Functional Safety Engineering Support
Supporting Safety Instrumented Functions and Systems
Functional safety is an important part of managing risk in industrial processes where safety-related control functions are required.
Premium Safety Solutions provides functional safety engineering support tailored to the project scope, lifecycle stage, and applicable requirements.
Safety Integrity Level (SIL) Assessment
SIL assessment evaluates the required level of risk reduction associated with a safety instrumented function, using an appropriate methodology and agreed assessment criteria.
Support may include:
Review of relevant process safety scenarios
Assessment of the required risk reduction
Application of an agreed SIL assessment methodology
Documentation of assumptions and results
Support for related process safety studies
SIL Verification
SIL verification evaluates whether a proposed or existing safety instrumented function meets its specified integrity requirements, based on relevant design information and assumptions.
Depending on the agreed scope, support may include review of system architecture, reliability data, failure-rate assumptions, and relevant calculation inputs and results.
Safety Requirements Specification (SRS)
The Safety Requirements Specification documents the requirements that a safety instrumented function must satisfy.
Support may include development or review of the SRS to help ensure that relevant functional, integrity, interface, and lifecycle requirements are appropriately documented for the intended application.
Safety Instrumented System (SIS) Reviews
SIS reviews examine relevant aspects of safety instrumented system design and documentation against agreed project requirements and applicable standards.
The scope may include review of functional requirements, design documentation, verification information, and identified gaps or outstanding actions.
Lifecycle-Oriented Support
Functional safety activities must be appropriate to the relevant lifecycle stage and the responsibilities defined for each project.
We work within the agreed scope and available information, with deliverables and review boundaries established before the work begins.
