Teréga and HyLight test a low-carbon surveillance solution for gas pipelines using an airship

This experiment is part of the systematic leak detection obligations and covers the Cazilhac – Narbonne – Claira section, which is 107 kilometers long. It involves bimonthly overfl ights using the HyLighter airship, developed and operated by Hylight, equipped with a Pergam Falcon+ methane leak detection sensor, in addition to the overfl ights carried out by helicopter.

The objective of this project is to evaluate, under real operating conditions, the capability of an airship to meet the technical, regulatory, and operational requirements for network surveillance, while contributing to reducing the carbon footprint of operations. The HyLighter airship, inflated with helium, flies at low altitude, between 20 and 30 meters, emits no greenhouse gases during flight, and drastically reduces noise pollution compared to helicopters.
