4.Electrical and Operations Equipment
The Electrical and Operations Equipment department is involved in the design, implementation and life cycle of electrical equipment* in tunnels, including technical, technological and financial aspects.
* Ventilation and air quality equipment is handled by the Ventilation and Environment department.
This includes equipment for:
- power supply and distribution,
- signalling and tunnel closure systems,
- lighting,
- automatic incident detection (AID) and video surveillance,
- radio communications,
- emergency call networks,
- telecommunications and IT networks,
- control and command systems (SCADA etc.),
- The Electrical and Operations Equipment department is also involved in cross-functional fields such as cybersecurity, operational safety and energy consumption.
Its activities encompass design and construction, control and inspection, and support for innovations.
The Electrical and Operations Equipment department provides support for numerous engineering operations. The data and experience gained from these operations enables the department to analyse and pool knowledge in order to contribute to the development of technical guidelines in its fields.
In addition, the Electrical and Operations Equipment department contributes to the drafting of regulations by participating in professional associations and standardisation committees on tunnel equipment: CIE, CEN, AFNOR, etc.
Assistance during design and works
The Electrical and Operations Equipment department advises and assists project owners and project managers in all phases of road tunnel equipment projects, whether for new installations, renovations or specific areas of expertise: diagnoses, design and/or design, technical and financial analysis, technical specifications, field measurements, tests and approvals, etc.
Equipment verifications and inspections
The equipment inspection team of the Electrical and Operations Equipment department conducts initial and periodic comprehensive inspections of tunnels on the State-managed road network. It plays a key role in developing professional guidelines by designing and testing inspection methods and tools. The data collected during these inspections provides a wealth of feedback and provides input for the department’s strategy and activities in many fields.
The equipment inspection team’s role is also to support the profession in applying and rolling out inspections across the rest of the road network.
Supporting innovation
Technological innovations in the field of equipment and control systems are changing how tunnel equipment is used and implemented. The Electrical and Operations Equipment department is heavily involved in applied research, both internally and in partnership with the industry, to explore and assess innovations with the following objectives:
- identify significant innovations for the various types of equipment mentioned above, analyse the challenges they pose and promote their development;
- gather feedback to improve the operation and performance of equipment deployed in tunnels with a focus on operational safety;
- control costs and limit consumption; the objective of environmental and energy efficiency is fundamental in the current context;
- optimise equipment inspection methods; which play a central role in guaranteeing safety.
