The Project Scope for AS Hellas
The project scope for AS Hellas includes the following:
- Study, design, and construction of the 42 automation panels (SSS, SNS, RIO, LCP) for the 5 new stations and 2 new shafts in the Copenhagen Metro expansion project.
- Software development (compliant with EN 50128 standards) for the automation system of each station, controlling subsystems such as:
- Emergency Ventilation System
- Fire Alarm System
- Fire Fighting System
- Drainage System
- Flood Gates
- Low Voltage System
- Lighting System (DALI)
- Lifts & Escalators
- Quality Documentation for delivered equipment and software (NOM, HMI Specifications, EN50128 docs, O&M, Training material, Activity sheets, Spare part lists, Asset lists)
- Project auxiliary documentation (Shop drawings)
- Tests Documentation for delivered equipment and software (FAT, ITP, WIR, COM, SAT, SIT)
The software focus primarily involves the Building Management System (BMS) of the stations. However, specific safety specifications required industrial automation hardware. The result is a system that effectively combines the advantages of Industrial and Building Automation.
A project spanning 3.5 years, demanding exceptional project management skills, documentation, and strict adherence to the project schedule and specifications.
Additions to the Project
Throughout the project, three additional tasks were assigned to us related to equipment automation not provided by the main suppliers of the consortium. Specifically, an automation system was requested for the Skylights equipment, the DALI system for lighting, and the central fire extinguishing pump station.
Especially for the DALI system, this was implemented for the first time in the Copenhagen Metro project, leaving a particularly positive impression on the client from AS Hellas’ implementation.
The study and construction of the panels were based on strict specifications, aligned with the most rigorous construction standards for relevant automation panels.
The architecture of the automation system is based on seven autonomous stations with redundant PLCs, each controlling subsystem installed locally, according to the operation scenarios of the installed SCADA system. Each station communicates separately with the central SCADA system of the entire Copenhagen METRO, as shown below, exchanging commands and information in real-time.
The project’s total control points, exceeding 6,500, are categorized based on their security level (SIL).
As of the beginning of 2024, AS Hellas is in the final stage of commissioning, successfully completing the project without any deviations from the schedule. The commissioning process required the continuous presence of a large team of our engineers over a six-month period.
Key elements of the project:
The successful completion of the project is a significant achievement for AS Hellas, as it involved handling a demanding project with several distinctive features, outlined below:
- First assignment of a large and demanding infrastructure project in a Northern European country.
- The development of SIL software, according to the EN50128 standard, was required for the first time.
- The volume of documentation surpassed 10,000 pages, an unprecedented scale.
- This marks the first instance where our presence was required for commissioning in a foreign country for an extended and continuous period (6 months).
- Additionally, it’s the first time that the presence of a large team was necessary for commissioning in a foreign country simultaneously (2 months).
