Complete system assurance and RAMS
We carry out the full reliability, availability, maintainability and safety (RAMS) lifecycle in-house, for our own products and as a service for customers and system integrators.
RAMS management
RAMS planning, specification and demonstration across the system lifecycle, per EN 50126.
Hazard analysis
System hazard identification, risk assessment and hazard log management, with mitigations traced to design.
Reliability analysis
Reliability prediction (MIL-HDBK-217F), FMECA and fault tree analysis to prove MTBF and availability targets.
Safety case
Safety case preparation to EN 50129, with software developed and documented to EN 50128.
Verification and validation
Structured V&V of hardware and software against requirements and SIL targets.
Independent assessment support
Coordination with accredited independent safety assessors through to certification. Our SSDAC was assessed SIL 4 compliant by Bureau Veritas Italy.
