Safety Requirements Specification Service

aeSolutions provides Safety Requirements Specification (SRS) services to define the functional and performance requirements of Safety Instrumented Systems (SIS) in accordance with IEC 61511. Our structured, lifecycle-based approach ensures that safety requirements are clearly documented, traceable, and aligned with hazard and risk analysis outcomes.

​

Our SRS Capabilities Include:

• Development of SRS documents aligned with IEC 61511 requirements

• Translation of PHA and LOPA results into defined Safety Instrumented Functions (SIFs)

• Definition of SIL targets, functional requirements, and performance criteria

• Specification of process safety time, response time, and trip setpoints

• Documentation of system architecture, interfaces, and design assumptions

• Identification of proof test intervals, diagnostics, and maintenance requirements

• Establishment of cause and effect logic and functional narratives

• Gap assessment and improvement of existing SRS documentation

​

aeSolutions works closely with your engineering, operations, and safety teams to develop SRS documents that are clear, complete, and aligned with how your facility operates. Whether supporting new projects or improving existing documentation, our SRS expertise helps ensure your safety systems are designed, implemented, and maintained in line with your facility’s risk tolerance.
