CGH Belgium started a collaboration with Eliot in the Oil & Gas sector for the identification of underground piping networks
ELIOT (Location and Identification Equipment for Underground Networks) is a patented system based on tried and tested technology:
RFID (Radio Frequency IDentification), specifically used in electronic motorway tolls or biometric passports.
ELIOT thus uses electromagnetic energy to locate and identify underground networks and the system consists of three main components:
- A marker containing the data of the component to be identified: fixed onto the piping, this marker is a passive system requiring no electrical power.
It takes its energy from the electromagnetic waves emitted by the reader antenna.
- A reader, which exchanges data (read/write) with the marker via an antenna and displays it directly on the screen.
- Software that processes data and imports it into any type of Geographic Information System (GIS) or asset management software.
ELIOT ensures three essential functions:
- Simple and intuitive, the location of an underground structure requires no specific training.
- The information contained in the marker is displayed instantly and clearly on the IHM screen: no extrapolation required.
- Location works for depths of up to 1.50 m, with unprecedented precision of around one centimetre on three axes: X-Y-Z.
- It is effective in all environments: all soil types (tarmac, sand, earth, stones, dry soils, wet soils, etc.), even in watery environments (water tables,
- Whatever the type of materials (cast iron, concrete, PEHD, etc.) and network/grid usage (water, gas, electricity, telecommunications, etc.).
- With a long expected lifetime: of around a century.
- Closed excavation georeferencing
- The display of all types of networks equipped with the ELIOT marker located in the area of activity is simultaneous: response time equivalent to a
thousandth of a second.
- The signal measured on the surface enables the very precise identification of the pipework detected, thereby avoiding any confusion if several
networks are nearby.
- The system’s considerable data storage capacity makes it possible to finely distinguish the underground structure: pipe type, use, date of installation,
serial number, diameter, etc.
- The option to add information makes it possible to enter information about the installation environment and make the area safe for future work.
- Recovery of information stored in the RFID tags then association of GPS coordinates of each point and integration in any type of GIS.
- Easy to write in the TAGS thanks to the Android application.
- Possibility of locking the added information.
