INSTALLATION OF HIGH MECHANICAL AND ELASTIC RESISTANCE WARNING MESH
The project we present to you today is that of AIR LIQUIDE, the world leader in industrial gases (including hydrogen and oxygen), technologies, and services for the industry (especially healthcare) since 1902. AIR LIQUIDE produces and delivers gas worldwide through pipes or other means of transportation, carefully and intelligently buried in underground networks.
CHALLENGES ENCOUNTERED:
AIR LIQUIDE consulted us as part of this project for the protection of underground hydrogen networks over several hundred meters.
They faced 3 major challenges:
1. To protect and identify gas pipelines located near existing underground electrical networks.
2. To comply with compensatory measures (EMC): The compensatory measures (EMC) to prevent assaults from mechanical digging devices were determined based on the hazard studies established by the company's specifications and respecting the recommendations of GESIP.
3. To carry out a project where logistics and handling during installation needed to be facilitated and secured.

The project we present to you today is that of AIR LIQUIDE, the world leader in industrial gases (including hydrogen and oxygen), technologies, and services for the industry (especially healthcare) since 1902. AIR LIQUIDE produces and delivers gas worldwide through pipes or other means of transportation, carefully and intelligently buried in underground networks.
For one of its clients based in Salaise-sur-Sanne (38), a global leader in animal nutrition, the AIR LIQUIDE group must install an underground pipeline for transporting hydrogen from its production site to the client's site. The use of underground networks is becoming increasingly common as part of a sustainable development approach and as an alternative to truck transport, aiming to reduce CO2 emissions.
To successfully carry out this significant operation, Air Liquide has established specifications and launched a tender for the installation of this pipeline.
Our client DENYS, a major historical player in the installation of underground pipelines and now globally known in the civil engineering world for its large-scale constructions, has been selected to carry out this project.
In the tender established for this operation, AIR LIQUIDE approved the Continuous High Mechanical and Elastic Resistance Warning Mesh (GACTT) from the company ENERGYTEX® / OTEXIO for protecting the underground networks against risks of damage by mechanical equipment (such as excavators).
The project covers tens of kilometers, but a portion is more critical than the rest: the hydrogen pipelines will be buried close to an existing electrical network. The safety and reliability of the network are at stake.

3. To carry out a project where logistics and handling during installation needed to be facilitated and secured.
THE SOLUTION PROPOSED BY ENERGYTEX®:
The high mechanical (HRM) and elastic resistance (HRE) warning mesh - GACTT proved to be the right solution for this project: high puncture resistance, safe and secure unrolling installation, simplified logistics, and reduced cost.
The complete system consists of a base on a woven micro-mesh fabric (here 90cm wide) onto which polypropylene rope is sewn for mesh reinforcement.
The system is completed by a yellow warning device conforming to the EN12613 standard, which runs between the net's frames every 5 meters to make it visible, all in accordance with GESIP recommendations.
The mesh is packaged on a PVC tube to facilitate unrolling installation with machinery to reduce manual handling. It is UV resistant thanks to a packaging film that allows it to be stored outdoors.
WHY DID AIR LIQUIDE APPROVE ENERGYTEX®'s GACTT FOR THIS PROJECT?
The hazard studies conducted prior to the works and submitted to the town hall (with precise mapping of flows) define a level of risk for each underground structure, corresponding to protective measures (called compensatory measures - EMC).
If an underground structure is struck by a mechanical device during works, there is a risk of damage, thus a leak (gas) and explosion, leading to failures/malfunctions of the networks.
The tests conducted under the supervision of APAVE (acting as an independent third party) with our GACTT demonstrated compliance with GESIP recommendations. The DREAL (notably Occitanie) also validated the use of the system for underground structures.
THE SYSTEM OFFERS NUMEROUS ADVANTAGES:
TECHNICAL
- An efficiency coefficient identical to marked concrete slabs and other devices
- 36T resistance to tearing and perforation by machinery
- Approval by an independent third party: APAVE
- The total cost of the system and its installation is significantly lower than that of concrete slabs and/or PE (including excavation and installation)
- Maintenance and upkeep are simple and do not require a camera over the route area
- No excavation costs are expected before the project begins, saving valuable time
- The mesh is made 100% to measure: width as requested (from 0.15 to 3.50m)
- The warning device has an integrated marking band (standard NF EN 12613) associated with the mesh
- Changes in direction and connections are facilitated by the adaptation to the topography of the route
- The overlapping of 2m sheets allows for the continuity of technical characteristics (rolls of 102m)
- The soils are preserved: no warming or cavitation in case of rain.
- Installation is easy with light equipment (compared to concrete slabs)
- A lifespan significantly exceeding 25 years
What motivated the choice of ENERGYTEX® warning mesh?
The custom ENERGYTEX® solution is adaptable to all projects, lengths, and constraints. Its implementation with simplified excavation tipped the balance in favor of ENERGYTEX®, with the safety of operators also being important to our client who preferred a solution with machine installation.
The client's final choice was also based on compliance with protection requirements, as well as the total cost of the system.
Customer Feedback Following the Installation of the HRM/HRE Warning Mesh:
Client installer DENYS shared their satisfaction with the use of the HRM/HRE warning mesh. The ease of installation with mechanical assistance, the unrolling of the mesh along its length, and the ability to cut it to size have saved precious time for the operators on site and allowed the system to be installed in less time than anticipated!
The overlapping of the meshes is also easy to perform and eliminates time wasted handling heavy plates.
The overlapping of the meshes is also easy to perform and eliminates time wasted handling heavy plates.
The space needed on-site for storing the material is also reduced. Additional projects are being considered for 2024.
