HoverGuard™

ABB Ability™ UAV-based Gas Leak Detection Solution

HoverGuard™

It enables detection and mapping of natural gas leaks while flying with unprecedented speed, accuracy and reliability.

HoverGuard™ detects natural gas leaks around hard-to-reach sites such as bridges, high-rise buildings, areas with right-of-way restrictions or vegetation coverage, and pipelines.

Advantages

Find leaks fast

Enables detection and mapping of natural gas leaks while flying with unprecedented speed, accuracy and reliability.
Can detect, precisely locate, and estimate the size of natural gas leaks at a rate that covers 10-15 times more land area per minute than traditional methods saving considerable time and allowing users to survey locations inaccessible by road or walking.
Combining patented OA-ICOS™ laser technology, wind velocity and GNNS sensors, and advanced data analytics, the HoverGuard™ solution allows customers to detect leaks far from hard-to-reach sources in minutes.

Proven and accurate technology

HoverGuard™ combines the world’s highest performance laser sensing technology with advanced data analytics and ABB Ability™ to allow customers up and down the natural gas value chain to detect, find, and quantify leaks quickly to increase public safety and improve human health and the global environment.

Data reported in real time

HoverGuard™ starts recording data within a minute after power on to respect your valuable time.
Data visualized (as shown on the left) on Google Earth maps using the same algorithms used successfully in MobileGuard™ our vehicle based system.

Simple to use

HoverGuard™ measures gas concentrations, not path-averaged column densities like other laser-based analyzers that rely on detecting scattered laser light, using its internal measurement cell, fast flow vacuum pump and patented laser absorption technology.
Thus, surveyors can record data by simply flying HoverGuard™ without regard to ground or other external surfaces.

Distribution pipelines, services, and storage sites
Gathering lines
Odor investigation
Construction verification
Post disaster evaluation
Frost line evaluation
Public gatherings
Landfill monitoring
Agricultural studies

The OA-ICOS™ technology advantages

The unique advantages of the patented OA-ICOS technology make ABB’s gas analyzers the preferred choice.

Highest Precision and Sensitivity - combines rugged, reliable near-IR diode lasers with an optical cavity to yield measurements with the highest precision and sensitivity in a simple, robust package. Allows to detect leaks from further away and to locate hard-to-find small emissions.
Widest Dynamic Range - OA-ICOS provides linear response over a much wider dynamic range than conventional CRDS and TDLAS methods allowing to quantify emissions from small or large leaks.
Best Performance - provides unsurpassed overall performance in every important metric (accuracy, speed, linearity, reliability).
Field Serviceable / Minimal Downtime - designed for ruggedness and reliability, in addition to performance. Overall simplicity allows easy service, if necessary.
Better Value - analyzer performance unaffected by minor shifts in optical alignment enabling the use of simpler components and sub-systems.
Comprehensive Platform - ABB uniquely provides a comprehensive platform of solutions based on OA-ICOS technology designed to address any leak detection application.
