solution for large-diameter pressure pipelines.

understand the present | protect the future

For leak detection and gas pocket identification in large diameter pressure pipes.

Originally developed in Spain in 2015 by Aganova, the Nautilus System was introduced to the US market by Hydromax USA. The system consists of a small, neutrally buoyant sphere that is inserted into the network where it travels freely, driven by the flow of water in the pipe. Sounds generated by a leak, gas pocket, or anomaly have unique characteristics. The device captures the sound of these from inside the pipeline. Once the device is extracted, software processes the compiled information using a mathematical algorithm to determine the location of leaks, gas pockets, and anomalies encountered.

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.

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.

How it works?

Insertion The device is inserted into the pipeline using an insertion system and a 4” or greater pressure valve. The system consists of several elements designed to place the device inside the pipeline and to ensure that its navigation is controlled.
Synchronization The synchronizers are placed along the pipeline at accessible points like valves, etc. The synchronizers support the positioning of leaks, gas pockets, and anomalies.
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 indicating the arrival of the device.
