The activity involves 360° consultancy to the customer for the creation of all the documentation necessary for the SIL2 certification of the new system and for the AMIS Homologation activity of the modification in compliance with the ANSF Guidelines 1/2019 Rev. 02.
The activity also includes the drafting of SW life cycle documents in SIL2 and the related V&V activities as required by the EN 50657 standard.
In addition to the drafting of the safety and RAMS analyzes necessary to technically support the certification and AMIS, consultancy was provided to the customer for the creation of documentation of compliance with the F&S requirements according to EN 45545-2.
CENELEC standards: EN 50126, EN 50129, EN 50128/EN 50657
– New Train for Regione Lazio PA Emergency Announcement SIL2 [2023-2024]
Safety analysis of passenger announcement and emergency call alarm functions. For the PA-PIS system soon to be installed on the new New Trains for the LAZIO Region Metropolitan Network (Rome-Lido, Rome-Viterbo configurations). The customer is supported in drafting the Safety Case for SIL2 certification, RAMS analyzes and F&S compliance documentation according to EN 45545-2 and Ecodesign.
It supports the customer from the beginning of the concept phase of the system by providing design guidelines for SIL safety systems, and has taken charge of the creation of the Safety Case and the management of the SIL2 certification by directly managing relations with the ISA in charge of the assessment and certification activities of the safety system in compliance with the EN 50126, EN 50129 requirements.
CENELEC standards: EN 50126, EN 50129
– FCE Metro PA-PIS Safety Analysis [2021]
Safety analysis of passenger announcement functions and emergency call alarms. For the PA‐PIS system soon to be installed on the new trains of the new Catania metro (FCE), the customer was requested to perform a safety analysis in compliance with the railway standards (EN 50126, EN 50129) on Top events ( hazards) output of the risk analysis carried out at train level for which a Tolerable Functional Failure Rate (TFFR / THR) target of at least 10-7 is assigned. Furthermore, methodology consulting is provided for realization of the Software Quality Assurance Plan (SWQAP) and V&V in compliance with EN 50128 – CENELEC Standard: EN 50126, EN 50129, EN 50128
– Metropolitana Thessaloniki Rolling Stock Safety Case [2019-2020]
Technical review analysis of the RAMS documentation of the Safety Case (Rolling stock part) of the Thessaloniki Metro project in order to produce a technical assessment and comments on the general compliance of its content with the objectives expressed by the reference standards of railway functional safety – Standard CENELEC: EN 50126, EN 50129, EN 50128
CIVIL – ANTISISMIC
[2020-2021] Safety analysis and methodological consultancy for the design and management of the functional safety of an innovative seismic control system. The system is made with an intelligent active technology for the seismic protection of existing buildings that is installed on the roof of the buildings with the aim of protecting them in total autonomy in the event of an earthquake.
As there is currently no specific functional safety product standard for the sector, we collaborated with the certifying body in charge of the safety assessment activities to define the methodological approach and the reference regulatory framework to be able to perform a Preliminary Hazard Analysis and a SIL Allocation on safety functions – Standard IEC 61508, NTC 2018.
INDUSTRY
[2020] Specialist and methodological consultancy for the design of a safety system for the application of collaborative Human-Robot interaction in compliance with IEC 61508, EN 62061 (SIL 2) and EN 13849-1 (PLd).
[2017-2018] Support to the R & D department with methodological consulting for the design of their product line PSD (Electrical Motor Power Drive System) with safety function in accordance with the product standards IEC 61508-2 (HW), IEC 61508-3 ( SW SIL 3), EN 62061.
OIL and GAS
[2018-2019] Engineering and Project Management consultancy for an electronic fire detection and extinguishing control system with safety function in compliance with the product standards IEC 61508-2 (HW), IEC 61508-3 (SW SIL 2/3 ), EN 54. The activity foresees the coordination, the methodological advice and the supervision to the SIL design with the setting and the verification of design guidelines of the system architecture and of the individual electronic modules to meet the SIL2 safety requirement until obtaining the certification. The activity includes qualitative and quantitative safety analyzes with reliability calculations, FMEDA and SIL verification (PFH, PFD). The consulting activity provides for the management and interface with the accredited certification bodies in charge.
MEDICAL
[2020] Design support consultancy for the execution of a DFMEA (Design Failure Mode Effect Analysis) analysis on a “principal user-interface” terminal for medical device application (Mobile X-ray systems). IEC 60601 standard.
