Case Study

The Thessaloniki metro: a cutting-edge project by Engineering

ABSTRACT
The Thessaloniki metro is one of the most important infrastructure works for urban mobility in Greece and its realisation required a high-level engineering approach.

Where: Greece
Challenge
ATTIKO METRO S.A., the public body responsible for managing the project, was faced with numerous challenges: construction in a complex urban and archaeological context, the need to meet stringent European standards, challenging completion schedules, and ensuring maximum safety and technological reliability to offer passengers a modern and safe travel experience.
Approach
To meet the demands of managing technical complexity, safety, and challenging schedules, Engineering adopted a methodological approach based on the IEC 61503 standard, specifically for functional safety in automation systems. This framework enabled the design of a SCADA system that monitors and controls all critical metro operations, including ventilation, lighting and signalling.

The project consisted of:

1. Requirement analysis and identification of the functional specifications of the SCADA system based on requirements, system integration in a complex urban environment, design based on functional safety (IEC 61503).

2. Risk assessment: identification of potential failures and their consequences on the system, design of controls, redundancy and fail-safe.

3. Multidisciplinary coordination and integration with technicians, civil engineers and suppliers.

4. Implementation of a customised SCADA system capable of real-time monitoring and control of all critical operations (e.g. ventilation, lighting, signalling).

In the project, we relied on our main partner Schneider Electric Italia to supply the field technology.
