Hifi Announces New Pipeline Pig Management Application and Two New Patents 2/19/21

Hifi HDS providing more value-added commercial applications in addition to preventative pipeline leak detection

Hifi Engineering Inc., a developer and supplier of next generation fiber optic sensing technology used to monitor assets including pipelines and oil and gas wells, today announced the company has released the HDS Pipeline Pig Management Application (PMA) for pipelines as part of their patented high fidelity distributed sensing (HDS™) platform. HDS is a specialized data interrogation and analysis platform which uses advanced machine learning and artificial intelligence software algorithms to support Hifi’s high fidelity fiber optic sensors.

The new PMA allows pipeline operators to use the HDS 2.0 platform and web-based HDS Monitor pipeline monitoring interface to manage pipeline pig detection and tracking for their pipeline networks. Pigs are sensed and tracked automatically. The pipeline operator can optionally pre-enter pig identifying information such as a unique ID and final destination into the system. Alerts can be enabled to track the pig by time or by location, including the speed and relative strain of the pig as it travels through the pipe. The web-based HDS Monitor pipeline monitoring interface software will provide notifications to the pipeline control room if a pig stops unexpectedly and when the pig run has been completed.

"The PMA is a great addition to the HDS system,” said Ehsan Jalilian, Vice President Systems Engineering for Hifi. “This application will greatly simplify and streamline our operational processes, and will save our customers time and money through pinpointing the location of issues encountered during pigging operations.”

Hifi also announced two new patents:

US16/805,277: HDS Event Detection Algorithm
This patent covers Hifi's pipeline event detection algorithms, including its preventative leak detection algorithm. Hifi applies its leading-edge signal processing algorithms to the distributed high-fidelity data acquired from its fiber optic sensors. This patent recognizes Hifi's innovative approach to pipeline event detection, with a strong emphasis on the accurate detection of events without false positives.

US15/773,965: Versatile Pipeline Field Leak Simulation System
This patent recognizes Hifi's innovative approach to designing and conducting field leak simulations to test the effectiveness and readiness of its HDS pipeline monitoring system. The patent covers the design of an easy to deploy leak simulation system which is capable of simulating gas and liquid leaks on or near a pipeline, with maximum control provided to the operators in order to simulate leaks with various pressures, flow rates, and nozzle sizes. This innovation enables the operators to remotely trigger leaks (on a scheduled basis or on demand) and provides a feedback mechanism to notify the operator of the successful execution of the leak simulation.

“We are very pleased with both the launch of Hifi’s Pipeline Pig Management Application and these additional patents supporting the HDS 2.0 platform,” said Steven Koles, Hifi’s President and CEO. “These internally developed innovations help support preventative pipeline leak detection, as well as our other operational applications which help support environmental, social, and governance (ESG) scorecard objectives of our pipeline partners.”

Hifi will be providing a webinar for the Fiber Optic Sensing Association (FOSA) on February 18th titled “Retrofitting Existing Pipelines for Fiber Optic Monitoring”. Registration for the webinar can be made at:
